“…Dental simulators have been created with different materials [ 12 , 13 ]. Three-dimensional-printed resin simulators were first developed for pedagogical purposes [ 14 ], and it was reported that their use had positive effects on students’ self-confidence [ 15 ]. Three-dimensional-printed simulators have not yet been used in comparison with human teeth during experimental mechanical tests.…”

Endocrowns are designed to restore endodontically treated teeth with root canal treatment (Rct). Recently, endocrowns were proposed for teeth treated with full pulpotomy (FP). No data exist on in vitro evaluations for this combination. This study aimed to evaluate the mechanical behavior of pulpotomy-treated teeth with endocrowns according to different protocols for preparation design and materials and to assess whether 3D-printed resin simulators could be a reliable alternative for human teeth during in vitro strength tests. One hundred and ten extracted natural molars were randomized into 11 groups according to the type of endodontic treatment, the material used, and the design of peripheric preparation. One hundred and ten resin simulators were separated similarly. The samples were embedded in epoxy resin blocks before being subjected to oblique compressive load until failure. For natural teeth, the variance analysis separated two homogeneous groups, one regrouping the endodontically treated or pulpotomy-treated teeth without coronal restoration and the other one regrouping all the other samples, i.e., the untreated teeth (positive controls) and the treated and restored teeth. The strength resistance was lower for the resin simulators than for natural teeth in all groups. Within the limit of this study, strength resistance is not the most important criterion for choosing the type of material, preparation, or endodontic treatment for endocrowns. Resin simulators are not efficient for in vitro strength studies.

AimRegenerative endodontic procedures (REPs) are tissue engineering‐based treatments aimed at regenerating the pulp‐dentin complex. However, these procedures are not widely practiced or well‐known among dentists due to a lack of training. This study aims to develop a practical hands‐on training model for REPs to enhance students' theoretical knowledge and practical skills.MethodologyA cost‐effective, easy‐to‐operate, and reusable training model for preclinical training of REPs was developed. A total of 125 undergraduates were divided into an experimental group (REPs model) and a control group (traditional teaching). The students' theoretical knowledge and operational skills were assessed through examinations and practical assessments. Student perceptions were assessed by questionnaires.ResultsThe experimental group achieved higher scores in theoretical knowledge and operational skills compared to the control group (p < .001). The process evaluation of the experimental group demonstrated a high level of proficiency in executing root canal disinfection steps, with pass rates ranging from 93.5% to 95.2%. Students in both groups perceived the model as valuable for improving critical thinking, stimulating interest, and enhancing their confidence and proficiency.ConclusionThe developed REPs training model is a practical and effective tool for teaching and training regenerative endodontics. It bridges the gap between preclinical and clinical education, enhancing students' confidence and clinical competence.
