Abstract
Aim: In this study, it was aimed to evaluate the effect of angular parameters, which are a part of mandibular morphometry, on gender assessment with the help of cone beam computed tomography (CBCT).
 Material and Methods: A total of 197 healthy adults, 100 females and 97 males, aged between 18-68 years were included in our study. Ten angular parameters of the mandible were evaluated using CBCT. Independent samples t-test was used to compare the gender for each of the age and angle measurements. In addition, the success of the angles in gender diagnosis was examined by a stepwise linear canonical differential analysis. Statistical significance level was accepted as p0.05). In order to eliminate the effect of age difference, a total of 11 variables including age were comprised in the model, and discriminant analysis was performed with the stepwise variable elimination method to select only the variables that could make significant gender discrimination. As a result of variable elimination, we found that the overall correct classification success of the discriminant function, which includes a total of 4 angles, sexually dimorphic right α angle, left Go angle, right β angle, and left α angle, was 71.5%.
 Conclusion: This study showed that among the angular parameters of the mandible, the left Go angle being the highest, the right α angle, right β angle and left α angles have sexual dimorphic properties, and gender estimation can be made with 71.5% overall accuracy with the discriminant function containing these parameters.
