Abstract

Although human sex difference are now better known worldwide, there are few osteometric studies designed for sex assessment in Egyptians. The current study is the first to be conducted on this population to evaluate sex determination using osteometric mandibular measurements. By the use of spiral CT scan with three dimension reconstruction modality six mandibular measurements were assessed in 330 person (165 males and 165 females). These were subjected to statistical analysis. Many variables showed significant differences and included: bicondylar breadth, gonial angle and minimum ramus breadth. The study concluded that the overall predictive accuracy of this prediction model was 83.9% for whole studied persons. The correct predictive accuracy was 83.6% in males and 84.2% in females.
