Gonial Angle as a Determinant of Gender, a Panoramic Study in a Sample of Saudi Population

Introduction: Sex determination is a valuable factor in forensic dentistry. The present study aims to assess the possibility of using gonial angle as a determinant of gender through a retrospective panoramic study, in a sample of Saudi population.

Materials and Method: A 342 digital panoramic radiographs (179 males and 163 females) of adult dentulous Saudi patient attending university dental hospital, Qassim university, KSA were assessed in this studywere assessed in this study. Gonial angle measurements were calculated bilaterally.

Results: The mean values were calculated and compared between male and female subjects using SPSS (V. 22). Level of significance was set at 0.005. The mean values of the external gonial angle measured using the panoramic radiographs were 125.50 ± 5.95° and 127.45 ± 6.77°, respectively.

Conclusion: In the present study, statistically significant difference was observed between the gonial angles measured in between males and females using panoramic radiographs. Gonial angle can be considered reliable for gender determination.
