Abstract

 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.
