Classical alkali-activated cements could be made more eco-efficient if the use of sodium silicate is avoided. Besides, most alkali-activated cements suffer from severe efflorescence originated by the fact that alkaline and/or soluble silicates that are added during processing cannot be totally consumed. This paper presents experimental results on hybrid alkaline cements. Compressive strength results and efflorescence’s observations show that the new mixes already analyzed are promising. SEM results show that no traditional porous ITZ was detected in these binders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20alkaline%20cements" title="hybrid alkaline cements">hybrid alkaline cements</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=efflorescence" title=" efflorescence"> efflorescence</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=ITZ" title=" ITZ"> ITZ</a> </p> <a href="https://publications.waset.org/abstracts/5468/compressive-strength-and-microstructure-of-hybrid-alkaline-cements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5468.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">293</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">399</span> A Furaneol-Containing Glass-Ionomer Cement for Enhanced Antibacterial Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dong%20Xie">Dong Xie</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuling%20Xu"> Yuling Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Leah%20Howard"> Leah Howard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Secondary caries is found to be one of the main reasons to the restoration failure of dental restoratives. To prevent secondary caries formation, dental restoratives ought to be made antibacterial. In this study, a natural fruit component furaneol was tethered onto polyacid, the formed polyacid was used to formulate the light-curable glass-ionomer cements, and then the effect of this new antibacterial compound on compressive strength (CS) and antibacterial activity of the formed cement was evaluated. Fuji II LC glass powders were used as fillers. Compressive strength (CS) and S. mutans viability were used to evaluate the mechanical strength and antibacterial activity of the formed cement. The experimental cement showed a significant antibacterial activity, accompanying with an initial CS reduction. Increasing the compound loading significantly decreased the S. mutans viability from 5 to 81% and also reduced the initial CS of the formed cements from 4 to 58%. The cement loading with 7% antibacterial polymer showed 168 MPa, 7.8 GPa, 243 MPa, 46 MPa, and 57 MPa in yield strength, modulus, CS, diametral tensile strength and flexural strength, respectively, as compared to 141, 6.9, 236, 42 and 53 for Fuji II LC. The cement also showed an antibacterial function to other bacteria. No human saliva effect was noticed. It is concluded that the experimental cement may potentially be developed to a permanent antibacterial cement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title="antibacterial">antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20materials" title=" dental materials"> dental materials</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20viability" title=" cell viability"> cell viability</a> </p> <a href="https://publications.waset.org/abstracts/67061/a-furaneol-containing-glass-ionomer-cement-for-enhanced-antibacterial-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67061.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">317</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">398</span> Influence of Preheating Self-Adhesive Cements on the Degree of Conversion, Cell Migration and Cell Viability in NIH/3T3</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Celso%20Afonso%20Klein%20Jr.">Celso Afonso Klein Jr.</a>, <a href="https://publications.waset.org/abstracts/search?q=Henrique%20Cantarelli"> Henrique Cantarelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Portella"> Fernando Portella</a>, <a href="https://publications.waset.org/abstracts/search?q=Keiichi%20Hosaka"> Keiichi Hosaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Reston"> Eduardo Reston</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabricio%20Collares"> Fabricio Collares</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Zimmer"> Roberto Zimmer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> TTo evaluate the influence of preheating self-adhesive cement at 39ºC on cell migration, cytotoxicity and degree of conversion. RelyX U200, Set PP and MaxCem Elite were subjected to a degree of conversion analysis (FTIR-ATR). For the cytotoxicity analysis, extracts (24 h and 7 days) were placed in contact with NIH/3T3 cells. For cell migration, images were captured of each sample until the possible closure of the cleft occurred. In the results of the degree of conversion, preheating did not improve the conversion of cement. For the MTT, preheating did not improve the results within 24 hours. However, it generated positive results within 7 days for the Set PP resin cement. For cell migration, high rates of cell death were found in all groups. It is concluded that preheating at 39ºC caused a positive effect only in increasing the cell viability of the Set PP resin cement and that both materials analyzed are highly cytotoxic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20cements" title="dental cements">dental cements</a>, <a href="https://publications.waset.org/abstracts/search?q=resin%20cements" title=" resin cements"> resin cements</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20of%20conversion" title=" degree of conversion"> degree of conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxicity" title=" cytotoxicity"> cytotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20migration%20assays" title=" cell migration assays"> cell migration assays</a> </p> <a href="https://publications.waset.org/abstracts/179105/influence-of-preheating-self-adhesive-cements-on-the-degree-of-conversion-cell-migration-and-cell-viability-in-nih3t3" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179105.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">72</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">397</span> Preparation and Characterization of Calcium Phosphate Cement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Thepsuwan">W.

In this study, CPCs were produced by using mixtures of tetracalcium phosphate (TTCP, Ca4O(PO4)2) and dicalcium phosphate anhydrous (DCPA, CaHPO4) in equimolar ratio (1/1) with aqueous solutions of acetic acid (C2H4O2) and disodium hydrogen phosphate dehydrate (Na2HPO4.2H2O) in combination with sodium alginate in order to improve theirs moldable characteristic. The concentrations of the aqueous solutions and sodium alginate were varied to investigate the effects of different aqueous solution and alginate on properties of the cements. The cement paste was prepared by mixing cement powder (P) with aqueous solution (L) in a P/L ratio of 1.0 g/ 0.35 ml. X-ray diffraction (XRD) was used to analyses phase formation of the cements. Setting times and compressive strength of the set CPCs were measured using the Gilmore apparatus and Universal testing machine, respectively. The results showed that CPCs could be produced by using both basic (Na2HPO4.2H2O) and acidic (C2H4O2) solutions. XRD results show the precipitation of hydroxyapatite in all cement samples. No change in phase formation among cements using difference concentrations of Na2HPO4.2H2O solutions. With increasing concentration of acidic solutions, samples obtained less hydroxyapatite with a high dicalcium phosphate dehydrate leaded to a shorter setting time. Samples with sodium alginate exhibited higher crystallization of hydroxyapatite than that of without alginate as a result of shorten setting time in basic solution but a longer setting time in acidic solution. The stronger cement was attained from samples using acidic solution with sodium alginate; however it was lower than using the basic solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcium%20phosphate%20cements" title="calcium phosphate cements">calcium phosphate cements</a>, <a href="https://publications.waset.org/abstracts/search?q=TTCP" title=" TTCP"> TTCP</a>, <a href="https://publications.waset.org/abstracts/search?q=DCPA" title=" DCPA"> DCPA</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroxyapatite" title=" hydroxyapatite"> hydroxyapatite</a>, <a href="https://publications.waset.org/abstracts/search?q=properties" title=" properties"> properties</a> </p> <a href="https://publications.waset.org/abstracts/17449/preparation-and-characterization-of-calcium-phosphate-cement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17449.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">390</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">396</span> Potential Use of Local Materials as Synthesizing One Part Geopolymer Cement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Areej%20Almalkawi">Areej Almalkawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sameer%20Hamadna"> Sameer Hamadna</a>, <a href="https://publications.waset.org/abstracts/search?q=Parviz%20Soroushian"> Parviz Soroushian</a>, <a href="https://publications.waset.org/abstracts/search?q=Nalin%20Darsana"> Nalin Darsana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work on indigenous binders in this paper focused on the following indigenous raw materials: red clay, red lava and pumice (as primary aluminosilicate precursors), wood ash and gypsum (as supplementary minerals), and sodium sulfate and lime (as alkali activators). The experimental methods used for evaluation of these indigenous raw materials included laser granulometry, x-ray fluorescence (XRF) spectroscopy, and chemical reactivity. Formulations were devised for transforming these raw materials into alkali aluminosilicate-based hydraulic cements. These formulations were processed into hydraulic cements via simple heating and milling actions to render thermal activation, mechanochemical and size reduction effects. The resulting hydraulic cements were subjected to laser granulometry, heat of hydration and reactivity tests. These cements were also used to prepare mortar mixtures, which were evaluated via performance of compressive strength tests. The measured values of strength were correlated with the reactivity, size distribution and microstructural features of raw materials. Some of the indigenous hydraulic cements produced in this reporting period yielded viable levels of compressive strength. The correlation trends established in this work are being evaluated for development of simple and thorough methods of qualifying indigenous raw materials for use in production of indigenous hydraulic cements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=one-part%20geopolymer%20cement" title="one-part geopolymer cement">one-part geopolymer cement</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminosilicate%20precursors" title=" aluminosilicate precursors"> aluminosilicate precursors</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20activation" title=" thermal activation"> thermal activation</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanochemical" title=" mechanochemical"> mechanochemical</a> </p> <a href="https://publications.waset.org/abstracts/65941/potential-use-of-local-materials-as-synthesizing-one-part-geopolymer-cement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65941.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">314</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">395</span> Sol-Gel Derived Yttria-Stabilized Zirconia Nanoparticles for Dental Applications: Synthesis and Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anastasia%20Beketova">Anastasia Beketova</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanouil-George%20C.%20Tzanakakis"> Emmanouil-George C.

Using sol-gel based synthesis as simple and cost-effective method, nano-sized YSZ particles with high purity can be produced. The aim of this study was to synthesize YSZ nanoparticles by the Pechini sol-gel method at different temperatures and to investigate their composition, structure, and morphology. YSZ nanopowders were synthesized by the sol-gel method using zirconium oxychloride octahydrate (ZrOCl₂.8H₂O) and yttrium nitrate hexahydrate (Y(NO₃)₃.6H₂O) as precursors with the addition of acid chelating agents to control hydrolysis and gelation reactions. The obtained powders underwent TG_DTA analysis and were sintered at three different temperatures: 800, 1000, and 1200°C for 2 hours. Their composition and morphology were investigated by Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction Analysis (XRD), Scanning Electron Microscopy with associated with Energy Dispersive X-ray analyzer (SEM-EDX), Transmission Electron Microscopy (TEM) methods, and Dynamic Light Scattering (DLS). FTIR and XRD analysis showed the presence of pure tetragonal phase in the composition of nanopowders. By increasing the calcination temperature, the crystallinity of materials increased, reaching 47.2 nm for the YSZ1200 specimens. SEM analysis at high magnifications and DLS analysis showed submicron-sized particles with good dispersion and low agglomeration, which increased in size as the sintering temperature was elevated. From the TEM images of the YSZ1000 specimen, it can be seen that zirconia nanoparticles are uniform in size and shape and attain an average particle size of about 50 nm. The electron diffraction patterns clearly revealed ring patterns of polycrystalline tetragonal zirconia phase. Pure YSZ nanopowders have been successfully synthesized by the sol-gel method at different temperatures. Their size is small, and uniform, allowing their incorporation of dental luting resin cements to improve their mechanical properties and possibly enhance the bond strength of demanding dental ceramics such as zirconia to the tooth structure.

The research allows comparing some different cements in order to the potential risk of water contamination. This can be done only in the same environment. To reach the results in reasonable short time intervals and to make heavy metals measurements with high accuracy, demineralized water was used. In this case the conditions of experiments are far away from the water supply practice, but short time experiments and measurably high concentrations of elements in the water solution are an important advantage. Moreover leaching mechanisms can be recognized, our experiments reported here refer to this kind of cements evaluation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20corrosion" title="concrete corrosion">concrete corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20sulfide" title=" hydrogen sulfide"> hydrogen sulfide</a>, <a href="https://publications.waset.org/abstracts/search?q=odors" title=" odors"> odors</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20sewers" title=" reinforced concrete sewers"> reinforced concrete sewers</a>, <a href="https://publications.waset.org/abstracts/search?q=sewerage" title=" sewerage"> sewerage</a> </p> <a href="https://publications.waset.org/abstracts/17708/cement-mortar-lining-as-a-potential-source-of-water-contamination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17708.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">208</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">392</span> Modification of Toothpaste Formula Using Pineapple Cobs and Eggshell Waste as a Way to Decrease Dental Caries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Achmad%20Buhori">Achmad Buhori</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Imam%20Pratama"> Reza Imam Pratama</a>, <a href="https://publications.waset.org/abstracts/search?q=Tissa%20Wiraatmaja"> Tissa Wiraatmaja</a>, <a href="https://publications.waset.org/abstracts/search?q=Wanti%20Megawati"> Wanti Megawati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data from many countries indicates that there is a marked increase of dental caries. The increases in caries appear to occur in lower socioeconomic groups. It is possible that the benefits of prevention of dental caries are not reaching these groups. However, there is a way to decrease dental caries by adding 5% of bromelain and calcium as an active agent in toothpaste. Bromelain can break glutamine-alanine bond and arginine-alanine bond which is a constituent of amino acid that causes dental plague which is one of the factors of dental caries. Calcium help rebuilds the teeth by strengthening and repairing enamel. Bromelain can be found from the extraction of pineapple (Ananas comosus) cobs (88.86-94.22 % of bromelain recovery during extraction based on the enzyme unit) and calcium can be taken from eggshell (95% of dry eggshell consist of calcium). The aim of this experiment is to make a toothpaste which contains bromelain and calcium as an effective, cheap, and healthy way to decrease dental caries around the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bromelain" title="bromelain">bromelain</a>, <a href="https://publications.waset.org/abstracts/search?q=calcium" title=" calcium"> calcium</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20caries" title=" dental caries"> dental caries</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20plague" title=" dental plague"> dental plague</a>, <a href="https://publications.waset.org/abstracts/search?q=toothpaste" title=" toothpaste"> toothpaste</a> </p> <a href="https://publications.waset.org/abstracts/54683/modification-of-toothpaste-formula-using-pineapple-cobs-and-eggshell-waste-as-a-way-to-decrease-dental-caries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54683.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">270</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">391</span> Resons for Seeking Dental Care, Caries Profile and Treatment Need of Children in Tabuk, KSA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Ameer%20Haider%20Jafri">Syed Ameer Haider Jafri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Amri"> Mariam Amri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dental caries is the most prevalent dental disease of childhood.

To efficiently use slag and limestone, it is necessary to carefully select the particle size distribution (PSD) of the binders. This study investigated the effects of the PSD of binders on the performance of slag-limestone ternary cement. The Portland cement (PC) was prepared by grinding 95% clinker + 5% gypsum. Based on the PSD parameters of the binders, three types of ternary cements with a similar overall PSD were designed, i.e., NO.1 fine slag, medium PC, and coarse limestone; NO.2 fine limestone, medium PC, and coarse slag; NO.3. fine PC, medium slag, and coarse limestone. The binder contents in the ternary cements were (a) 50 % PC, 40 % slag, and 10 % limestone (called high cement group) or (b) 35 % PC, 55 % slag, and 10 % limestone (called low cement group). The pure PC and binary cement with 50% slag and 50% PC prepared with the same binders as the ternary cement were considered as reference cements. All these cements were used to investigate the mortar performance in terms of workability, strength at 2, 7, 28, and 90 days, carbonation resistance, and non-steady state chloride migration resistance at 28 and 56 days. Results show that blending medium PC with fine slag could exhibit comparable performance to blending fine PC with medium/coarse slag in binary cement. For the three ternary cements in the high cement group, ternary cement with fine limestone (NO.2) shows the lowest strength, carbonation, and chloride migration performance. Ternary cements with fine slag (NO.1) and with fine PC (NO.3) show the highest flexural strength at early and late ages, respectively. In addition, compared with ternary cement with fine PC (NO.3), ternary cement with fine slag (NO.1) has a similar carbonation resistance and a better chloride migration resistance. For the low cement group, three ternary cements have a similar flexural and compressive strength before 7 days. After 28 days, ternary cement with fine limestone (NO.2) shows the highest flexural strength while fine PC (NO.3) has the highest compressive strength. In addition, ternary cement with fine slag (NO.1) shows a better chloride migration resistance but a lower carbonation resistance compared with the other two ternary cements. Moreover, the durability performance of ternary cement with fine PC (NO.3) is better than that of fine limestone (NO.2). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=limestone" title="limestone">limestone</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size%20distribution" title=" particle size distribution"> particle size distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=slag" title=" slag"> slag</a>, <a href="https://publications.waset.org/abstracts/search?q=ternary%20cement" title=" ternary cement"> ternary cement</a> </p> <a href="https://publications.waset.org/abstracts/152245/effects-of-particle-size-distribution-of-binders-on-the-performance-of-slag-limestone-ternary-cement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152245.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">126</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">389</span> Dental Appointments and Related Fear and Anxiety among the General Population during the COVID-19 Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paria%20Koraei">Paria Koraei</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Ahmadzadeh"> Meysam Ahmadzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Shahriarirad"> Reza Shahriarirad</a>, <a href="https://publications.waset.org/abstracts/search?q=Keivan%20Ranjbar"> Keivan Ranjbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzane%20Farahmand"> Farzane Farahmand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rapid spread of the coronavirus disease 2019 (COVID-19) has enlisted dental offices in high-risk places. A cross-sectional survey was carried out among the general population aged 17 and above in Shiraz, Fars, Iran. The patients' demographic features were recorded and analyzed against questions regarding fear, anxiety, and attitude toward dental appointments. The Dental Anxiety Scale (DAS) questionnaire was used for the evaluation of anxiety levels. Among a total of 760 participants, the average age was 32.33±11.27 years, while 242 (31.8%) were male and 357 (47%) were single. Based on the anxiety scores, 336 (44.2%) participants had mild anxiety, 215 (28.3%) had moderate anxiety, 74 (9.7%) had high, and 135 (17.8%) had severe anxiety. The majority of participants used masks (93.8%) and disinfectants (79.9%) during dental visits, and the most emphasized policies during dental visits were using disposable face masks by the personnel (83.6%) and controlling the number of visitors in the office (81.8%). Only 226 (29.7%) reported that they hadn’t postponed their dental visits. Our findings demonstrated that anxiety in people increases toward dental treatments during the COVID-19 pandemic, resulting in decreased dental appointments. Dentally anxious people were more likely to be female and married couples. Being female and older age are possible risk factors for developing a fear of dental procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title="Covid-19">Covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=fear" title=" fear"> fear</a>, <a href="https://publications.waset.org/abstracts/search?q=dentistry" title=" dentistry"> dentistry</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20care" title=" dental care"> dental care</a> </p> <a href="https://publications.waset.org/abstracts/175926/dental-appointments-and-related-fear-and-anxiety-among-the-general-population-during-the-covid-19-pandemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175926.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">92</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">388</span> Design Improvement of Dental Implant-Based on Bone Remodelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Solehuddin%20Shuib">Solehuddin Shuib</a>, <a href="https://publications.waset.org/abstracts/search?q=Koay%20Boon%20Aik"> Koay Boon Aik</a>, <a href="https://publications.waset.org/abstracts/search?q=Zainul%20Ahmad%20Rajion"> Zainul Ahmad Rajion</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are many types of mechanical failure on the dental implant. In this project, the failure that needs to take into consideration is the bone resorption on the dental implant. Human bone has its ability to remodel after the implantation. As the dental implant is installed into the bone, the bone will detect and change the bone structure to achieve new biomechanical environment. This phenomenon is known as bone remodeling. The objective of the project is to improve the performance of dental implant by using different types of design. These designs are used to analyze and predict the failure of the dental implant by using finite element analysis (FEA) namely ANSYS. The bone is assumed to be fully attached to the implant or cement. Hence, results are then compared with other researchers. The results were presented in the form of Von Mises stress, normal stress, shear stress analysis, and displacement. The selected design will be analyzed further based on a theoretical calculation of bone remodeling on the dental implant. The results have shown that the design constructed passed the failure analysis. Therefore, the selected design is proven to have a stable performance at the recovery stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20implant" title="dental implant">dental implant</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA"> FEA</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20remodeling" title=" bone remodeling"> bone remodeling</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a> </p> <a href="https://publications.waset.org/abstracts/19662/design-improvement-of-dental-implant-based-on-bone-remodelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19662.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">501</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">387</span> Analysis of in Vitro Biocompatibility Studies of Silicate-Based Bioceramic Cements: A Scoping Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olphiara%20Rodolpheza%20Alexandre">Olphiara Rodolpheza Alexandre</a>, <a href="https://publications.waset.org/abstracts/search?q=Carla%20David"> Carla David</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Guerra%20Lund"> Rafael Guerra Lund</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Ferreira"> Nadia Ferreira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the increasing demand for biomaterials in the dental field, especially in endodontics, calcium silicate-based cements (CSCs) have gained prominence because of their biocompatibility and tissue regeneration capabilities. Originating from Mineral Trioxide Aggregate (MTA), the first bioceramic in endodontics derived from Portland cement, these materials are becoming increasingly prevalent in the market. For any drug released to the market, pharmacovigilance must ensure the absence of adverse health effects on consumers through rigorous toxicological testing. Although these materials have undergone in vitro and in vivo testing, such tests have typically been conducted over a limited period. Some effects may only become apparent after several years, and these studies are generally carried out on a non-specific population. However, the variety of calcium silicate-based products, including cement and sealers, raises questions about their toxicity, particularly considering potential long-term effects not addressed in existing studies. While the scientific literature includes comparative studies on the toxicity of these materials, the consistency of their conclusions is often controversial. Therefore, this project aims to map the scientific evidence from in vitro biocompatibility studies, including those investigating the toxicity of calcium silicate-based bioceramics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=toxicity" title="toxicity">toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity%20test" title=" toxicity test"> toxicity test</a>, <a href="https://publications.waset.org/abstracts/search?q=bioceramics" title=" bioceramics"> bioceramics</a>, <a href="https://publications.waset.org/abstracts/search?q=calcium%20silicate" title=" calcium silicate"> calcium silicate</a>, <a href="https://publications.waset.org/abstracts/search?q=genotoxicity" title=" genotoxicity"> genotoxicity</a> </p> <a href="https://publications.waset.org/abstracts/189472/analysis-of-in-vitro-biocompatibility-studies-of-silicate-based-bioceramic-cements-a-scoping-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189472.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">30</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">386</span> Fear and Anxiety among School Age Children Undergoing Dental Treatment in an Oral Health Unit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Ibrahim%20Mohamed%20Khalifa">Maha Ibrahim Mohamed Khalifa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Dental fear and anxiety lead to avoidance of dental treatment and deterioration of oral health.

The clays materials react with alkaline solution (10, 14 and 18 mol(NaOH)/L) in order to produce geopolymer cements whose pastes were characterized by determining their water adsorption and compressive strength. The compressive strength of the hardened geopolymer cement paste samples aged 28 days attained its highest value (32.3MPa) around 950°C for NaOH concentration of 14M. The water adsorption value of the prepared samples decreased with increasing the calcination temperature of clay fractions. It can be concluded that the most suitable temperature for the calcination of illitio-kaolinitic clays in view of producing geopolymer cements is around 950°C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title="compressive strength">compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=geopolymer%20cement" title=" geopolymer cement"> geopolymer cement</a>, <a href="https://publications.waset.org/abstracts/search?q=illitio-kaolinitic%20clay" title=" illitio-kaolinitic clay"> illitio-kaolinitic clay</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral" title=" mineral"> mineral</a> </p> <a href="https://publications.waset.org/abstracts/17201/preparation-of-geopolymer-cements-from-tunisian-illito-kaolinitic-clay-mineral" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17201.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">252</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">384</span> Dental Ethics versus Malpractice, as Phenomenon with a Growing Trend</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saimir%20Heta">Saimir Heta</a>, <a href="https://publications.waset.org/abstracts/search?q=Kers%20Kapaj"> Kers Kapaj</a>, <a href="https://publications.waset.org/abstracts/search?q=Rialda%20Xhizdari"> Rialda Xhizdari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilma%20Robo"> Ilma Robo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dealing with emerging cases of dental malpractice with justifications that stem from the clear rules of dental ethics is a phenomenon with an increasing trend in today's dental practice. Dentists should clearly understand how far the limit of malpractice goes, with or without minimal or major consequences, for the affected patient, which can be justified as a complication of dental treatment, in support of the rules of dental ethics in the dental office. Indeed, malpractice can occur in cases of lack of professionalism, but it can also come as a consequence of anatomical and physiological limitations in the implementation of the dental protocols, predetermined and indicated by the patient in the paragraph of the treatment plan in his personal card. This study is of the review type with the aim of the latest findings published in the literature about the problem of dealing with these phenomena. The combination of keywords is done in such a way with the aim to give the necessary space for collecting the right information in the networks of publications about this field, always first from the point of view of the dentist and not from that of the lawyer or jurist. From the findings included in this article, it was noticed the diversity of approaches towards the phenomenon depends on the different countries based on the legal basis that these countries have. There is a lack of or a small number of articles that touch on this topic, and these articles are presented with a limited number of data on the same topic. Conclusions: Dental malpractice should not be hidden under the guise of various dental complications that we justify with the strict rules of ethics for patients treated in the dental chair. The individual experience of dental malpractice must be published with the aim of serving as a source of experience for future generations of dentists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20ethics" title="dental ethics">dental ethics</a>, <a href="https://publications.waset.org/abstracts/search?q=malpractice" title=" malpractice"> malpractice</a>, <a href="https://publications.waset.org/abstracts/search?q=professional%20protocol" title=" professional protocol"> professional protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20deviation" title=" random deviation"> random deviation</a> </p> <a href="https://publications.waset.org/abstracts/164017/dental-ethics-versus-malpractice-as-phenomenon-with-a-growing-trend" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164017.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">96</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">383</span> Environmental and Health Risks Associated with Dental Waste Management: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Y.%20Babanyara">Y.

The waste generated in the dental clinics has the potential for spreading infections and causing diseases, so improper disposal of these dental wastes can cause harm to the dentist, the people in immediate vicinity of the dentist, waste handlers, general public and the environment through production of toxins or as by-products of the destruction process. Staff that provide dental healthcare ought to be aware of the proper handling and the system of management of dental waste used by different dental hospitals. The method of investigation adopted in the paper involved a desk study in which documents and records relating to dental waste handling were studied to obtain background information on existing dental waste management in Nigeria other countries of the world are also mentioned as examples. Additionally, information on generation, handling, segregation, risk associated during handling and treatment of dental medical waste were sought in order to determine the best method for safe disposal. This article provides dentists with the information they need to properly dispose of mercury and amalgam waste, and provides suggestions for managing the other wastes that result from the day-to-day activities of a dental office such as: used X-ray fixers and developers; cleaners for X-ray developer systems; lead foils, shields and aprons; chemiclave/chemical sterilant solutions; disinfectants, cleaners, and other chemicals; and, general office waste. Additionally, this study may be beneficial for authorities and researchers of developing countries to work towards improving their present dental waste management system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clinic" title="clinic">clinic</a>, <a href="https://publications.waset.org/abstracts/search?q=dental" title=" dental"> dental</a>, <a href="https://publications.waset.org/abstracts/search?q=disposal" title=" disposal"> disposal</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a> </p> <a href="https://publications.waset.org/abstracts/35356/environmental-and-health-risks-associated-with-dental-waste-management-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35356.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">318</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">382</span> Evaluating Psychosocial Influence of Dental Aesthetics: A Cross-Sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahjabeen%20Akbar">Mahjabeen Akbar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dental aesthetics and its associated psychosocial influence have a significant impact on individuals. Correcting malocclusions is a key motivating factor for majority patients; however, psychosocial factors have been rarely incorporated in evaluating malocclusions. Therefore, it is necessary to study the psychosocial influence of malocclusion in patients. The study aimed to determine the psychosocial influence of dental aesthetics in dental students by the ‘Psychosocial Impact of Dental Aesthetics Questionnaire’ and self-rated Aesthetic Component of the Index of Orthodontic Treatment Need (IOTN). This was a quantitative study using a cross-sectional study design. One hundred twenty dental students (71 females and 49 males; mean age 24.5) were selected via purposive sampling from July to August 2019. Dental students with no former orthodontic treatment were requested to fill out the ‘Psychosocial Impact of Dental Aesthetics Questionnaire.’ Variables including; self-confidence/insecurity, social influence, psychological influence and self-perception of the need of an orthodontic treatment were evaluated by a sequence of statements, while dental aesthetics were evaluated by using the IOTN Aesthetic Component. To determine the significance, the Kruskal-Wallis test was utilized. The results show that all four variables measuring psychosocial impact indicated significant correlations with the perceived malocclusions with a p-value of less than 0.01. The results conclude there is a strong psychological and social influence of altered dental aesthetics on an individual. Moreover, the relationship between the IOTN-AC grading with the psychosocial wellbeing of an individual stands proven, indicating that the perception of altered dental aesthetics is as important as a factor in treatment need as the amount of malocclusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20aesthetics" title="dental aesthetics">dental aesthetics</a>, <a href="https://publications.waset.org/abstracts/search?q=malocclusion" title=" malocclusion"> malocclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=psychosocial%20influence" title=" psychosocial influence"> psychosocial influence</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20students" title=" dental students"> dental students</a> </p> <a href="https://publications.waset.org/abstracts/119136/evaluating-psychosocial-influence-of-dental-aesthetics-a-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119136.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">151</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">381</span> From Patient Satisfaction to Dental Service Reutilization: Innovative Solutions for Improving Dental Care Services</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Kian%20Haji%20Seyed%20Javadi">Seyed Kian Haji Seyed Javadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aisan%20Nouri"> Aisan Nouri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Patient satisfaction in dental care is shaped by experiences throughout the treatment journey. Challenges such as fear, lack of trust and poor communication can impact patient contentment and willingness to seek dental care. This narrative review explores these issues and presents innovative solutions to address them by searching PubMed and Scopus data sources. It examines factors affecting patient satisfaction and adherence across three phases—before, during and after treatment—emphasizing the roles of effective communication, payment and follow-up systems, appointment scheduling, welcoming reception and the treatment environment. The factors discussed in this study motivate patients to return for routine check-ups and preventive care, even if their initial visit was for an emergency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=patient%20satisfaction" title="patient satisfaction">patient satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=dentistry" title=" dentistry"> dentistry</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20access" title=" dental access"> dental access</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20care%20services" title=" dental care services"> dental care services</a> </p> <a href="https://publications.waset.org/abstracts/192683/from-patient-satisfaction-to-dental-service-reutilization-innovative-solutions-for-improving-dental-care-services" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192683.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">19</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">380</span> Relation between Initial Stability of the Dental Implant and Bone-Implant Contact Level</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jui-Ting%20Hsu">Jui-Ting Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Heng-Li%20Huang"> Heng-Li Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming-Tzu%20Tsai"> Ming-Tzu Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuo-Chih%20Su"> Kuo-Chih Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Lih-Jyh%20Fuh"> Lih-Jyh Fuh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objectives of this study were to measure the initial stability of the dental implant (ISQ and PTV) in the artificial foam bone block with three different quality levels.

However, sometimes complications arise, which lead to the loss of the implant as well as the prosthesis. Fracture of dental implants is rare; however, at times, implants or abutment screws fracture and lead to many problems for the clinician and the patient. Possible causes of implant fracture include improper design, overload, fatigue and corrosion. Six retrieved fractured dental implants, with varying diameters and designs, were collected from time to time to examine by scanning electron microscope (SEM) to characterize fracture behavior and assess the mechanism of fracture. In this investigation, it was observed that fracture of the five dental implants occurred due to fatigue crack initiation and propagation from the thread roots. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium" title="titanium">titanium</a>, <a href="https://publications.waset.org/abstracts/search?q=dental" title=" dental"> dental</a>, <a href="https://publications.waset.org/abstracts/search?q=implant" title=" implant"> implant</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a> </p> <a href="https://publications.waset.org/abstracts/171204/failure-analysis-of-fractured-dental-implants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171204.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">81</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">378</span> Side Effects of Dental Whitening: Published Data from the Literature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ilma%20Robo">Ilma Robo</a>, <a href="https://publications.waset.org/abstracts/search?q=Saimir%20Heta"> Saimir Heta</a>, <a href="https://publications.waset.org/abstracts/search?q=Emela%20Dalloshi"> Emela Dalloshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nevila%20Alliu"> Nevila Alliu</a>, <a href="https://publications.waset.org/abstracts/search?q=Vera%20Ostreni"> Vera Ostreni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The dental whitening process, beyond the fact that it is a mini-invasive dental treatment, has effects on the dental structure, or on the pulp of the tooth, where it is applied. The electronic search was performed using keywords to find articles published within the last 10 years about side effects, assessed as such, of minimally invasive dental bleaching treatment. Methodology: In selected articles, the other aim of the study was to evaluate the side effects of bleaching based on the percentage and type of solution used, where the latter was evaluated on the basic solution used for bleaching. Results: The side effects of bleaching are evaluated in selected articles depending on the method of bleaching application, which means it is carried out with recommended solutions, or with mixtures of alternative solutions or substances based on Internet information. Short conclusion: The dental bleaching process has side effects which have not yet been definitively evaluated, experimentally in large samples of individuals or animals (mice or cattle) to arrive at accurate numerical conclusions. The trend of publications about this topic is increasing in recent years, as long as the trend for aesthetic facial treatments, including dental ones, is increasing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teeth%20whitening" title="teeth whitening">teeth whitening</a>, <a href="https://publications.waset.org/abstracts/search?q=side%20effects" title=" side effects"> side effects</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20teeth" title=" permanent teeth"> permanent teeth</a>, <a href="https://publications.waset.org/abstracts/search?q=formed%20dental%20apex" title=" formed dental apex"> formed dental apex</a> </p> <a href="https://publications.waset.org/abstracts/182709/side-effects-of-dental-whitening-published-data-from-the-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182709.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">63</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">377</span> Dental Management Particularities of Werner Syndrome: A Report of Two Cases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emna%20Abid">Emna Abid</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Chebbi"> Linda Chebbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yosra%20Mabrouk"> Yosra Mabrouk</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Labidi"> Amel Labidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Mansour"> Lamia Mansour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Werner syndrome (WS) is a rare genetic disorder inherited in an autosomal recessive pattern characterized by accelerated aging. While extensive research has been conducted on its systemic manifestations, the specific dental implications of WS remain poorly understood. The medical history and the oral health status of two patients diagnosed with WS were detailed. Our findings revealed a high prevalence of dental problems in both patients, including periodontitis, xerostomia, and temporomandibular joint disorders. This article aims to investigate the dental challenges faced by individuals with WS as well as the prosthetic options envisaged through two clinical cases contributing to a deeper understanding of the dental implications of WS and to choose the appropriate prosthetic solution in this population.

The results would highlight the importance of conducting awareness campaigns in the community to promote good oral healthcare in Kuwait. Materials and Methods: A cross-sectional descriptive survey was carried out among dental patients attending KUDC. A structured questionnaire, in both Arabic and English languages, was used for data collection about the socio-demographic characteristics, knowledge about the dental cross-infection, and attitudes and self-reported practices regarding infection transmission and control in dentistry. Results: A response rate of 80% (202/250) was reported. 47% of respondents had poor knowledge about dental infection transmission, and only 19.8% had satisfactory knowledge. Female participants obtained a higher satisfactory score (14.3%) compared to males (5.5%). Patients with a university degree or higher education had a better level of knowledge compared to patients with a lower educational level (p < 0.05). The majority of participants agreed that the dentist should wear gloves (95.5%), masks (89.6%), safety glasses (70.3%), and gowns (84.7%). Many patients believed that the protection measures are mainly to stop the infection transmission from patient to patient via the dentist. Half of the participants would ask if the instruments are sterilized and might accept treatment from non-vaccinated dentists. Conclusions: Many dental patients attending KUDC have obtained poor knowledge scores regarding infection transmission in the dental clinic. The educational level was significantly associated with their level of knowledge. An overall positive attitude was reported regarding the infection control protocols practiced in the dental clinic. Raising awareness among dental patients about dental infection transmission and protective measures is of utmost importance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20infection" title="dental infection">dental infection</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20patients" title=" dental patients"> dental patients</a>, <a href="https://publications.waset.org/abstracts/search?q=infection%20control" title=" infection control"> infection control</a> </p> <a href="https://publications.waset.org/abstracts/110451/attitudes-and-knowledge-of-dental-patients-towards-infection-control-measures-in-kuwait-university-dental-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110451.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">137</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">375</span> Petrologic and Geochemical Characteristics of Marine Sand Strip in the Proterozoic Chuanlinggou Formation of the North China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yue%20Feng">Yue Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-jiang%20Wang"> Chun-jiang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhi-long%20Huang"> Zhi-long Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of the sedimentary environment of Mesoproterozoic marine deposits in North China has attracted special attention in recent years. It is not clear that the sedimentary environment and the cause of formation of the sandstone strip and its internal carbonate cements and pyrite in the Mesoproterozoic Chuanlinggou Formation in North China. In this study, drilling core samples in North China were identified by microscopy, and their petrological characteristics such as mineral composition and structure were identified. The geochemical data of carbon and oxygen isotopes, total organic carbon (TOC) contents and total sulfur (TS) contents were obtained by processing and analyzing the samples. The samples are mainly quartz particles with low compositional maturity, combined with low value of TOC, it shows that the sedimentary environment of the sandy clastic is a sandy littoral sedimentary environment with relative strong hydrodynamic force, and then the sandstone strip in black shale are formed by the deposition of gravity flow. Analysis of TS values reflect sandstone bands formed in hypoxic environments. The carbonate cements and the pyrite in the sandstone belt are authigenic. The carbon isotope values of authigenic carbonate cements are negatively biased in comparison with the carbonate isotope of carbonate rocks in the same period, but it is more biased than the carbon isotopic values of anaerobic oxidation of methane (AOM) genetic carbonate rocks. Authigenic pyrite may be mainly due to the formation of HS- by the action of bacterial sulfate reduction (BSR) and Fe²⁺, their causes are in contact. This indicates that authigenic carbonate cements are mainly carbonate precipitates formed but are significantly affected by the effects of AOM. Summary, the sedimentary environment of the sandstone zone in the Chuanlinggou Formation in the North China is a shallow sea facies with iron rich and anoxic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sandstone%20strip" title="sandstone strip">sandstone strip</a>, <a href="https://publications.waset.org/abstracts/search?q=sedimentary%20environment" title=" sedimentary environment"> sedimentary environment</a>, <a href="https://publications.waset.org/abstracts/search?q=authigenic%20carbonate%20cements" title=" authigenic carbonate cements"> authigenic carbonate cements</a>, <a href="https://publications.waset.org/abstracts/search?q=authigenic%20pyrite" title=" authigenic pyrite"> authigenic pyrite</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Chuanlinggou%20group" title=" The Chuanlinggou group"> The Chuanlinggou group</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20China" title=" North China"> North China</a> </p> <a href="https://publications.waset.org/abstracts/95234/petrologic-and-geochemical-characteristics-of-marine-sand-strip-in-the-proterozoic-chuanlinggou-formation-of-the-north-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95234.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">374</span> Quality Control of Distinct Cements by IR Spectroscopy: First, insights into Perspectives and Opportunities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Bader">Tobias Bader</a>, <a href="https://publications.waset.org/abstracts/search?q=Joerg%20Rickert"> Joerg Rickert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One key factor in achieving net zero emissions along the cement and concrete value chain in Europe by 2050 is the use of distinct constituents to produce improved and advanced cements. These cements will contain e.g. calcined clays, recycled concrete fines that are chemically similar as well as X-ray amorphous and therefore difficult to distinguish. This leads to enhanced requirements on the analytical methods for quality control regarding accuracy as well as reproducibility due to the more complex cement composition. With the methods currently provided for in the European standards, it will be a challenge to ensure reliable analyses of the composition of the cements. In an ongoing research project, infrared (IR) spectroscopy in combination with mathematical tools (chemometrics) is going to be evaluated as an additional analytical method with fast and low preparation effort for the characterization of silicate-based cement constituents. The resulting comprehensive database should facilitate determination of the composition of new cements. First results confirmed the applicability of near-infrared IR for the characterization of traditional silicate-based cement constituents (e.g. clinker, granulated blast furnace slag) and modern X-ray amorphous constituents (e.g. calcined clay, recycled concrete fines) as well as different sulfate species (e.g. gypsum, hemihydrate, anhydrite). A multivariant calibration model based on numerous calibration mixtures is in preparation. The final analytical concept to be developed will form the basis for establishing IR spectroscopy as a rapid analytical method for characterizing material flows of known and unknown inorganic substances according to their material properties online and offline. The underlying project was funded by the Federal Institute for Research on Building, Urban Affairs and Spatial Development on behalf of the Federal Ministry of Housing, Urban Development and Building with funds from the ‘Zukunft Bau’ research programme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cement" title="cement">cement</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20spectroscopy" title=" infrared spectroscopy"> infrared spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20control" title=" quality control"> quality control</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20amorphous" title=" X-ray amorphous"> X-ray amorphous</a> </p> <a href="https://publications.waset.org/abstracts/188878/quality-control-of-distinct-cements-by-ir-spectroscopy-first-insights-into-perspectives-and-opportunities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188878.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">39</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">373</span> Dental Pathologies and Agriculture: Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Andr%C3%A9s%20M%C3%A1rquez%20Ortiz">Ricardo Andrés Márquez Ortiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The objective of this literature review is to compile updated information from studies that have addressed the association between dental pathologies and agriculture. Materials and method: The research carried out corresponds to a documentary study of ex post facto retrospective, historiographic, and bibliometric design. An exhaustive bibliographic review search was carried out in databases and the Internet, books and articles on dental anthropology, archeology, and dentistry, on the relationship between dental pathologies and agriculture in prehistoric and current populations from different parts of the world. Subsequently, data collection was carried out through the ATLAS.ti computer program. Conclusions: In an influential article by Turner, which addresses the correlation between caries and the way of subsistence of both prehistoric and modern populations (hunting and gathering, mixed and agricultural economies), an average of 1.3% was found in hunter-gatherer societies, and 10.4% in agricultural societies. Sreebny compared global grain supply data (rice, wheat and corn) with DMF (spoiled, lost and blocked) rates. He concluded that rice has no association with dental caries, corn has a negative correlation, and wheat has a positive correlation. Additionally, intensive monoculture agricultural production systems cause an increase in dental pathologies. Meanwhile, polyculture agriculture, which leads to a more varied diet, generates a better state of dental health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20pathologies" title="dental pathologies">dental pathologies</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20production%20systems" title=" agricultural production systems"> agricultural production systems</a>, <a href="https://publications.waset.org/abstracts/search?q=extensive%20agriculture" title=" extensive agriculture"> extensive agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20anthropology" title=" dental anthropology"> dental anthropology</a> </p> <a href="https://publications.waset.org/abstracts/185767/dental-pathologies-and-agriculture-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185767.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">44</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">372</span> Age Estimation Using Destructive and Non-Destructive Dental Methods on an Archeological Human Sample from the Poor Claire Nunnery in Brussels, Belgium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pilar%20Cornejo%20Ulloa">Pilar Cornejo Ulloa</a>, <a href="https://publications.waset.org/abstracts/search?q=Guy%20Willems"> Guy Willems</a>, <a href="https://publications.waset.org/abstracts/search?q=Steffen%20Fieuws"> Steffen Fieuws</a>, <a href="https://publications.waset.org/abstracts/search?q=Kim%20Quintelier"> Kim Quintelier</a>, <a href="https://publications.waset.org/abstracts/search?q=Wim%20Van%20Neer"> Wim Van Neer</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Thevissen"> Patrick Thevissen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dental age estimation can be performed both in living and deceased individuals. In anthropology, few studies have tested the reliability of dental age estimation methods complementary to the usually applied osteological methods. Objectives: In this study, destructive and non-destructive dental age estimation methods were applied on an archeological sample in order to compare them with the previously obtained anthropological age estimates. Materials and Methods: One hundred and thirty-four teeth from 24 individuals were analyzed using Kvaal, Kvaal and Solheim, Bang and Ramm, Lamendin, Gustafson, Maples, Dalitz and Johanson’s methods. Results: A high variability and wider age ranges than the ones previously obtained by the anthropologist could be observed. Destructive methods had a slightly higher agreement than the non-destructive. Discussion: Due to the heterogeneity of the sample and the lack of the real age at death, the obtained results were not representative, and it was not possible to suggest one dental age estimation method over another. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=archeology" title="archeology">archeology</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20age%20estimation" title=" dental age estimation"> dental age estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic%20anthropology" title=" forensic anthropology"> forensic anthropology</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic%20dentistry" title=" forensic dentistry"> forensic dentistry</a> </p> <a href="https://publications.waset.org/abstracts/68933/age-estimation-using-destructive-and-non-destructive-dental-methods-on-an-archeological-human-sample-from-the-poor-claire-nunnery-in-brussels-belgium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68933.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">371</span> Dental Pathologies and Diet in Pre-hispanic Populations of the Equatorial Pacific Coast: Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Andr%C3%A9s%20M%C3%A1rquez%20Ortiz">Ricardo Andrés Márquez Ortiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective. The objective of this literature review is to compile updated information from studies that have addressed the association between dental pathologies and diet in prehistoric populations of the equatorial Pacific coast. Materials and method. The research carried out corresponds to a documentary study of ex post facto retrospective, historiographic and bibliometric design. A bibliographic review search was carried out in the libraries of the Colombian Institute of Anthropology and History (ICANH) and the National University of Colombia for books and articles on the archeology of the region. In addition, a search was carried out in databases and the Internet for books and articles on dental anthropology, archeology and dentistry on the relationship between dental pathologies and diet in prehistoric and current populations from different parts of the world. Conclusions. The complex societies (500 BC - 300 AD) of the equatorial Pacific coast used an agricultural system of intensive monoculture of corn (Zea mays). This form of subsistence was reflected in an intensification of dental pathologies such as dental caries, dental abscesses generated by cavities, and enamel hypoplasia associated with a lower frequency of wear. The Upper Formative period (800 A.D. -16th century A.D.) is characterized by the development of polyculture, slash-and-burn agriculture, as an adaptive agricultural strategy to the ecological damage generated by the intensive economic activity of complex societies. This process leads to a more varied diet, which generates better dental health. <p class="card-text"><strong>Keywords:</strong> <a
