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

Abstract

Aim: 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.

Methodology: 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.

Results: 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.

Conclusion: 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.
