Materials and Methods: This study was carried out on 70 mandibles (43 male, 27 female) which were collected from the department of Anatomy. A total of 140 mandibular foramina (70 left and 70 right) were included in the study. The distance from the center of mandibular foramen to various anatomical land marks were measured. From the center of mandibular foramen to the anterior border of ramus of mandible, From the center of mandibular foramen to the posterior border of ramus of mandible, From the center of mandibular foramen to the inferior borders of ramus of the mandible and From the center of mandibular foramen to the the mandibular notch were measured using digital vernier calipers and data was analyzed using spss 16th version. Results: The results showed that there is a significant difference between the distance from the center of the mandibular foramen to the anterior border and mandibular notch. Stepwise and direct discriminative analysis shows sexual dimorphism with 90% accuracy bearing Wilkin’s lambda and Eigen values as 0.475 and 1.104 respectively. Conclusion: In the present study the sex of the mandible was determined with 90% accuracy by using the distance from the center of the mandibular foramen to the borders of ramus of the mandibles.
