OBJECTIVE: To examine the prevalence of torus mandibularis (TM) and identify clinical factors associated with its presence.
MATERIALS AND METHODS: A total of 664 Japanese adults over age 60 were studied by means of a questionnaire and clinical examination.
RESULTS: In all, 197 subjects (29.7%) had TM. We found a significant association between the presence of TM and torus palatinus (TP; 45.1% vs. 26.5%, p<0.001). Moreover, occlusal force with TM was significantly higher than without TM (p<0.05). Logistic regression adjusted for age and occlusal force revealed a significant relationship between TM and occlusal force and TP [p=0.005, odds ratio (OR)=2.44; p<0.001, OR=2.66, respectively].
CONCLUSION: This study suggests that there is a relationship between TM and factors related to occlusal factor.
