dc.description.resumoObjective: The aim of this study was to evaluate new radiomorphometric indices in cone beam computed tomography (CBCT) for assessing bone mineral density (BMD) status in postmenopausal women. Study design: Mandibular inferior cortical bone thickness was evaluated in 48 postmenopausal women in cross-sectional images at 4 sites: (1) symphysis (S): cross-sectional image equidistant from the centers of the right and left mental foramina (MF); (2) anterior (A): 10 mm anterior to the MF; (3) molar (M): 10 mm posterior to the MF; and (4) posterior (P): 25 mm posterior to the MF. Participants underwent dual-energy x-ray absorptiometry and were divided into normal, osteopenia, and osteoporosis groups. In the study, t tests with Bonferroni correction were conducted. Statistical significance was set at P < .017. Receiver operator characteristic (ROC) analyses were performed. Results: Mean S index was significantly lower in osteoporosis than in osteopenia (P = .005). Mean M index was significantly lower in osteopenia (P < .001) and osteoporosis (P = .001) than in normal individuals. Mean P index was significantly lower in osteoporosis than in normal patients (P = .008). ROC values ranged between 0.643 and 0.740. Cortical thicknesses separating normal from abnormal varied from 1.73 mm to 3.37 mm. Conclusions: M and P indices in CBCT may be useful for identifying low BMD in postmenopausal women.pt_BR
