Abstract: Objective To establish the entrustable professional activities (EPAs) for operative dentistry and endodontics in oral medicine residency training. Methods Based on literature research, an expert consultation questionnaire on EPAs for the operative dentistry and endodontics in standardized residency training of oral medicine was developed. From April to June 2024, the Delphi method was used to conduct two rounds of expert letter consultation with 22 experts for screening and optimization the indicators for EPAs. The scores of indicators were evaluated using means and coefficient of variation, and the degree of expert authority and Kendall's W coefficient were used to test the reliability of results. Results The response rates for the two rounds of questionnaires were 95.4% and 100.0%, respectively. The mean scores for all indicators exceeded 3.5, and the coefficients of variation were all below 0.25. The authority coefficients were 0.90 and 0.91 for the two rounds, respectively, and the Kendall's coefficients of concordance were 0.677 and 0.532 for the two rounds (all P<0.001). A total of 13 indicators for EPAs were established, which defined the entrustable level of each EPA that residents should reach at different stages. Conclusions The EPAs for operative dentistry and endodontics in oral medicine residency training have been preliminarily established, which is scientific and reliable,and can provide reference for competency-oriented standardized training and Objective assessment.
