Abstract Objective To explore the effect of WeChat combined with problem-based learning (PBL) model in undergraduate clinical practice teaching of periodontology. Methods Forty undergraduates interns were selected as the research objects during clinical practice in the Department of Periodontology of School of Stomatology of the Fourth Military Medical University between July 2018 and June 2019. Simple random method was used to divide the patients into the experimental group (n = 20) and the control group (n = 20). The experimental group adopted WeChat combined with PBL teaching mode, while the control group adopted traditional lecture-based learning teaching mode. The internship lasted for 8 weeks. At the end of the internship, the teaching was evaluated in two ways, namely, subject examination and student satisfaction survey. Results The total score of the experimental group was higher than that of the control group, and the scores of oral examination, medical record writing and standardized operation were higher than those of the control group, with statistically significant differences (P < 0.05). The total scores of boys and girls in the experimental group were higher than those in the control group, and the difference was statistically significant (P < 0.05). Ninety-five percent of the students in the experimental group were satisfied with the joint teaching mode, and 85 percent were very satisfied. Conclusion In periodontal clinical practice teaching, WeChat combined with PBL teaching mode is easier to arouse students′ interest in learning, inspire students′ independent thinking ability, greatly improve students′ practice effect, and obtain good clinical teaching effect, which should be widely applied.
