Abstract：
UNASSIGNED: This prospective study was designed to evaluate the effects of bruxism on mandibular cortical bone using radiomorphometric indices on digital panoramic radiographs.
UNASSIGNED: The mandibular cortical index (MCI), mental index (MI), and panoramic mandibular index (PMI) were measured on digital panoramic radiographs and evaluated for 128 bruxers (66 female, 60 male) and 128 control subjects. The data were analyzed statistically using intraclass correlation coefficients (ICC), Kappa statistics, Chi-square test, Kolmogorov-Smirnov test, independent t-test, and Pearson\'s correlation analysis.
UNASSIGNED: There was no difference between the groups in terms of MCI type (P > 0.05). While mean MI values were significantly higher in bruxers than the control group (P = 0.007), the difference between groups in mean PMI values was nonsignificant (P > 0.05). In both groups, the C1 type was more prevalent in females than in males (P = 0.001). Females showed significantly lower mean MI values than males in both groups (P ≤ 0.040). However, the difference between genders in mean PMI values was not significant (P > 0.05).
UNASSIGNED: MI measurements may be useful when radiomorphometric indices are to be used for the diagnosis or follow-up of bruxism in the mandible. Among radiomorphometric indices, MI and MCI values are affected by gender differences.
