Each individual was subjected to clinical examination anddigital true lateral cephalometric radiograph that had been analyzed using AutoCAD 2007 software computerprogram to determine sixteen linear and ten angular measurements. Descriptive statistics were obtained andindependent samples t-test was performed to evaluate the gender differences in different classes. ANOVA test asused to compare the measurements among the skeletal classes in each gender, while Pearson’s correlationcoefficient test was used to determine the relations among ramal length and width with other measurements in allclasses.Results and Conclusions: All of the linear measurements were significantly higher in males than females. On the otherhand, the angular measurements showed non-significant gender difference except for SN-PP angle in class II group.ANOVA test showed statistically significant difference in upper gonial angle, Y-axis angle and the mandibular length.Ramal length and width correlated significantly with PFH, SN-MP angle and Co-Gn.
