Abstract

Objective: To evaluate the accuracy of bizygomatic distance and intermaxillary distance for sex estimation among a group of adult Egyptian population using Cone Beam Computed Tomography (CBCT).
Material and Methods: One hundred retrospective Cone Beam Computed Tomography scans of adult Egyptian individuals were included in this study (Fifty males and fifty females). The bizygomatic distance and intermaxillary distance were measured on axial Cone Beam Computed Tomography images. All the measurements were statistically analyzed in relation to sex.
Results: Both study measurements (bizygomatic distance and intermaxillary distance) were found to be higher in males than that in females with statistical significance difference (p < 0.05) . Furthermore, discriminant function analysis showed that the highest overall prediction rates were found in the univariate bizygomatic distance model for both sexes.
Conclusion: Using Cone beam Computed Tomography, bizygomatic distance may be considered a strong sexual dimorphic tool in Egyptian adult population and should continuously be considered for sex estimation through human identification.
