Objective To explore the teaching effect of Mendelian randomization analysis combined with problem-based learning (PBL) teaching mode in "Periodontology". Methods Two classes of undergraduate students majoring in dentistry from Ningxia Medical University in 2022 were selected as the research subjects. Among them, 45 students who received classroom teaching combined with PBL teaching mode were set as the control group, and another 45 students who received Mendelian randomization analysis combined with PBL teaching mode were set as the experimental group. Compare the teaching effectiveness of two groups. The test scores of the experimental group (objective questions, short answer questions, case analysis) were higher than those of the control group (P<0.05). The classroom performance scores of the experimental group were higher than those of the control group (P<0.05). Conclusion Mendelian randomization analysis combined with PBL teaching mode can improve the teaching effectiveness of "Periodontology" and promote the development of students comprehensive abilities.
