Objective To explore the effectiveness of first-person perspective (FPP) video teaching in the clinical operative skills training of tooth preparation for dental residents. Methods From January 2020 to November 2022, 20 residents in the Department of Stomatology at Beijing Anzhen Hospital, Capital Medical University were enrolled in this study. A randomized controlled trial was conducted, dividing the participants equally into an experimental group (FPP video) and a control group (third-person perspective). The teaching outcomes were compared by objectively scoring the three-dimensional dental preparation volume using fitted scan data, along with subjective evaluations from the participants. Statistical analysis was performed using one-way ANOVA. Results The experimental group achieved significantly higher overall objective scores [(54.2±1.0) points] compared to the control group [(43.0±2.3) points], P<0.001. Subjective evaluations of the instructional videos' effectiveness were also higher in the experimental group [(86.6±14.1) points vs. (67.6±11.8) points, P<0.05]. Conclusions FPP video teaching enhances residents' comprehension of key dental preparation techniques and improves operational proficiency, with higher satisfaction rates in standardized residency training.
