AIM: Mendelian randomization is a more appropriate tool for causal inference, as the main suspected risk factors for periodontitis are difficult to test by randomized controlled trials due to ethical or feasibility issues. This study aimed to evaluate potential causal relationships between 50 known and suspected factors and periodontitis risk by a two-sample Mendelian randomization study and meta-analysis. METHODS: By utilizing the databases of the Gene-Lifestyle Interactions at Dental Endpoints (GLIDE) consortium and the Finnish Genetics (FinnGen) consortium, 25 obesity-related indicators (BMI, birth weight, weight, height, waist-hip ratio, waist circumference, hip circumference, 18 body fat percentage or fat-free mass factors), eight hormone-related indicators (estradiol levels, total testosterone levels, sex hormone-binding globulin, age at menarche, age at menopause, three bone mineral density factors), five lifestyle factors (smoking, alcohol drinking, sleep duration, morning/evening chronotype, years of schooling), three dietary factors (coffee, tea, fruit), six blood biomarkers (fasting glucose, high-density lipoprotein cholesterol [HDL cholesterol], low-density lipoprotein cholesterol [LDL cholesterol], total cholesterol, serum 25-hydroxyvitamin D levels, hemoglobin A1c [HbA1c]), and three diseases (hypertension, type 2 diabetes, COVID-19). The odds ratios (ORs) and 95% confidence intervals (CIs) associated with the risk of periodontitis were estimated for each trait ...
