Correlation between mandibular/maxillary torus and periodontitis: a cross-sectional study.

This article investigates the correlation between mandibular and maxillary tori—bony exostoses in the oral cavity—and periodontitis severity in a cross-sectional study of 478 patients aged over 20 years. Clinical assessments, including periodontal probing depth and bleeding on probing, alongside patient characteristics such as bruxism and smoking history, were analyzed using logistic and linear regression models. The study found no significant association between the presence of mandibular or maxillary tori and periodontitis severity, measured by the number of teeth with probing depths greater than 6 mm. While maxillary tori showed a significant association with sex and all tori collectively correlated with back pain, these factors did not relate to periodontal disease severity. The authors conclude that mandibular and maxillary tori do not contribute to periodontitis and recommend longitudinal studies to further explore genetic, environmental, and mechanical influences on torus development and periodontal health.
