Abstract: Objective: To evaluate the effect of scenario simulation combined with case-based learning (CBL) in improving doctor-patient communication skills of residents of general dentistry. Methods: This study selected eight typical and disputed clinical cases to design physician-patient communication scenarios, establishing a simulated case database for dental communication training. The research was carried out on 17 residents of general dentistry from Department of General DentistryⅡ, Peking University School and Hospital of Stomatology from September 2023 to August 2024. After completing the theoretical knowledge of doctor-patient communication, the students’ doctor-patient communication abilities were evaluated by the teachers using the set elicit give understand end (SEGUE) framework. After the completion of the scenario simulation combined with CBL teaching, the teachers evaluated again. At the same time, students were asked to evaluate the course by questionnaire. Results: The total score of the initial evaluation of the scale was (18.00±2.29), and the total score increased to (22.41±1.54) after the training, and the difference was statistically significant (P<0.05). The scores of the residents in the preparation stage, information collection stage, understanding the patient stage, and the end of the inquiry stage were all improved statistically. Most of the students thought that the course was necessary, and they had a strong sense of involvement and promotion. Conclusion: Scenario simulation combined with CBL teaching mode can improve the participation and the communication skills of the residents in the standardized training of general dentistry, and can be popularized and applied in the training base in the future.
