Abstract

Background: A vital part of forensic anthropology is to differentiate between sexes by morphologic analysis of osseous tissue. One of these osseous structures that displays a significant degree of sexual dimorphism is mandibular bone. Gender variances in the mandibular anatomy, from its height, position of mental orifice, gonial angle, bigonial width and bicondylar breadth have been observed in various studies.This study was aimed at evaluating the sexual dimorphism based on the average length between the upper and the lower edge of the mental orifice to the mandibular lower border and the mandibular height on right and left side of the jaw on digital panoramic radiographs in a sample of Kurdish population of Iraq. Methods: Panoramic radiographs of 460 patients (230 males and 230 females) were included in the study. The length from both inferior and superior margins of mental orifice to the mandibular lower border and the mandibular height in the mental orifice region was measured on both left and right sides. The data was statistically analysed to estimate the differences among the sexes using Independent sample t-test. Results:The mandibular height in the mental orifice region from alveolar crest to mandibular lower border was more in males as compared to the females, this being statistically significant. The length from superior margin and inferior margin of mental orifice to the mandibular lower border and the mandibular height was more in males as compared to females but was not statistically significant. Conclusion: The height of the mandible in the mental orifice region showed significant sexual dimorphism in the sample of Erbil population.
