Association between torus mandibularis, self-reported bruxism and occlusion

Abstract

This study was conducted to evaluate the association among torus mandibularis (TM), self-reported bruxism, and occlusion. In total, 212 patients with TM (TM group) and 302 patients without TM (control group) who were treated at Chosun University Dental Hospital from January 1, 2019 to April 30, 2019 were included. Self-reported bruxism, Angle’s classification of upper and lower 1st molar occlusion, and mandibular lateral movement (canine guidance, group function guidance) were investigated and statistically compared. A significant difference was observed in the relationship between TM and self-reported bruxism in the TM group (p<0.001). There was no significant difference in the relationship between TM and occlusion in both groups (p=0.422); however, a significant difference was noted in the relationship between TM and group function guidance in the TM group (p <0.001). There was the association among TM, self-reported bruxism, and group function guidance of mandibular lateral movement.
