Evaluating the effectiveness of a novel training model in dental preclinical regenerative endodontic education

Regenerative 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.

A 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.

The 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.

The 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.
