Prospective Randomized Controlled Study to Evaluate Combining Video Feedback Teaching with Virtual Simulation for...

Area of Science:

• Dental Education
• Restorative Dentistry
• Medical Simulation

Background:

• Traditional dental education relies on conventional methods for preclinical training.
• Effective training in ceramic veneer tooth preparation is crucial for dental students' clinical success.
• Virtual simulation and video feedback offer potential enhancements to traditional teaching.

Purpose of the Study:

• To evaluate the impact of combining video feedback teaching with virtual simulation for ceramic veneer tooth preparation.
• To compare the effectiveness of this innovative approach against traditional teaching methods.
• To assess student satisfaction and engagement with the new teaching methodology.

Main Methods:

• 40 dental students were randomly assigned to a control group (traditional teaching) or a study group (video feedback + virtual simulation).
• Tooth preparation skills were assessed at 1, 2, and 3 months post-training.
• Objective performance metrics (preparation scores, simulation accuracy) and subjective feedback (satisfaction, engagement) were collected.

Main Results:

• The study group showed significantly lower operating position scores (14.9 ± 2.07) compared to the control group (17.1 ± 1.66).
• Virtual simulation accuracy scores were significantly higher in the study group (89.5 ± 4.2).
• Student satisfaction and engagement scores were significantly higher in the study group (all p < 0.05).

Conclusions:

• Video feedback combined with virtual simulation provides a superior practical training effect for ceramic veneer tooth preparation.
• This integrated teaching method improves objective performance and enhances student subjective experience.
• The findings support the adoption of technology-enhanced learning in dental preclinical education.
