Aim To compare the educational outcomes using artificial teeth versus extracted teeth for pre‐clinical endodontic training. Data sources 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. Study eligibility criteria, participants and interventions Studies that compared pre‐clinical endodontic training using extracted teeth and artificial teeth were included. Study appraisal and synthesis methods 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. Results 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. Limitations 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). Conclusions and implications of key findings 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.

The investigation aimed to assess the feasibility of creating an interdisciplinary training model simulating endodontic, restorative as well as implantologic treatment procedures by using 3D printing technology. A CBCT scan of the mandible of a real patient was initially taken. The generated DICOM‐data were converted to a STL‐file, which was further processed to design spaces for exchangeable replica teeth, a bone segment and an adapter to fix the model in a mannequin's head. After the manufacturing process, the model was evaluated by dental students performing a root canal treatment, the insertion of a glass fibre post and the insertion of an implant. The workflow allowed a simple and cost‐effective way of manufacturing a single model, which is suitable for several training scenarios in the fields of endodontics, prosthodontics and implantology. The model was rated as being comparable to the real patient situation and offers repetitive treatment simulations. The present workflow is a feasible way of using DICOM‐data and 3D printing for an interdisciplinary training model. The dental schools can design models according to their own curriculum and put the focus on a patient centered education.

Objectives This study explores the practices of obtaining human teeth for teaching and research in Paraguay. The goal of this research is to understand whether the data supports the need to improve ethical training within dental education, including the creation of a human tooth bank (HTB) Methods An observational cross‐sectional study was conducted. Three semi‐structured questionnaires were developed, one for each target population: dental students, dentists in practice, and the general population. The questionnaires were distributed between February and April 2021, using Google Forms Results The main places where human teeth were obtained by a student are dental clinics, followed by cemeteries. 94% of students and 91% of dentists paid for teeth on at least one occasion. There is a willingness on the part of students and dentists to donate collections of teeth, and among the general population to donate their teeth if they are extracted, for both teaching and research use. Note that, 31% of students and 6% of the population are aware of what an HTB is, at the same time only 16% of dentists know how it functions Conclusion The number of respondents who obtain teeth from cemeteries and who pay for their acquisition is high. Both of these practices raise ethical concerns. The implementation of informed consent for the donation of extracted teeth is practically nil; although there is a positive attitude towards its implementation. Also, there is a lack of knowledge about the role of an HTB; although the population expressed a willingness to donate extracted teeth.
