Abstract

Background and Aim: Three-dimensional (3D)-printed endodontic tooth models have been proposed as alternatives to extracted teeth in preclinical education. This study aimed to compare the educational value and usability of three commercially available 3D-printed endodontic training models based on undergraduate dental students’ perceptions.
Materials and Methods: Fifty-seven dental students with prior preclinical endodontic training performed standardized root canal procedures on three different mandibular molar models produced by stereolithography using distinct photopolymer resins. Each student completed a structured questionnaire evaluating morphological features, material characteristics, radiographic properties, and overall clinical handling. Responses were recorded using Likert-type scales. Quantitative data were analyzed using Friedman’s Two-Way Analysis of Variance by Ranks with a significance level of 0.05. Open-ended responses were evaluated thematically.
Results: Friedman test revealed statistically significant differences among the models across several domains (p<0.05). The Edudent model had the highest median scores in anatomical realism, material hardness, apical feedback, and file handling (p<0.001). The Ancorax model exhibited superior radiographic contrast (p<0.001), while the BTech model consistently showed lower performance. Qualitative feedback emphasized the need for enhanced internal canal complexity, radiopacity and tactile resistance.
Conclusions: Educational performance varied significantly among the tested models. Continued refinement is necessary to improve clinical realism and training outcomes.
