Summary

This study aims to evaluate the effectiveness of a combined teaching method using video feedback and virtual simulation for training dental students in ceramic veneer tooth preparation, compared to traditional teaching methods. The hypothesis is that this integrated approach will lead to better acquisition of practical skills.

The study is designed as a prospective, randomized controlled trial. Forty dental students about to begin their clinical internship will be randomly assigned to one of two groups. One group will receive traditional teaching involving lectures and instructor-led demonstrations on dental simulators. The other group will receive the experimental intervention, which combines the use of a virtual simulation training module with video recording of hands-on practice sessions. In the experimental group, students will review their recorded performances for self and peer assessment under instructor guidance.

All participants' ceramic veneer preparation skills will be assessed before the training begins. Their skills will then be re-evaluated at 1 month, 2 months, and 3 months after completing the training. The assessments will focus on two main areas: the ergonomic quality of the student's operating posture and the technical quality of the tooth preparation they perform on a simulator.

  • Ceramic Veneer
  • Head Simulator
  • Video Feedback Teaching
  • Virtual Simulation

Interventions

BEHAVIORAL

Traditional Teaching Method

The intervention consisted of a 20-minute theoretical instruction on ceramic veneer preparation, followed by a 20-minute live clinical demonstration by an instructor. Students then engaged in supervised and independent hands-on practice sessions (100 minutes each on two consecutive days) using head simulators, during which the instructor provided immediate feedback.

BEHAVIORAL

Video Feedback Teaching combined with Virtual Simulation

The intervention included a 20-minute theoretical instruction and completion of a mandatory virtual simulation module. After a live instructor demonstration (recorded on video), students practiced in pairs, recording each other's procedures. They then conducted peer critiques by reviewing the videos. An instructor-led group video review session provided further feedback. A second day involved additional practice with instructor guidance.
