Use Of Artificial Teeth Research Articles

A comparative evaluation of student experience with artificial teeth used in pre-clinical fixed prosthodontics post-core undergraduate teaching programs.

Research is lacking in the use of artificial teeth for post-core techniques in undergraduate fixed prosthodontics pre-clinical education. The aim of this study was to compare the reasons for selection and explore the direct student experiences with artificial teeth used in two pre-clinical fixed prosthodontics post-core technique teaching programs conducted in consecutive years. Fourth year undergraduate dental students who had completed the fixed prosthodontics pre-clinical program were invited to complete an anonymous online surveys. Information was requested on the use and direct student experiences with artificial and natural teeth for post-core techniques. Quantitative data was summarised and qualitative data was clustered into topics. The reasons for selection and use of artificial and natural teeth were compared within and between the two programs. 36% of 70 respondents in 2020 chose to use one or more artificial teeth for the post-core exercises in the pre-clinical program compared with 94% of 77 respondents in 2021 (p< .05). The use was driven by difficulty in sourcing appropriate natural teeth. Respondents reported "ease of use" as the dominant positive user experience with the main negatives being "unrealistic simulation of natural teeth" and "different surface texture/feel when cutting." Artificial teeth were reported to provide an appropriate and realistic simulation experience compared with extracted natural teeth and were easier to source. Students focussed on the practicalities of sourcing artificial teeth, associated costs and ease of use ahead of conceivable educational benefits. Cost limited the more widespread use of artificial teeth.

The use of artificial teeth for post-core techniques in a pre-clinical fixed prosthodontics undergraduate teaching program: an evaluation of student experience

Aim: The use of artificial teeth in pre-clinical simulation clinic teaching of post-core techniques has clear educational benefits for students and staff. This study explored the reasons for selection and direct student experiences with artificial teeth in a recently conducted pre-clinical fixed prosthodontics post-core technique teaching program. Materials and Methods: An online anonymous survey was delivered to fourth year undergraduate dental students who had completed the fixed prosthodontics pre-clinical program seeking information on the choice of artificial or natural teeth and direct experiences. Quantitative data was summarized and qualitative data was clustered into topics. Results: A 100% response rate was received. Twenty-five (36%) of 70 respondents chose to use one or more artificial teeth for the post-core exercises which was predominantly driven by difficulty in sourcing appropriate natural teeth (59%) rather than educational benefit (13%). Forty-five (64%) chose not to use artificial teeth largely due to the cost of the teeth (49%). Direct student experiences in using the artificial teeth for post-core exercises were generally positive. Conclusions: As the first known research of its kind, within the limitations of this study, artificial teeth provided an appropriate and realistic simulation compared with extracted natural teeth and were easier to source for the post-core exercises of the pre-clinical fixed prosthodontics program. More widespread use of artificial teeth was limited by cost.

A new teaching model with artificial teeth containing simulated pulpal tissue

This study aimed to evaluate the use of artificial teeth for endodontic training for dental students. The following aspects of the artificial teeth were approved by the endodontists in Isfahan University of Medical Science: internal and external anatomy; coronal pulp chambers regarding their size, shape, and canal path; the root canals regarding their size, shape, and position; filling the pulp chamber and root canals by considering the texture, quantity, color, and ease of handling; and resin hardness and visualization of the radiographic image. The results showed favorable opinions regarding the internal and external anatomy, coronal pulp chamber, root canal (s), handling, and radiographic imaging. The contents of the pulp space and hardness of the teeth were satisfactory. The artificial teeth tested have the potential to replace the natural teeth in preclinical training.

Percepção de docentes de Odontologia sobre o uso de dentes humanos como recurso educativo em atividades pré-clínicas

O estudo teve por objetivo avaliar a percepção de docentes de Odontologia em relação à utilização de dentes humanos extraídos e dentes artificiais em atividades pré-clínicas. Utilizou-se um questionário com perguntas objetivas e subjetivas aplicado aos professores cirurgiões-dentistas do Curso de Odontologia Centro Universitário de Anápolis - UniEVANGÉLICA. Dos 50 professores que correspondiam aos critérios de elegibilidade, obteve-se taxa de resposta de 76%. A média do tempo de formado dos docentes é de 20±9,7 anos e a média do tempo de docência de 17±10,5 anos. Quando questionados se dentes humanos deveriam ser utilizados como recursos educativos, a maioria (89,4%) respondeu que sim e em relação à aquisição de habilidades psicomotoras dos estudantes 68,4% acreditam que os dentes humanos são mais vantajosos. Citaram como desvantagem do uso aspectos relacionados à biossegurança (36,8%), dificuldade para obtenção dos dentes (21%), riscos de comercialização (15,7%) e aspectos éticos (15,7%). A maioria dos docentes de Odontologia do curso avaliado entendem que o uso de dentes humanos em atividades pré-clínicas tem maior potencial pedagógico, além de favorecer o desenvolvimento de habilidades motoras em comparação ao uso de dentes artificiais.

Pre-clinical endodontic education outcomes between artificial versus extracted natural teeth: a systematic review.

To compare the educational outcomes using artificial teeth versus extracted teeth for pre-clinical endodontic training. Literature searches of PubMed, Scopus, Cochrane Library, Trip Database, Web of Science and Open Grey databases were conducted from their inception until November 2018 with no language restriction. Hand searching of most likely relevant journals was performed. The review followed the PRISMA guidelines. Studies that compared pre-clinical endodontic training using extracted teeth and artificial teeth were included. The quality of included studies was appraised by Joanna Briggs Institute Critical Appraisal tools. The findings were tabulated and summarized according to their outcomes with distinct narrative syntheses. Five studies were included. The component studies included 359 operators in total, mainly consisting of undergraduate students (97%, n=349) and 10 endodontists (3%). Forty-seven per cent (n=170) operated on artificial teeth only, whilst 19% (n=67) worked primarily on extracted teeth, with the final treatment outcome being evaluated by independent observers using objective criteria. Operators in two studies (34%, n=122) used both artificial teeth and ET and compared their experiences in surveys. Regarding technical outcomes, no significant differences between training with artificial teeth and extracted teeth were found, but the performance tended to be better in artificial teeth than extracted teeth. Operators trained solely on artificial teeth appeared to be adequately educated for subsequent root canal treatment (RCT) in the clinical setting. Due to the scarcity of research on the topic overall, and the methodological variation between the studies, it was not possible to perform a quantitative analysis (meta-analysis). Based on the available evidence, the use of artificial teeth for pre-clinical endodontic training achieved similar educational outcomes compared to extracted teeth. However, the experiences reported by the operators diverged. Further studies assessing other artificial teeth available in the market testing other RCT procedures are necessary.

Tooth Loss-associated Cognitive Impairment in the Elderly: A Community-based Study in Japan.

Objective Dementia is a major cause of disruption for a healthy life expectancy in Japan. It has been suggested that the number of teeth is a modifiable risk factor for cognitive impairment and dementia. We therefore examined the possible association between the cognitive function and the number of natural and artificial teeth in community-dwelling Japanese elderly individuals. Methods Among the participants in our prospective, community-based study, 210 elderly individuals (103 men and 107 women; 78.1±4.9 years; mean age±standard deviation) underwent both dental examinations and a Mini-Mental State Examination (MMSE), as well as various medical checkups, in 2016 and 2017. Results The number of natural teeth was significantly associated with an individual's MMSE score. The percentage of cognitively normal subjects (MMSE scores: 27-30) decreased significantly with a decrease in the number of natural teeth. Among the MMSE items, the calculation ability was significantly and independently associated with the number of natural teeth. Regression was calculated as the predicted score of MMSE =21+0.3×(years of schooling)+0.1×(number of natural teeth). Among individuals with 19 or fewer natural teeth, those who had a total of 20 teeth or more, including both natural and artificial teeth, had significantly higher MMSE scores than those who had 19 or fewer natural and artificial teeth combined. Conclusion The number of natural teeth was significantly associated with the cognitive function, especially the calculation ability, and the use of artificial teeth was associated with the preservation of the cognitive function in community-dwelling elderly individuals.

Assessment of the Technical Quality of Root Canal Treatment in Pre-clinical Endodontic Training Comparing Artificial Teeth to Extracted Natural Human Teeth

Introduction: Extracted natural human teeth were used exclusively for preclinical endodontictraining. However, an alternative method involves the use of artificial teeth aiming to overcomethe limitations in natural teeth. This study aimed to radiographically evaluate the technical qualityof preclinical single root canal treatments performed by undergraduate dental students using twoalternative models; artificial teeth and extracted natural human teeth.Materials and methods: Cross-sectional study, 228 single rooted teeth in academic years2017- 2018 were obtained from the preclinical practice of undergraduate program in endodonticsat the school of dentistry, King Abdulaziz University, Jeddah, Saudi Arabia. Four observers wereasked to independently evaluate the radiographic quality of the root canal fillings according to threeparameters: Filling length, density (homogeneity), and taper of the filling in the root canals.Results: There were no significant correlation between the type of teeth and all three parameters;length, density, and taper of the root canals fillings. In addition, there was no statistically significantdifference between adequacy of the root canals fillings and the type of teeth (P. value: 0.455).Extracted natural human teeth showed overall 10% adequate filling, 77.7% moderately filling,and12% poorly filling. Meanwhile, artificial plastic teeth showed overall 13% adequate filling,81.6% moderately filling, and 5% poorly filling.Conclusion: Artificial teeth might be suitable for preclinical endodontic training but cannottotally substitute the requirement to learn with extracted natural human teeth as part of preclinicalendodontic training. They could be incorporated with natural teeth.

Different Occlusal Schemes in a Persistent Protruding Complete Denture Wearer.

Different types of artificial teeth and occlusal designs can be used in complete dentures. Bilateral balanced occlusion, lingualized occlusion, canine guidance, and monoplane are the main occlusal designs; however there is no agreement on which tooth arrangement is ideal for achieving success in complete dentures. This report presents an alternative for persistent involuntary protruding complete denture wearers through the use of artificial teeth with higher cusps. Due to an old and worn pair of complete dentures, the patient had the habit of protruding. New dentures were made with Biotone artificial teeth and in the trial session, the patient would still protrude. A new set was made with Premium artificial teeth, which present higher cusps. With these dentures, the involuntary protrusion did not occur. From the delivery to the follow-up sessions, the patient stopped protruding.

Critical analysis of artificial teeth for endodontic teaching

The purpose of this study was to evaluate the use of artificial teeth for endodontic teaching. A questionnaire was prepared and submitted to 18 professors of Endodontics from different Brazilian universities to evaluate the following features of five cloudy resin artificial teeth: internal and external anatomy; coronal chambers regarding their size, shape and canal path; root canal regarding their size, shape and position; fulfillment of the pulp chamber and root canals by considering the texture, quantity, color, and ease of handling; resin hardness and visualization of the radiographic image. The results presented favorable opinions, in terms of internal and external anatomy, coronal pulp chambers and root canal and handling and radiographic imaging. The contents of the pulp space and hardness of the teeth were considered satisfactory. The average grade assigned to the artificial tooth quality was 8.4, in a 0-10 scale. In conclusion, the artificial teeth have potential to replace the natural teeth in endodontic teaching; however, improvements are still necessary to reach a better quality model.

The Use of Artificial Teeth by the Ancients

THIS is not a new discovery, as stated in Cosmos (see NATURE, April 16, p. 564). Cicero, De Legib. 11., 24, quotes a law from the Twelve Tables forbidding the combustion or burial of costly golden articles, but allowing an exception in favour of “teeth fastened with gold” (Quoi auro dentes vincti escunt, &c.).
