Objective: Bruxism is a parafunctional habit characterized by clenching and/or grinding the teeth. Bruxism can occur during sleep or while awake. It is a clinically important phenomenon because we commonly encounter it in the adult population. Opinions about the causes of bruxism are many and varied. Malocclusion, sleep disorders, sympathetic or parasympathetic nervous system activation, alcohol, tobacco, medication, parafunctional habits, temporomandibular joint disorders, high anxiety level, psychiatric disorders and stress are among the possible etiological factors. The consequences of bruxism, in addition to effects such as tooth wear and pain, may also include changes in tooth movement, oral soft tissues and jaw bone. The aim of this study is to evaluate the effects of bruxism on the antegonial and gonial regions of the mandible, which are the attachment points of the chewing muscles, using panoramic radiographic images. Material and Methods: A total of 238 people, 106 of whom had bruxism and 132 of whom did not have bruxism, were included in our study. In panoramic radiograms, gonial angle, antegonial angle and antegonial depth were measured on the right and left sides of the mandible using the Image J program. Additionally, the presence of bone apposition in the gonial region was evaluated. Results: While gonial angle and antegonial angle were higher in women; antegonial depth was higher in males. The presence of exostosis in the gonial region was statistically significantly higher in men. It was observed that the antegonial depth measurements in the group with bruxism were significantly lower than in the group without bruxism. There was no significant difference in bone apposition in the gonial region between individuals with and without bruxism. Conclusion: This study shows that there is a remodeling in the lower jaw according to bruxism. This reshaping appears to be specific to the region.
