| Aim: to assess the accuracy of CBCT sex determination in a population sample from Egypt by utilizing the mental foramen and bigonial distance. Subjects and methods: The mandibles of 500 people were analyzed in this study; 250 of those people were male and 250 were female. Ages 18 to 60 were represented among the participants. Through the use of a mouse-driven method, the dimensions were measured in millimeters. The tests examined the Superior Mental Foramen (SMeF) on the right side of the brain and the Inferior Mental Foramen on the left side. These mental foramina are recognized by different names. (SMeF): the measurement was taken at the midpoint of the lower border, halfway between the superior end of the mental foramen and the point of greatest curvature of the jaw. Conversely, the inferior end of the mental foramen to the midpoint of the lower border distance was used to quantify the maximum curvature of the mandible (IMeF). The length between the gonion on the right and left side was called the bigonial distance. We coded, tabulated, and statistically analyzed the data that we received using IBM SPSS statistics (Statistical Package for Social Sciences) software version 28.0, IBM Corp., Chicago, USA, 2021. Results: Every single assessment revealed a statistically significant disparity between the sexes (p<0.05). With a diagnostic accuracy of 100%, bigonial distance revealed the highest degree of dimorphism. Conclusion: The current research confirms the usefulness of CBCT pictures for sexual dimorphism in anthropometric analysis and forensic medicine, as well as for providing useful information on mandibular measurements. | ||||
