Role of mandibular anatomical structures in sexual dimorphism in Turkish population: A radiomorphometric CBCT study

Sex determination is one of the primary concerns of forensic science. The cranial bones, pelvis, and mandible have been used for determining the sex of specimens. Because the mandible is robust and sexually dimorphic, studies have evaluated its metric and morphological traits. This study was designed as a retrospective study involving cone beam computed tomography (CBCT) images to assess sexual dimorphism of the mandible in the Turkish population. Total sample group consisted of 176 bimaxillary CBCT scans (71 males and 102 females; ages 19–67 years). Sixteen mandibular parameters were measured using two different software programmes. Measurements were recorded in various planes of three-dimensional (3D) reconstructions of the scans. All parameters aside from SIMaCD were found to be statistically significant. The highest diagnostic accuracy rate was associated with IMaF, and the overall accuracy rate of the fourteen parameters was found to be 80%.
