These ulcers usually appear within a few weeks following drug treatment. In most of cases, these ulcers resist to conventional treatments, such as anesthetics, antiseptics, anti-inflammatory agents, cauterization, topical tetracycline and corticosteroid treatment. The diagnosis is usually difficult, especially in patients receiving multiple drug therapies. Hyaluronan or hyaluronic acid (HA) is a biomaterial that has been introduced as an alternative approach to enhance wound healing and also used for oral ulcer treatment. The aim of this report is to present the treatment of drug-induced oral ulceration on maxillary mucosa with HA gel. 60-year-old male patient was referred to Department of Oral and Maxillofacial Surgery complaining of oral ulcerations during few weeks. He had received chemotherapy and radiotherapy in 2014 with the diagnosis of nasopharyngeal carcinoma, and he has accompanying systemic diseases such as; cardiological, neurological diseases and gout. He is medicated with Escitalopram (Cipralex® 20mg), Quetiapine (Seroquel® 100mg), Mirtazapine (Zestat® 15mg), Acetylsalicylic acid (Coraspin® 100mg), Ramipril-hydrochlorothiazide (Delix® 2.5mg), Theophylline anhydrous (Teokap Sr® 200mg), Colchicine (Colchicum Dispert® 0.5mg), Spironolactone (Aldactone® 100mg), Levothyroxine sodium (Levotiron® 50mg). He had painful oral ulceration on the right side of maxillary mucosa. The diagnosis was 'drug-induced oral ulceration' and HA oral gel (Aftamed® Oral gel) was prescribed 3 times a day for 2 weeks. Complete healing was achieved within 3 weeks without any side effect and discomfort. We suggest that HA oral gel is a potentially useful local drug which can be an alternative for management of drug-induced oral ulcerations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug-induced" title="drug-induced">drug-induced</a>, <a href="https://publications.waset.org/abstracts/search?q=hyaluronic%20acid" title=" hyaluronic acid"> hyaluronic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20ulceration" title=" oral ulceration"> oral ulceration</a>, <a href="https://publications.waset.org/abstracts/search?q=maxillary%20mucosa" title=" maxillary mucosa"> maxillary mucosa</a> </p> <a href="https://publications.waset.org/abstracts/89834/treatment-of-drug-induced-oral-ulceration-with-hyaluronic-acid-gel-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89834.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">268</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">132</span> One Way to Address the Complications of Dental Implantology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Predrag%20Kavaric">Predrag Kavaric</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20L.%20Jubic"> Vladimir L.

In anamnesis, we got information that his dental intervention was two years ago when he got dental implants but because of the coronavirus pandemic event, he didn’t finish the whole procedure. After two years, he decided that he will continue his work at his dentist, then his dentist noticed that there is no earlier inserted implant in the upper jaw on the right side. They do Panoramic X-ray and find that the implant is all in the maxillary sinus cavity. The flour of the maxilla was intact without any fistula on the place where the implant was inserted in the maxilla bone, After that initial diagnostic they sent the patient to maxillofacial surgery and otorhinolaryngology. We asked for a CT scan of paranasal sinuses, which confirmed the foreign body in the right maxillary sinus. The plan was that in general anesthesia we do FESS and try to find a foreign body in the maxillary sinus or in case of failure to do Caldwel Luc on that side. After preoperative preparation in GA, we do FESS. In inspection, we find small polyps and chronically changed mucosa of osteomeatal complex and right maxillary sinus. After removing polyps we did uncinectomy and medial maxillectomy. With Heuweiser Antrum grasping forceps after several attempts we managed to extract a foreign body from the bottom of the right maxillary sinus. On the first postoperative day we did detamponade, and then we discharge the patient from hospital. The Covid pandemic has contributed to the postponement of a large number of planned operations, which has resulted in various complications in the treatment of a number of patients. In this case, it happened that the implant was most likely rejected by the bone but in the direction of the maxillary sinus, which is not a common cause. On the other hand, the success was that less traumatic intervention was able to remove the foreign body from the maxillary sinus in which it was located. Since the sinus floor is free of bone defects, it can be continued relatively quickly with dental procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=x-ray" title="x-ray">x-ray</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=maxillar%20sinus" title=" maxillar sinus"> maxillar sinus</a>, <a href="https://publications.waset.org/abstracts/search?q=complication" title=" complication"> complication</a>, <a href="https://publications.waset.org/abstracts/search?q=fees" title=" fees"> fees</a> </p> <a href="https://publications.waset.org/abstracts/146688/one-way-to-address-the-complications-of-dental-implantology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146688.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">131</span> Impacted Maxillary Canines and Associated Dental Anomalies </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Athanasia%20Eirini%20Zarkadi">Athanasia Eirini Zarkadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Despoina%20Balli"> Despoina Balli</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Elpis%20Kolokitha"> Olga Elpis Kolokitha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Impacted maxillary canines are a frequent condition and a common reason for patients seeking orthodontic treatment. Their simultaneous presence with dental anomalies raises a question about their possible connection. The aim of this study was to investigate the association of maxillary impacted canines with dental anomalies. Materials and Methods: Files of 874 patients from an orthodontic private practice in Greece were evaluated for the presence of maxillary impacted canines. From this sample, a group of 97 patients (39 males and 58 females) with at least one impacted maxillary canine were selected and consisted of the study group (canine impaction group) of this study. This group was compared to a control group of 97 patients (42 males and 55 females) that was created by random selection from the initial sample without maxillary canine impaction. The impaction diagnosis was made from the panoramic radiographs and confirmed from the surgery. The association between maxillary canine impaction and dental anomalies was examined with the chi-square test. A classification tree was created to further investigate the relations between impaction and dental anomalies. The reproducibility of diagnoses was assessed by re-examining the records of 25 patients two weeks after the first examination. Results: The found associated anomalies were cone-shaped upper lateral incisors and infraocclusion of deciduous molars. There is a significant increase in the prevalence of 12,4% of distal displacement of the unerupted mandibular second premolar in the canine impaction group compared to the control group that was 7,2%. The classification tree showed that the presence of a cone-shaped maxillary lateral incisor gave rise to the probability of an impacted canine to 83,3%. Conclusions: The presence of cone-shaped maxillary lateral incisors and infraocclusion of deciduous molars can be considered valuable early risk indicators for maxillary canine impaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cone-shaped%20maxillary%20lateral%20incisors" title="cone-shaped maxillary lateral incisors">cone-shaped maxillary lateral incisors</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20anomalies" title=" dental anomalies"> dental anomalies</a>, <a href="https://publications.waset.org/abstracts/search?q=impacted%20canines" title=" impacted canines"> impacted canines</a>, <a href="https://publications.waset.org/abstracts/search?q=infraoccluded%20deciduous%20molars" title=" infraoccluded deciduous molars "> infraoccluded deciduous molars </a> </p> <a href="https://publications.waset.org/abstracts/133892/impacted-maxillary-canines-and-associated-dental-anomalies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133892.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">130</span> Gender Identification Using Digital Forensics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vinod%20C.%20Nayak">Vinod C.

Common treatment alternatives are distalization of adjacent teeth and fabrication of a conventional 3-unit fixed partial denture, a single implant supported crown restoration or a resin-bonded fixed partial denture. This case report describes the indication of a resin-bonded fixed partial denture, preparation of the abutment teeth and the prosthetic procedures. The technique described here represents a conservative, esthetically pleasing and rapid solution for the missing maxillary central incisor when implant placement and/or guided bone regeneration techniques are not feasible because of financial, social or time restrictions. In this case a 16 year-old female patient who lost her maxillary left central incisor six years ago in a bicycle accident applied to our clinic with a major complaint of her unaesthetic appearance associated with the loss of her maxillary left central incisor. Although there was an indication for orthodontic treatment because of the limited space at the traumatized area, the patient did not accept to receive any orthodontic procedure. That is why an implant supported restoration could not be an option for the narrow area. Therefore maryland bridge as a minimal invasive dental therapy was preferred as a retention appliance so the patient's aesthetic appearance was restored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryland%20bridge" title="Maryland bridge">Maryland bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20tooth%20restoration" title=" single tooth restoration"> single tooth restoration</a>, <a href="https://publications.waset.org/abstracts/search?q=aesthetics" title=" aesthetics"> aesthetics</a>, <a href="https://publications.waset.org/abstracts/search?q=maxillary%20central%20incisors" title=" maxillary central incisors"> maxillary central incisors</a> </p> <a href="https://publications.waset.org/abstracts/16882/maryland-restoration-of-anterior-tooth-loss-as-a-minimal-invasive-dentistry-an-alternative-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16882.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">360</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">128</span> The Morphological Picture of the Reinke's Oedema</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dins%20Sumerags">Dins Sumerags</a>, <a href="https://publications.waset.org/abstracts/search?q=Mara%20Pilmane"> Mara Pilmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Vita%20Konopecka"> Vita Konopecka</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunta%20Sumeraga"> Gunta Sumeraga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reinke’s oedema is a specific type of chronic laryngitis evolving only in smokers.

Methodology: A cross-sectional observational study was carried out on 80 Patients with biopsy-proven oral squamous cell carcinoma of buccal mucosa at Dow University of Health Sciences. All the study participants were treated with wide local excision of the primary tumor with elective neck dissection. Patients with prior head and neck malignancy or those with prior radiotherapy or chemotherapy were excluded from the study. Data was entered and analyzed on SPSS 21. Chi-squared test with 95% C.I and 80% power of the test was used to evaluate the relationship of tumor depth with cervical lymph nodes. Results: 50 participants were male, and 30 patients were female. 30 patients were in the age range of 20-40 years, 36 patients in the range of 40-60 years, while 14 patients were beyond age 60 years. Tumor size ranged from 0.3cm to 5cm with a mean of 2.03cm. Tumor depth ranged from 0.2cm to 5cm. 20% of the participants reported with tumor depth greater than 2.5cm, while 80% of patients reported with tumor depth less than 2.5cm. Out of 80 patients, 27 reported with negative lymph nodes, while 53 patients reported with positive lymph nodes. Conclusion: Our study concludes that relationship exists between the depth of primary tumor and cervical lymphadenopathy in squamous cell carcinoma of buccal mucosa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=squamous%20cell%20carcinoma" title="squamous cell carcinoma">squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20depth" title=" tumor depth"> tumor depth</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20lymphadenopathy" title=" cervical lymphadenopathy"> cervical lymphadenopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=buccal%20mucosa" title=" buccal mucosa"> buccal mucosa</a> </p> <a href="https://publications.waset.org/abstracts/85223/predictive-value-of-primary-tumor-depth-for-cervical-lymphadenopathy-in-squamous-cell-carcinoma-of-buccal-mucosa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">237</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">126</span> Potential Therapeutic Effect of Obestatin in Oral Mucositis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20Stempniewicz">Agnieszka Stempniewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Ceranowicz"> Piotr Ceranowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Wojciech%20Macyk"> Wojciech Macyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Cieszkowski"> Jakub Cieszkowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Beata%20Ku%C5%9Bnierz-Caba%C5%82a"> Beata Kuśnierz-Cabała</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Ga%C5%82%C4%85zka"> Katarzyna Gałązka</a>, <a href="https://publications.waset.org/abstracts/search?q=Zygmunt%20Warzecha"> Zygmunt Warzecha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: There are numerous strategies for the prevention or treatment of oral mucositis. However, their effectiveness is limited and does not correspond to expectations. Recent studies have shown that obestatin exhibits a protective effect and accelerates the healing of gastrointestinal mucosa. The aim of the present study was to examine the influence of obestatin administration on oral ulcers in rats. Methods: lingual ulcers were induced by the use of acetic acid. Rats were treated twice a day intraperitoneally with saline or obestatin(4, 8, or 16 nmol/kg/dose) for five days. The study determined: lingual mucosa morphology, cell proliferation, mucosal blood flow, and mucosal pro-inflammatory interleukin-1β level(IL-1β). Results: In animals without induction of oral ulcers, treatment with obestatin was without any effect. Obestatin administration in rats with lingual ulcers increased the healing rate of these ulcers. Obestatin given at the dose of 8 or 16 nmol/kg/dose caused the strongest and similar therapeutic effect. This result was associated with a significant increase in blood flow and cell proliferation in gingival mucosa, as well as a significant decrease in IL-1β level. Conclusions: Obestatin accelerates the healing of lingual ulcers in rats. This therapeutic effect is well-correlated with an increase in blood flow and cell proliferation in oral mucosa, as well as a decrease in pro-inflammatory IL-1β levels. Obestatin is a potentially useful candidate for the prevention and treatment of oral mucositis. Acknowledgment: Agnieszka Stempniewicz acknowledges the support of InterDokMed project no.

There are a number of methods that can be used to estimate the sex of human remains varying from visual assessments to metric analysis of sexually dimorphic traits. Teeth are one of the most durable physical elements in human body that can be used for this purpose. The present study investigated the utility of cervical measurements for sex estimation through discriminant analysis. The permanent molar teeth of 75 skeletons (28 females and 52 males) from Hasanlu site in North-western Iran were studied. Cervical mesiodistal and buccolingual measurements were taken from both maxillary and mandibular first and second molars. Discriminant analysis was used to evaluate the accuracy of each diameter in assessing sex. The results showed that males had statistically larger teeth than females for maxillary and mandibular molars and both measurements (P < 0.05). The range of classiﬁcation rate was from (75.7% to 85.5%) for the original and cross-validated data. The most dimorphic teeth were maxillary and mandibular second molars providing 85.5% and 83.3% correct classification rate respectively. The data generated from the present study suggested that cervical mesiodistal and buccolingual measurements of the molar teeth can be useful and reliable for sex estimation in Iranian archaeological populations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervical%20measurements" title="cervical measurements">cervical measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasanlu" title=" Hasanlu"> Hasanlu</a>, <a href="https://publications.waset.org/abstracts/search?q=premolars" title=" premolars"> premolars</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20estimation" title=" sex estimation "> sex estimation </a> </p> <a href="https://publications.waset.org/abstracts/48568/sex-estimation-using-cervical-measurements-of-molar-teeth-in-an-iranian-archaeological-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48568.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">124</span> Evaluation of the Golden Proportion and Golden Standard of Maxillary Anterior Teeth in Relation to Smile Attractiveness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwan%20Ahmed%20Swileh">Marwan Ahmed Swileh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amal%20Hussein%20Abuaffan"> Amal Hussein Abuaffan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: This study aimed to explore the existence of golden proportion (GP) between the widths of maxillary anterior teeth and golden standard (GS) for width to height ratio of maxillary central incisor in individuals with attractive and non-attractive smiles. Materials and methods: A total of 82 females were recruited and divided into 2 groups: attractive smile (n= 41) and non-attractive smile (n= 41). Frontal photographs were taken, scanned, and saved on a personal computer. The apparent mesiodistal width of each anterior tooth was measured. The data were analyzed using the appropriate statistical tests at p-value < 0.05. Results: Frequency of GP was very low among the total sample, and most proportions were higher than GP. No significant differences were found between both groups in relation to central-to-lateral ratio while significant differences were found in relation to canine-to-lateral ratio. Similarly, most proportions of width to height ratio were higher than GS. Difference between groups was significant for left side and for both sides (p < 0.05) but was not for right side (p > 0.05). Conclusion: Frequency of golden proportion was very low among the study population. Smile attractiveness is not related that much to the proportions between the teeth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=golden%20proportion" title="golden proportion">golden proportion</a>, <a href="https://publications.waset.org/abstracts/search?q=golden%20standard" title=" golden standard"> golden standard</a>, <a href="https://publications.waset.org/abstracts/search?q=attractive%20smile" title=" attractive smile"> attractive smile</a>, <a href="https://publications.waset.org/abstracts/search?q=esthetic" title=" esthetic"> esthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=anterior%20teeth" title=" anterior teeth"> anterior teeth</a> </p> <a href="https://publications.waset.org/abstracts/103992/evaluation-of-the-golden-proportion-and-golden-standard-of-maxillary-anterior-teeth-in-relation-to-smile-attractiveness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103992.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">123</span> Crossbite Unilateral Correction Using Transpalatal Arch with Extension Arm Modification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanifa%20Maryani%20Ahmad">Hanifa Maryani Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Muslim%20Yusuf"> Muslim Yusuf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Unilateral crossbite can be defined as an abnormal transverse relationship between the upper and lower teeth where the mandibular buccal cusp occluding to the maxillary buccal cusp and which involves only one side of the arch. This report describes the treatment of an adolescent female with Class III malocclussion unilateral crossbite resulting from a mildly constricted maxillary arch. The patient had a Class III skeletal relationship, Class III molar relationships, unilateral crossbite on the left side, and deviated midlines. Objectives: The treatment objectives were to correct the abnormal transverse relationship, achieve proper dental inclination, and correct the unilateral crossbites to improve the facial profile. Case management: The treatment protocol was using transpalatal arch with extension arm modification to expand the maxillary arch. Following the levelling and aligning stage of treatment, using a vertical loop while mandibular arch was expanded after getting an end to end relationship on the anterior side. Results: Corrections of the unilateral crossbite were achieved in 4 months. The treatment is still on process because the canines relationship were not corrected. Conclusions: This report highlights a treatment using transpalatal arch with extension arm modification that can be used to expand the transverse width of an arch to correct the discrepancy. Even though the treatment processes were still ongoing, the correction of the unilateral crossbite have been achieved in 4 months by only using the transpalatal arch. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crossbite%20unilateral" title="crossbite unilateral">crossbite unilateral</a>, <a href="https://publications.waset.org/abstracts/search?q=late%20growing" title=" late growing"> late growing</a>, <a href="https://publications.waset.org/abstracts/search?q=non-extraction" title=" non-extraction"> non-extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=transpalatal%20arch" title=" transpalatal arch"> transpalatal arch</a> </p> <a href="https://publications.waset.org/abstracts/80589/crossbite-unilateral-correction-using-transpalatal-arch-with-extension-arm-modification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80589.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">122</span> The Incidence of Maxillary Canine Ankylosis: A Single-Centre Analysis of 206 Canines Following Surgical Exposure and Orthodontic Alignment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidra%20Suleman">Sidra Suleman</a>, <a href="https://publications.waset.org/abstracts/search?q=Maliha%20Suleman"> Maliha Suleman</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinesh%20Shah"> Jinesh Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Maxillary canines play a crucial role in occlusion and aesthetics. Successful management of impacted canines requires early identification and intervention to prevent complications such as resorption of adjacent teeth and cystic changes. Although removal of the deciduous canine can encourage normal eruption of its successor, this is not always successful. Some patients may require surgical exposure and bonding of a gold chain to mobilise and align the canine, which can take up to 3 years. As this procedure has various risks, patients need to be appropriately consented to. Failure of such treatment commonly occurs due to inadequate anchorage or failure of the gold chain attachment, but in some cases, this is due to ankylosis. Aim: The aim of this study was to determine the incidence of ankylosis of unerupted maxillary ectopic canines following surgical exposure and orthodontic alignment at the Maxillofacial and Orthodontic Department, Royal Stoke University Hospital (RSUH), United Kingdom. Methodology: Patients treated from January 1, 2017, to December 31, 2019, were retrospectively studied. Electronic records with post-treatment follow-up at 3-6 months and 12-15 months were extracted and analysed. Patients were excluded based on three criteria, non-compliance with orthodontic treatment post-surgery, presence of canine transposition, and external orthodontic treatment. Sample: Overall, 159 suitable patients were selected from the 171 patients identified. Surgical exposure and gold chain bonding was carried out for a total of 206 maxillary canines, with the pattern of impaction being 159 (77.2 %) palatal, 46 (22.3%) buccal, and 1 (0.49%) in line of the arch. The sample consisted of 57 (35.8%) males and 102 (64.2%) females between the age range of 10 to 32 years, with the mean age being 15 years. The procedures were carried out under general anaesthesia for all but three patients, with two cases being repeats. Closed exposure was carried out for 189 (91.7%) canines. Results: The incidence of ankylosis from this study was 0.97%. In total, two patients had upper left canine ankylosis, which was identified at their 12-15 months orthodontic follow-up. Both patients were males, one having closed exposure at age 15 and the other having open exposure at age 19. Conclusions: Although this data shows that there is a low risk of ankylosis (0.97%), it highlights the difficulty in predicting which patients may be affected, and thus, a thorough pre-treatment assessment and careful observation during treatment is necessary. Future studies involving larger cohorts are warranted to further analyse factors affecting outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ankylosis" title="ankylosis">ankylosis</a>, <a href="https://publications.waset.org/abstracts/search?q=ectopic" title=" ectopic"> ectopic</a>, <a href="https://publications.waset.org/abstracts/search?q=maxillary%20canines" title=" maxillary canines"> maxillary canines</a>, <a href="https://publications.waset.org/abstracts/search?q=orthodontics" title=" orthodontics"> orthodontics</a> </p> <a href="https://publications.waset.org/abstracts/139035/the-incidence-of-maxillary-canine-ankylosis-a-single-centre-analysis-of-206-canines-following-surgical-exposure-and-orthodontic-alignment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139035.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">209</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">121</span> Morphological Process of Villi Detachment Assessed by Computer-Assisted 3D Reconstruction of Intestinal Crypt from Serial Ultrathin Sections of Rat Duodenum Mucosa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lise%20P.%20Lab%C3%A9jof">Lise P.

It was tested a morphological method of 3d reconstruction using micrographs of serial sections of rat duodenum. We used hundreds of sections of each specimen of duodenum placed on glass slides and examined under a light microscope. Those containing the detachment, approximately a dozen, were chosen for observation under a transmission electron microscope (TEM). Each of these sections was glued on a block of epon resin and recut into a hundred of 60 nm-thick sections. Ribbons of these ultrathin sections were distributed on a series of copper grids in the same order of appearance than during the process of microstomia. They were then stained by solutions of uranyl and lead salts and observed under a TEM. The sections were pictured and the electron micrographs showing signs of cells detachment were transferred into two softwares, ImageJ to align the cellular structures and Reconstruct to realize the 3d reconstruction. It has been detected epithelial cells that exhibited all signs of programmed cell death and localized at the villus-crypt junction. Their nucleus was irregular in shape with a condensed chromatin in clumps. Their cytoplasm was darker than that of neighboring cells, containing many swollen mitochondria. In some places of the sections, we could see intercellular spaces enlarged by the presence of shrunk cells which displayed a plasma membrane with an irregular shape in thermowell as if the cell interdigitations would distant from each other. The three-dimensional reconstruction of the crypts has allowed observe gradual loss of intercellular contacts of crypt cells in the longitudinal plan of the duodenal mucosa. In the transverse direction, there was a gradual increase of the intercellular space as if these cells moved away from one another. This observation allows assume that the gradual remoteness of the cells at the villus-crypt junction is the beginning of the mucosa detachment. Thus, the shrinking of cells due to apoptosis is the way that they detach from the mucosa and progressively the villi also. These results are in agreement with our initial hypothesis and thus have demonstrated that the villi become detached from the mucosa at the villus-crypt junction by the programmed cell death process. This type of loss of entire villus helps explain the rapid denudation of the intestinal mucosa in case of irradiation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3dr" title="3dr">3dr</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20electron%20microscopy" title=" transmission electron microscopy"> transmission electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=ionizing%20radiations" title=" ionizing radiations"> ionizing radiations</a>, <a href="https://publications.waset.org/abstracts/search?q=rat%20small%20intestine" title=" rat small intestine"> rat small intestine</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a> </p> <a href="https://publications.waset.org/abstracts/41139/morphological-process-of-villi-detachment-assessed-by-computer-assisted-3d-reconstruction-of-intestinal-crypt-from-serial-ultrathin-sections-of-rat-duodenum-mucosa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41139.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">120</span> Esthetic Rehabilitation of White and Brown Spot Lesions with Ceramic Veneers: A Clinical Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rania%20E.%20Ramadan">Rania E.

However, if there is any imperfection seen by both the dentist and the patient, it is considered as an unesthetic like white and/or brown spot lesions. Many patients nowadays have been concerned about dental esthetics. Esthetic rehabilitation of anterior teeth and even maxillary premolars aid a lot in patients’ satisfaction of their smile consequently, gaining positive psychological impact for the patients. Many cases need esthetic rehabilitation such as diastema closure, spaced teeth and masking discolored teeth. Dental fluorosis and enamel hypo calcification can be presented as white and/or brown spot lesions. There are many treatment options for the management of these spotted teeth. Treatment options range from bleaching, microabrasion, direct composite restorations, porcelain veneers, and complete coverage crowns. The selection of certain options depends on many factors: the patient’s age, socioeconomic status and the severity of the lesion. In this clinical report, a 22-year-old male patient has been presented to the Department of Prosthodontics in Alexandria University, Egypt. His chief complaint was, “I was unpleased by white and brown spots in my teeth and I want to close the space between the two maxillary central.” Upon medical history, clinical examination, diagnostic photographs, and digital smile design by Exocad software, lithium disilicate veneers were chosen as the treatment of choice in maxillary anterior and first premolars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flourosis" title="flourosis">flourosis</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramic%20veneers" title=" ceramic veneers"> ceramic veneers</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20report" title=" case report"> case report</a>, <a href="https://publications.waset.org/abstracts/search?q=diastema%20closure" title=" diastema closure"> diastema closure</a> </p> <a href="https://publications.waset.org/abstracts/147146/esthetic-rehabilitation-of-white-and-brown-spot-lesions-with-ceramic-veneers-a-clinical-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147146.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">119</span> Prevalence of Dens Evaginatus in Adolescent Population of Melaka: A Retrospective Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Preethy%20Mary%20Donald">Preethy Mary Donald</a>, <a href="https://publications.waset.org/abstracts/search?q=Renjith%20George%20Pallivathukal"> Renjith George Pallivathukal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dens evaginatus (DE) is a rare developmental anomaly characterized by a slender enamel-covered tubercle which projects from the occlusal surface of an otherwise normal premolar.

Maxillary reconstruction using fibula osteocutaneous flaps in situation requiring orbital floor, orbital wall, palatal defects, and external skin, all at the same time require special planning and multiple osteotomies. We tried to improvise our reconstruction using multiple osteotomies and skin paddle designs for fibula and Flexor Hallucis Longus Muscle. This study aims at discussing the planning and outcome in complex maxillary reconstructions using fibula flaps and soft tissue flaps with or without bone grafts. Material and Methods: From 2011 to 2017 a total of 129 Free fibula flaps were done, 67 required two or more struts, 164 Anterolateral Thigh Flaps, 11 Deep Inferior Epigastric Artery perforator flaps and 3 vertical rectus abdominis muscle flaps with iliac crest bone graft. The age range was 2 to 70 years. The reconstruction was evaluated based on the post-operative rehabilitation including orbital support (prevention of diplopia), oral diet, speech and cosmetic appearance. Results: The follow- up is from 5 years to 1 year. In this series, we observed that the common complications were the de-vascularisation of most distal segment of osteotomised fibula and native skin necrosis. Commonest area of breakdown is the medial canthal region. Plate exposure occurs most commonly at the pyriform sinus. There was extrusion of one non-vascularized bone graft. All these complications were noticed post-radiotherapy. Conclusions: The use of free fibula osteocutaneous flap gives very good results when only alveolar reconstruction is required. The reconstruction of orbital floor with extensive skin loss with post operative radiotherapy has maximum complication rate in long term follow up. A soft tissue flap with non vascularized bone graft may be the best option in such cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maxilla%20reconstruction" title="maxilla reconstruction">maxilla reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=fibula%20maxilla" title=" fibula maxilla"> fibula maxilla</a>, <a href="https://publications.waset.org/abstracts/search?q=post%20cancer%20maxillary%20reconstruction" title=" post cancer maxillary reconstruction"> post cancer maxillary reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/110980/reconstruction-of-complex-post-oncologic-maxillectomy-defects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110980.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">117</span> The Role of Rapid Maxillary Expansion in Managing Obstructive Sleep Apnea in Children: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suleman%20Maliha">Suleman Maliha</a>, <a href="https://publications.waset.org/abstracts/search?q=Suleman%20Sidra"> Suleman Sidra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Obstructive sleep apnea (OSA) is a sleep disorder that can result in behavioral and psychomotor impairments in children. The classical treatment modalities for OSA have been continuous positive airway pressure and adenotonsillectomy. However, orthodontic intervention through rapid maxillary expansion (RME) has also been commonly used to manage skeletal transverse maxillary discrepancies. Aim and objectives: The aim of this study is to determine the efficacy of rapid maxillary expansion in paediatric patients with obstructive sleep apnea by assessing pre and post-treatment mean apnea-hypopnea index (AHI) and oxygen saturations. Methodology: Literature was identified through a rigorous search of the Embase, Pubmed, and CINAHL databases. Articles published from 2012 onwards were selected. The inclusion criteria consisted of patients aged 18 years and under with no systemic disease, adenotonsillar surgery, or hypertrophy who are undergoing RME with AHI measurements before and after treatment. In total, six suitable papers were identified. Results: Three studies assessed patients pre and post-RME at 12 months. The first study consisted of 15 patients with an average age of 7.5 years. Following treatment, they found that RME resulted in both higher oxygen saturations (+ 5.3%) and improved AHI (- 4.2 events). The second study assessed 11 patients aged 5–8 years and also noted improvements, with mean AHI reduction from 6.1 to 2.4 and oxygen saturations increasing from 93.1% to 96.8%. The third study reviewed 14 patients aged 6–9 years and similarly found an AHI reduction from 5.7 to 4.4 and an oxygen saturation increase from 89.8% to 95.5%. All modifications noted in these studies were statistically significant. A long-term study reviewed 23 patients aged 6–12 years post-RME treatment on an annual basis for 12 years. They found that the mean AHI reduced from 12.2 to 0.4, with improved oxygen saturations from 78.9% to 95.1%. Another study assessed 19 patients aged 9-12 years at two months into RME and four months post-treatment. Improvements were also noted at both stages, with an overall reduction of the mean AHI from 16.3 to 0.8 and an overall increase in oxygen saturations from 77.9% to 95.4%. The final study assessed 26 children aged 7-11 years on completion of individual treatment and found an AHI reduction from 6.9 to 5.3. However, the oxygen saturation remained stagnant at 96.0%, but this was not clinically significant. Conclusion: Overall, the current evidence suggests that RME is a promising treatment option for paediatric patients with OSA. It can provide efficient and conservative treatment; however, early diagnosis is crucial. As there are various factors that could be contributing to OSA, it is important that each case is treated on its individual merits. Going forward, there is a need for more randomized control trials with larger cohorts being studied. Research into the long-term effects of RME and potential relapse amongst cases would also be useful. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=orthodontics" title="orthodontics">orthodontics</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20apnea" title=" sleep apnea"> sleep apnea</a>, <a href="https://publications.waset.org/abstracts/search?q=maxillary%20expansion" title=" maxillary expansion"> maxillary expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=review" title=" review"> review</a> </p> <a href="https://publications.waset.org/abstracts/157849/the-role-of-rapid-maxillary-expansion-in-managing-obstructive-sleep-apnea-in-children-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157849.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">116</span> Modification of Hyrax Expansion Screw to Be Used as an Intro-Oral Distractor for Anterior Maxillary Distraction in a Patient with Cleft Lip and Palate: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ananya%20Hazare">Ananya Hazare</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjit%20Kamble"> Ranjit Kamble</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Patients with Cleft lip and palate (CL/P) can present with a maxillary retrution after cleft repair. Anterior Maxillary distraction osteogenesis (AMD) is a technique that provides simultaneous skeletal advancement and expansion of the soft tissues related to an anterior segment of the maxilla. This case presented is a case of AMD. The advantage of this technique is that the occlusion in the posterior segment can be maintained, and only the segment in cross bite is advanced for correction of the midfacial deficiency. The other alternative treatment is anterior movement by a Lefort 1 osteotomy. When a Lefort 1 osteotomy is compared with the Distraction osteogenesis or AMD, the disadvantages of the Le Fort 1 include a higher risk of morbidity, requirement of fixation, relapse tendency and unexpected changes in the nasal form. These complications were eliminated by AMD technique. This was followed by placement of the implant in the bone formed after AMD. Hence complete surgical, orthodontic and prosthodontics rehabilitation of the patient was done by an interdisciplinary approach. Methods: Patient presented with repaired UCL/P of the right side with midfacial retrusion. Intro-oral examination revealed a good occlusion in the posterior arch and anterior Crossbite from canine to canine. Patient's both maxillary lateral incisors were missing. The lower arch was well aligned with all teeth present. The study models when scored according to GOSLON yardstick received a score of 4. After pre-surgical orthodontic phase was completed an intraoral distractor was fabricated by modification of HYRAX expansion screw. After surgery, low subapical osteotomy cuts were placed and the distractor was fixed. The latency period of 5 days was observed after which the distraction was started. Distraction was done at a rate of 1 mm/day with a rhythm of 0.5mm in morning and 0.5mm in the evening. The total distraction of 12 mm was done. After a consolidation period, the distractor was removed, and retention by a removable partial denture was given. Radiographic examination confirmed mature bone formation in the distracted segment. Implants were placed and allowed to osseointegrate for approximately 4 months and were then loaded with abutments. Results: Total distraction done was 12mm and after relapse it was 8mm. After consolidation phase the radiographic examination revealed a B2 quality of bone according to the Misch's classification and sufficient height from the maxillary sinus. These findings were indicative for placement of implants in the distracted bone formed in premolar region. Implants were placed and after radiographic evidence of osseointegration was seen they were loaded with abutments. Thus resulting in a complete rehabilitation of a cleft patient by an interdisciplinary approach. Conclusion: Anterior maxillary distraction can be used as an alternative method instead of complete distraction osteogenesis or Lefort 1 advancement of maxilla in cases where the advancement needed is minimum. Use of HYRAX expansion screw modified as intra-oral distractor can be used in such cases, which significantly reduces the cost of treatment, as expensive distractors are not used. This technique is very useful and efficient in countries like India where the patient cannot afford expensive treatment options. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cleft%20lip%20and%20palate" title="cleft lip and palate">cleft lip and palate</a>, <a href="https://publications.waset.org/abstracts/search?q=distraction%20osteogenesis" title=" distraction osteogenesis"> distraction osteogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=anterior%20maxillary%20distraction" title=" anterior maxillary distraction"> anterior maxillary distraction</a>, <a href="https://publications.waset.org/abstracts/search?q=orthodontics%20and%20dentofacial%20orthopaedics" title=" orthodontics and dentofacial orthopaedics"> orthodontics and dentofacial orthopaedics</a>, <a href="https://publications.waset.org/abstracts/search?q=hyrax%20expansion%20screw%20modification" title=" hyrax expansion screw modification"> hyrax expansion screw modification</a> </p> <a href="https://publications.waset.org/abstracts/54302/modification-of-hyrax-expansion-screw-to-be-used-as-an-intro-oral-distractor-for-anterior-maxillary-distraction-in-a-patient-with-cleft-lip-and-palate-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54302.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">256</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">115</span> Nano-emulsion/Nano-suspension as Precursors for Oral Dissolvable Film to Enhance Bioavalabilty for Poor-water Solubility Drugs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuan%20Yang">Yuan Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Mickey%20Lam"> Mickey Lam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oral dissolvable films have been considered as a unique alternative approach to conventional oral dosage forms. The films could be administrated via the gastrointestinal tract as conventional dosages or through sublingual/buccal mucosa membranes, which could enhance drug bioavailability by avoiding the first-pass effect and improving permeability due to high blood flow and lymphatic circulation. This work has described a state-of-art technic using nano-emulsion/nano-suspension as a precursor for the film to enhance the bioavailability of BCS class II drugs. The drug molecules are consequentially processed through the emulsification, gelation, and film-casting processes. The gelation process is critical to stabilizing the nano-emulsion for the film-casting as well as controlling the drug release process. Furthermore, the size of the nanoparticle on the film has a strong correlation with the size of the micelles in the precursor and the condition of the gelation process. It has been discovered that nanoparticle from 200 nm to 300 nm has shown the highest permeability for sublingual administration. In one example shown in work, the bioavailability of a low solubilize drug has been increased from 10% to 24% via sublingual administration of the film. The increasing of the bioavailability was thought to be associated with the enhancement of the diffusion process of the drug in the saliva layer above the mucosa membrane and the fact that the presents of the emulsifier help lose the rigid junction of the mucosa cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oral%20dissolvable%20film" title="oral dissolvable film">oral dissolvable film</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-suspension" title=" nano-suspension"> nano-suspension</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-emulsion" title=" nano-emulsion"> nano-emulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=bioavailability" title=" bioavailability"> bioavailability</a> </p> <a href="https://publications.waset.org/abstracts/142588/nano-emulsionnano-suspension-as-precursors-for-oral-dissolvable-film-to-enhance-bioavalabilty-for-poor-water-solubility-drugs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142588.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">114</span> Aesthetic Modification with Combined Orthognathic Surgery and Closed Rhinoplasty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Marano">Alessandro Marano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: The author describes the aesthetic modification using orthognathic surgery and closed rhinoplasty. Methods: Series of case study. After orthognathic surgery we can observe a dramatical change of aesthetic especially in the mid-face and nose projection. The advancement of maxillary bone through Le Fort I osteotomy will change the nasal tip projection and lips roundness; combining orthognathic surgery with closed approach rhinoplasty will manage both function and aesthetic of all mid face district. Results: Combining Le Fort I osteotomy with closed approach rhinoplasty resulted in good objective results with high patient satisfaction. Le Fort I osteotomy will increase projection of mid face and the closed approach rhinoplasty will modify the nasal shape to be more harmonic with the new maxillary district. The scars are not visible because hidden inside the mouth and nose. Conclusions: The orthognathic surgery combined with closed approach rhinoplasty are very effective for changing the aesthetic of the mid face. The results illustrate the difference between the use of orthognathic surgery only and to use it in association of closed approach rhinoplasty. Using both will allow to obtain a long lasting and pleasing results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=orthognathic" title="orthognathic">orthognathic</a>, <a href="https://publications.waset.org/abstracts/search?q=rhinoplasty" title=" rhinoplasty"> rhinoplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=aesthetic" title=" aesthetic"> aesthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=face" title=" face"> face</a> </p> <a href="https://publications.waset.org/abstracts/149677/aesthetic-modification-with-combined-orthognathic-surgery-and-closed-rhinoplasty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149677.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">100</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">113</span> Role of Pulp Volume Method in Assessment of Age and Gender in Lucknow, India, an Observational Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anurag%20Tripathi">Anurag Tripathi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanad%20Khandelwal"> Sanad Khandelwal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Age and gender determination are required in forensic for victim identification. There is secondary dentine deposition throughout life, resulting in decreased pulp volume and size. Evaluation of pulp volume using Cone Beam Computed Tomography (CBCT)is a noninvasive method to evaluate the age and gender of an individual. The study was done to evaluate the efficacy of pulp volume method in the determination of age and gender.Aims/Objectives: The study was conducted to estimate age and determine sex by measuring tooth pulp volume with the help of CBCT. An observational study of one year duration on CBCT data of individuals was conducted in Lucknow. Maxillary central incisors (CI) and maxillary canine (C) of the randomly selected samples were assessed for measurement of pulp volume using a software. Statistical analysis: Chi Square Test, Arithmetic Mean, Standard deviation, Pearson’s Correlation, Linear & Logistic regression analysis. Results: The CBCT data of Ninety individuals with age range between 18-70 years was evaluated for pulp volume of central incisor and canine (CI & C). The Pearson correlation coefficient between the tooth pulp volume (CI & C) and chronological age suggested that pulp volume decreased with age. The validation of the equations for sex determination showed higher prediction accuracy for CI (56.70%) and lower for C (53.30%).Conclusion: Pulp volume obtained from CBCT is a reliable indicator for age estimation and gender prediction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic" title="forensic">forensic</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20age" title=" dental age"> dental age</a>, <a href="https://publications.waset.org/abstracts/search?q=pulp%20volume" title=" pulp volume"> pulp volume</a>, <a href="https://publications.waset.org/abstracts/search?q=cone%20beam%20computed%20tomography" title=" cone beam computed tomography"> cone beam computed tomography</a> </p> <a href="https://publications.waset.org/abstracts/157795/role-of-pulp-volume-method-in-assessment-of-age-and-gender-in-lucknow-india-an-observational-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157795.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">112</span> The Prevalence of Intubation Induced Dental Complications among Hospitalized Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dorsa%20Rahi">Dorsa Rahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arghavan%20Tonkanbonbi"> Arghavan Tonkanbonbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Soheila%20Manifar"> Soheila Manifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Jafvarnejad"> Behzad Jafvarnejad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Aim: Intraoral manipulation is performed during endotracheal intubation for general anesthesia, which can traumatize the soft and hard tissue in the oral cavity and cause postoperative pain and discomfort. Dental trauma is the most common complication of intubation. This study aimed to assess the prevalence of dental complications due to intubation in patients hospitalized in Imam Khomeini Hospital during 2018-2019. Materials and Methods: A total of 805 patients presenting to the Cancer Institute of Imam Khomeini Hospital for preoperative anesthesia consultation were randomly enrolled. A dentist interviewed the patients and performed a comprehensive clinical oral examination preoperatively. The patients underwent clinical oral examination by another dentist postoperatively. Results: No significant correlation was found between dental trauma (tooth fracture, tooth mobility, or soft tissue injury) after intubation with the age or gender of patients. According to the Wilcoxon test and McNemar-Bowker Test, the rate of mobility before the intubation was significantly different from that after the intubation (P=0.000). Maxillary central incisors, maxillary left canine and mandibular right and left central incisors had the highest rate of fracture. Conclusion: Mobile teeth before the intubation are at higher risk of avulsion and aspiration during the procedure. Patients with primary temporomandibular joint disorders are more susceptible to post-intubation trismus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oral%20trauma" title="oral trauma">oral trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20trauma" title=" dental trauma"> dental trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=intubation" title=" intubation"> intubation</a>, <a href="https://publications.waset.org/abstracts/search?q=anesthesia" title=" anesthesia "> anesthesia </a> </p> <a href="https://publications.waset.org/abstracts/134016/the-prevalence-of-intubation-induced-dental-complications-among-hospitalized-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134016.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">111</span> Influence of Pediococcus Pentasaceus Isolate “Dadih” (Buffalo Milk Fermended in Bamboo) the Bowel Frequence, Secretory Immunoglobulin a Level and Height of Ileum Villi of the Mice EPEC Induced Diarrhea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Endang%20Purwati%20Rahayuningsih">Endang Purwati Rahayuningsih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is Enteropathogenic Eschericia coli O157 (EPEC) is one of the pathogen that can cause inflamation and damage intestinal mucosa, which is leading diarrhea. Inflamation in the intestinal mucosa proved by the presence of secretory Immunoglobulin A (sIgA) on the feces. Isolate dadih is Pediococcus pentosaceus (P. pentosaceus) as a probiotic lactic acid bacteria (LAB) is very usefull to improve sIgA and intestinal mucosa. The objective, to determine the dose and duration administration of P. pentosaceus for bowel frequence, sIgA level and height of illeum villi in mice EPEC-induced diarrhea. Method, using Complete Randomized design studies in mice EPEC-induced diarrhea. Mice was classified into 2 factors. A factor (dose of probiotic) and B factor (duration of probiotic observation) consisted of 0 hour, 12 hours, 24 hours and 36 hours. A factor consisted of negative control, positive control (mice induced by EPEC) and 3 different dose experimental mice. The results were a very significant interaction between dose and duration administration of P. pentosaceus.

It can also exhibit oral lesions with simultaneous associated skin lesions. The MD involving the oral mucosa commonly presents with signs such as ulcers, vesicles and bullae. The unique environment of the oral cavity may modify these signs of the disease, thereby making the clinical diagnosis an arduous task. In addition to the unique environment of oral cavity, the overlapping of the signs of various mucocutaneous disorders, also makes the clinical diagnosis more intricate. The aim of this review is to present the oral signs of dermatological disorders having common oral involvement and emphasize their importance in early detection of the systemic disorders. The aim is also to highlight the necessity of oral examination by a dermatologist while examining the skin lesions. Prior to the oral examination, it must be imperative for the dermatologists and the dental clinicians to have the knowledge of oral anatomy. It is also important to know the impact of various diseases on oral mucosa, and the characteristic features of various oral mucocutaneous lesions. An initial clinical oral examination is may help in the early diagnosis of the MD. Failure to identify the oral manifestations may reduce the likelihood of early treatment and lead to more serious problems.

The graft has gained its popularity due to its excellent short and long-term results, easy harvesting as well as its ability in withstanding wet environments. However, although Buccal mucosal grafts are an excellent option, it is not free of complications, potential intraoral complications are bleeding, pain, swelling, injury to the nerve resulting in numbness, lip deviation or retraction. Objectives: The current study aims to evaluate the intraoral complications of buccal mucosa grafts harvested from one cheek, and used in Augmentation Urethroplasty. Methodology: The study was conducted retrospectively using the medical records of patients who underwent open augmentation urethroplasty with a buccal mucosa graft at King Khalid University Hospital, Saudi Arabia. Data collection of demographics included the type of graft used, presence or absence of strictures and its etiological factors. Pre-operative and post-operative evaluations were carried out on the subjects including the medical history, physical examination, uroflowmetry, retrograde urethrography, voiding cystourethrography and urine cultures were also noted. Further, the quality of life and complications of the procedure including the presence or occurrence of bleeding within 3-days post-procedure, the severity of pain, oral swelling after grafting, length of return to normal daily diet, painful surgical site, intake of painkillers, presence or absence of speech disturbance, numbness in the cheeks and lips were documented. Results: Thirty-two male subjects with ages ranging from 15 years to 72 years were included in the current study. Following the procedure, a hundred percent of the subjects returned to their normal daily diet by the sixth postoperative day. Further, the majority of the patients reported experiencing mild pain accounting for 61.3%, and 90.3% of the subjects reported using painkillers to control the pain. Surgical wound Pain was reportedly more common at the perineal site as 48.4% of the subjects experienced it; on the other hand, 41.9% of the patients experienced pain in the oral mucosa. The presence of speech disorders, as assessed through medical history, was found to be present in 3.2% of patients. The presence of numbness in the cheeks and lips was found in 3.2% of patients. Other complications such as parotid duct injury, delayed wound healing, non-healing wound and suture granuloma were rare as 90.3% of the subjects denied experiencing any of them, there were nonetheless reports of parotid duct injury by 6.5% of the patients, and non-healing wound by the 3.2% of patients. Conclusion: Buccal Mucosa Graft in Augmentation Urethroplasty is an ideal source of allograft, although not entirely painless; it is considerably safe with minimal intra-oral complication and undetectable strain on the patients’ quality of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=augmentation" title="augmentation">augmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=buccal" title=" buccal"> buccal</a>, <a href="https://publications.waset.org/abstracts/search?q=graft" title=" graft"> graft</a>, <a href="https://publications.waset.org/abstracts/search?q=oral" title=" oral"> oral</a> </p> <a href="https://publications.waset.org/abstracts/120523/evaluation-of-intraoral-complications-of-buccal-mucosa-graft-in-augmentation-urethroplasty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120523.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">179</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">108</span> A Cephalometric Superimposition of a Skeletal Class III Orthognathic Patient on Nasion-Sella Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Albert%20Suryaprawira">Albert Suryaprawira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Nasion-Sella Line (NSL) has been used for several years as a reference line in longitudinal growth study. Therefore this line is considered to be stable not only to evaluate treatment outcome and to predict relapse possibility but also to manage prognosis. This is a radiographic superimposition of an adult male aged 19 years who complained of difficulty in aesthetic, talking and chewing. Patient has a midface hypoplasia profile (concave). He was diagnosed to have a severe Skeletal Class III with Class III malocclusion, increased lower vertical height, and an anterior open bite. A pre-treatment cephalometric radiograph was taken to analyse the skeletal problem and to measure the amount of bone movement and the prediction soft tissue response. A panoramic radiograph was also taken to analyse bone quality, bone abnormality, third molar impaction, etc. Before the surgery, a pre-surgical cephalometric radiograph was taken to re-evaluate the plan and to settle the final amount of bone cut. After the surgery, a post-surgical cephalometric radiograph was taken to confirm the result with the plan. The superimposition using NSL as a reference line between those radiographs was performed to analyse the outcome. It is important to describe the amount of hard and soft tissue movement and to predict the possibility of relapse after the surgery. The patient also needs to understand all the surgical plan, outcome and relapse prevention. The surgical management included maxillary impaction and advancement of Le Fort I osteotomy. The evaluation using NSL as a reference was a very useful method in determining the outcome and prognosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasion-Sella%20Line" title="Nasion-Sella Line">Nasion-Sella Line</a>, <a href="https://publications.waset.org/abstracts/search?q=midface%20hypoplasia" title=" midface hypoplasia"> midface hypoplasia</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Fort%201" title=" Le Fort 1"> Le Fort 1</a>, <a href="https://publications.waset.org/abstracts/search?q=maxillary%20advancement" title=" maxillary advancement"> maxillary advancement</a> </p> <a href="https://publications.waset.org/abstracts/87943/a-cephalometric-superimposition-of-a-skeletal-class-iii-orthognathic-patient-on-nasion-sella-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87943.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">107</span> Detection of Oral Mucosal Lesions in Cutaneous Psoriatic Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rania%20A.%20R.%20Soudan">Rania A.

It may affect the mucous membranes. The presence of oral mucosal lesions has been a subject of controversy. The aim: To determine possible association between oral mucosal lesions and psoriasis, and to correlate the same with different types of psoriasis and severity of the disease. Materials and Methods: The oral mucosa was clinically examined in 100 randomly selected Syrian psoriatic patients presented to the Dermatological Diseases Hospital in Damascus University, Syria (February 2009 - December 2010), and in 100 matched controls. PASI index was used to evaluate the disease severity. Chi-square and Student t-test were used to compare differences between groups. Results: Oral mucosal lesions were observed in 72% of the psoriasis cases, while 46% of the control group’s subjects had oral lesions. Fissured tongue, geographic tongue, and red lesions were detected in 36%, 25%, and 7% of the examined psoriatics, respectively. These lesions were significantly more frequent in the psoriatics than in the controls. A correlation was found between furred tongue and the age of the psoriasis patients. However, an association was observed for fissured tongue, furred tongue with the severity of the disease, and for fissured tongue, white lesions, cheilitis with nail involvement. However, no correlation with the psoriasis types was recorded. Conclusion: Some oral mucosal lesions were associated with psoriasis, so these lesions may be considered as oral manifestations of this disease, and should be taken into account in new studies as possible predictors or markers of this dermatitis. Further studies are recommended to confirm these oral manifestations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=psoriasis" title="psoriasis">psoriasis</a>, <a href="https://publications.waset.org/abstracts/search?q=tongue" title=" tongue"> tongue</a>, <a href="https://publications.waset.org/abstracts/search?q=mucosa" title=" mucosa"> mucosa</a>, <a href="https://publications.waset.org/abstracts/search?q=lesions" title=" lesions"> lesions</a> </p> <a href="https://publications.waset.org/abstracts/6154/detection-of-oral-mucosal-lesions-in-cutaneous-psoriatic-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6154.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">106</span> Correlation between Cephalometric Measurements and Visual Perception of Facial Profile in Skeletal Type II Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Choki">Choki</a>, <a href="https://publications.waset.org/abstracts/search?q=Supatchai%20Boonpratham"> Supatchai Boonpratham</a>, <a href="https://publications.waset.org/abstracts/search?q=Suwannee%20Luppanapornlarp"> Suwannee Luppanapornlarp</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to find a correlation between cephalometric measurements and visual perception of facial profile in skeletal type II patients. In this study, 250 lateral cephalograms of female patients from age, 20 to 22 years were analyzed. The profile outlines of all the samples were hand traced and transformed into silhouettes by the principal investigator. Profile ratings were done by 9 orthodontists on Visual Analogue Scale from score one to ten (increasing level of convexity). 37 hard issue and soft tissue cephalometric measurements were analyzed by the principal investigator. All the measurements were repeated after 2 weeks interval for error assessment. At last, the rankings of visual perceptions were correlated with cephalometric measurements using Spearman correlation coefficient (P < 0.05). The results show that the increase in facial convexity was correlated with higher values of ANB (A point, nasion and B point), AF-BF (distance from A point to B point in mm), L1-NB (distance from lower incisor to NB line in mm), anterior maxillary alveolar height, posterior maxillary alveolar height, overjet, H angle hard tissue, H angle soft tissue and lower lip to E plane (absolute correlation values from 0.277 to 0.711). In contrast, the increase in facial convexity was correlated with lower values of Pg. to N perpendicular and Pg. to NB (mm) (absolute correlation value -0.302 and -0.294 respectively). From the soft tissue measurements, H angles had a higher correlation with visual perception than facial contour angle, nasolabial angle, and lower lip to E plane. In conclusion, the findings of this study indicated that the correlation of cephalometric measurements with visual perception was less than expected. Only 29% of cephalometric measurements had a significant correlation with visual perception. Therefore, diagnosis based solely on cephalometric analysis can result in failure to meet the patient’s esthetic expectation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cephalometric%20measurements" title="cephalometric measurements">cephalometric measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=facial%20profile" title=" facial profile"> facial profile</a>, <a href="https://publications.waset.org/abstracts/search?q=skeletal%20type%20II" title=" skeletal type II"> skeletal type II</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20perception" title=" visual perception"> visual perception</a> </p> <a href="https://publications.waset.org/abstracts/109828/correlation-between-cephalometric-measurements-and-visual-perception-of-facial-profile-in-skeletal-type-ii-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109828.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">105</span> Pathological Observations of Intestinal Coccidiosis in Camel (Camelus dromedarius)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhilasha%20Dadhich">Abhilasha Dadhich</a>, <a href="https://publications.waset.org/abstracts/search?q=Manisha%20Mathur"> Manisha Mathur</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar"> Sanjay Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hemant%20Dadhich"> Hemant Dadhich</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The camel (Camelus dromedarius) is an important animal component of the fragile desert eco-system of India. Apart from others, impaired milk and meat production decrease in performance and even death are some of the major consequences of parasitic disease like coccidiosis in camel. Coccidiosis which is an acute invasion and destruction of intestinal mucosa by protozoa of the genera Eimeria or isospora spp. Post-Mortem examinations of 5 carcasses of dromedary of different age groups aged from 2 to 5 years were conducted. The history indicated that the camels were suffering from diarrhoea, dysentery, pyrexia, inappetence, weight loss, and emaciation. Post mortem examinations showed macroscopic and microscopic alterations in the small intestine, particularly in jejunum and ileum regions. The mucosae were congested, and haemorrhagic on which there were numerous whitish-grey nodular foci were observed. The affected intestinal tissue specimens were preserved in 10% formal saline and processed mechanically for paraffin embedding by acetone and benzene technique. The sections were stained with haematoxylin and eosin method of staining for histopathological examinations. Histologically, typical lesions such as congestion and haemorrhages were present. The intestinal villi were oedematous; mucosa degenerated and desquamated, along with infiltration of eosinophils and macrophages. Crypts of lieberkuhn were obliterated due to presence of schizonts in lamina propria. Older camels served as the source of spread of coccidial infection and were also predisposed to secondary infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=camel" title="camel">camel</a>, <a href="https://publications.waset.org/abstracts/search?q=coccidiosis" title=" coccidiosis"> coccidiosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Eimeria" title=" Eimeria"> Eimeria</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a> </p> <a href="https://publications.waset.org/abstracts/80532/pathological-observations-of-intestinal-coccidiosis-in-camel-camelus-dromedarius" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80532.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">104</span> Hyaluronic Acid as Potential Excipient for Buccal Delivery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Flavia%20Laffleur">Flavia Laffleur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Summary: Biomaterials have gained immense interest in the pharmaceutical research in the last decades. Hyaluronic acid a carbohydrate and mucopolysaccharide was chemically modified in order to achieve and establish a promising platform for buccal drug delivery. Aim: Novel biomaterial was tested for its potential for buccal drug delivery. Background: Polysaccharide hyaluronic acid (HA) was chemically modified with cysteine ethyl ether (CYS). By immobilization of the thiol-bearing ligand on the polymeric backbone the thiolated bioconjugate HA-CYS was obtained. Methodology: Mucoadhesive, permeation enhancing and stability potential as well as mechanical, physicochemical properties further mucoadhesive strength, swelling index and residence time were investigated. The developed thiolated bioconjugate displayed enhanced mucoadhesiveness on buccal mucosa as well as permeation behavior and polymer stability. The near neutral pH and negative cytotoxicity studies indicated their non-irritability and biocompatible nature with biological tissues. Further, the model drug sulforhodamine 101 was incorporated to determine its drug release profiles. Results: The synthesized thiomer showed no toxicity. The mucoadhesion of thiolated hyaluronic acid on buccal mucosa was significantly improved in comparison to unmodified one. The biomaterial showed 2.5-fold higher stability in polymer structure. The release of sulforhodamine in the presence of thiolated hyaluronic acid was 2.3-fold increased compared to hyaluronic acid. Conclusion: Thus, the promising results encourage further investigations and exploitation of this versatile polysaccharide. So far, hyaluronic acid was not evaluated for buccal drug delivery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buccal%20delivery"
