Evaluation of Bone Quality in Patients With Bruxism

Abstract

Abstract Aim: The aim of this study is to evaluate the mandibular bone quality using radiomorphometric indices and Fractal dimension [FD] analysis in orthopantomography [OPG]. Material and Methods: OPGs of 100 patients, 50 bruxers and 50 non-bruxers, were included in this retrospective study. Values ​​such as mental index [MI], panoramic mandibular index [PMI], antegonial notch depth [AND], gonial index [GI], antegonial index [AI] and mandibular cortical index [MCI] were calculated in OPG. Eight bilateral areas of interest [ROI] were selected on ort for FD analysis: ROI 1, mandibular condyle; ROI 2, mandibular ramus; ROI 3, mandibular angulus; ROI 4, mandibular mental area. Results: MI, PMI and AND values ​​were higher in bruxers than in the control group [p<0.05]. There is no statistically significant difference between AI and MCI measured on the right and left sides between bruxism patients and control group patients [p>0.05]. As a result of the calculations, the FD values ​​of the left condyle [p=0.02] and left angulus [p=0.03] areas showed a statistically significant difference between individuals with and without bruxer. No statistically significant difference was found in the FD measurements calculated from the ramus and mental areas on the right and left sides [p>0.05]. The relationship between FD values ​​and gender in these areas was examined and no statistically significant difference was found [p<0.05]. Conclusions: MI, PMI and AND measurements can be used in the diagnosis or follow-up of bruxism. There is no difference in mandibular cortical bone height in patients with and without bruxism according to AI and MCI. The mean GI measured on the right side differed between groups. FD values ​​of the mandibular trabecular bone are affected by bruxism in the right condyle and right angulus areas.
