Abstract: Objective: To evaluate teaching effect of virtual simulation tutoring system in standardized residency training of dentistry and to improve the application of virtual simulation tutoring system. Methods: Qualitative research method was used in this study. Semi-structured interview was conducted in 12 residents who received standardized residency training in the Department of General Dentistry, Peking University School and Hospital of Stomatology from September 2020 to September 2022. They received virtual simulation tutoring system dental preparation teaching. After the interview, the interview recordings were transcribed, and the transcribed text was analyzed assisted by NVivo 11.0 software. Results: From the perspective of residents, the standardization of operation process, the standardization of evaluation process and the promotion of autonomous learning were the three advantages of virtual simulation tutoring. The difference between the system and clinical practice and the system program were the shortcomings. On the whole, the residents' positive emotional attitudes towards virtual simulation tutoring system were greater than negative ones. Conclusions: Virtual simulation tutoring system is the development direction of intelligent education in the dentistry, and residents have a higher acceptance of this new teaching mode. It is suggested that the system be further improved and optimized in order to effectively improve the teaching quality and promote its application in the future.
