Determination of Sex by Morphometric Study of Dry Adult Human Mandible

Abstract

Introduction: An important aspect of medico legal and anthropological work is the identification of human skeletal remains. After death, bones often survive decay and provide evidence of a person's sex. As the strongest bone in the facial skeleton, the mandible often resists post-mortem damage and provides important information about sexual dimorphism. Objective: Assessing the morphometric changes in the dry human mandible to ascertain sex is the study's goal. Methods: From January to December 2017, a descriptive study took place at the Department of Anatomy, Sylhet MAG Osmani Medical College, Sylhet. By using a convenient sampling method 50 adults, dry, complete, undamaged human mandibles were selected. Results: A variety of measurements were made, recorded as Mean ± SD, and examined using SPSS Statistics 21's unpaired t-test. The results showed statistically significant differences between both genders in mandibular angle, mandibular ramus's length, and mandibular foramen. Conclusion: This research has shown that it is possible to determine the gender of the mandible by using different metrical parameters as an additional tool to establish a person's identity.
