Abstrakt: This study aimed to evaluate sexual dimorphism in Brazilian edentulous individuals using a formula based on mandible-related linear radiomorphometric measurements. A cross-sectional observational study was conducted with 390 panoramic radiographs (PRs) distributed into three age groups (51-60, 61-70, and 71-80 years). PRs were used to obtain linear measurements of the mandible and derived indices (superior and inferior panoramic mandibular indices [s-PMI and i-PMI, respectively], alveolar bone resorption [ABR] index), and the mandibular cortical index (MCI). Sex-related differences (and sex classifications) increased in the oldest cohort. Both s-PMI and i-PMI were shown to be significant in predicting sex in the age group from 71 to 80 years (p = 0.001 and p = 0.003, respectively) and, when considering the mean of the sides, only the s-PMI was significant (p = 0.037). The ABR index was significantly associated with sex (p = 0.004) and not influenced by MCI, and was used to construct a formula for sex estimation, which demonstrated 69.0% accuracy in the age group of 71-80 years. Sexual dimorphism was evidenced by the formula based on the s-PMI, i-PMI, and ABR indices.
