Resumen
Objectives: The causes of exostoses, such as mandibular/maxillary torus, include bruxism, occlusal force, genetics, and environmental factors. This study investigated the correlation between mandibular/maxillary torus and periodontitis.
Method and materials: A total of 478 patients over 20 years of age who visited the general dental clinic from 2001 to 2014 were enrolled in the study. Clinical data, including periodontal probing depth, bleeding on probing, and DMFT index, were evaluated. The general condition of the patients, including back pain, shoulder stiffness, and history of smoking, was evaluated via medical interviews. Logistic regression analysis was performed to assess the association between mandibular/maxillary torus and patient characteristics.
Results: Apart from sex, no statistically significant differences were observed between the torus and the other patient characteristics. In addition, no significant association was found between the presence of a torus and the number of teeth with a probing depth of > 6 mm.
Conclusion: These findings suggest that the mandibular/maxillary torus does not contribute to periodontitis. Additional longitudinal studies are warranted to elucidate the complex interplay between genetic predisposition, environmental factors, and mechanical stress in the development of the torus and its potential impact on periodontal health.
