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

This study aims to analyze the impact of video feedback teaching combined with virtual simulation for ceramic veneer tooth preparation. A total of 40 prospective dental students who were about to start clinical internship in Jiangsu Medical College between April 2024 and July 2024 were randomly divided by convenience sampling into a control group and a study group. The teaching effect was compared at 1, 2 and 3 months after teaching. After the training, the scores of the two groups of tooth preparations were significantly improved compared with those before training, and the scores of the operating positions were significantly reduced compared with those before training. In addition, the operating position scores of the study group (14.9 ± 2.07) were significantly lower than those of the control group (17.1 ± 1.66; p < 0.05). The study group also achieved significantly higher virtual simulation accuracy scores (89.5 ± 4.2) by the end of the training period. There was a statistically significant difference (p < 0.05) in the effectiveness of the two sets of tooth preparations. Questionnaire results indicated significantly higher satisfaction and engagement scores in the study group than in the control group (all p < 0.05). Compared with traditional teaching methods, the application of video feedback teaching combined with virtual simulation technology in the preparation of ceramic veneered teeth has a better practical training effect, as supported by both objective performance metrics and subjective learner feedback.
