Background: A critical component of identification is determining sex. The skull is regarded as the second-best indicator of gender. The mandible, which is the most dimorphic, largest, and strongest bone in the skull, may be important for determining gender in situations where a whole dry skull cannot be found. Cone beam computed tomography (CBCT), according to studies, was found to be better than conventional techniques. A low radiation dose can be obtained by using a CBCT equipment to produce 3D images that are undistorted and of high quality. The goal of this study was to measure the morphometric parameters of the 3D mandible models in the Upper Egyptian population and to assess how well measures could be used to identify gender.
Purpose: assess accuracy of various parameters of the mandible for sex determination by Cone beam computed tomography (CBCT).
Material and Methods: CBCT radiographs of 500 mandibles of males and females patient with varying ages range from (18_60) years were taken from database of outpatient clinic of oral and maxillofacial radiology department, Faculty of Dentistry, Minia University. Five linear parameters were measured in mm using the mouse-driven method.
Results: It was found that all variable of mandible on CBCT models showed a statistically significant difference among the sex (p < 0.05).
Conclusions: Mandibular measurements can be useful tool for sex determination
