    Introduction: The determination of gender with age becomes essential in forensic studies and medico-legal investigations. Mandible often serves a significant role in the estimation of sex as it is the most sexually dimorphic bone of the various bones of the skull that usually remains intact during recovery of specimens at crime scenes. In this regard, the availability of dry human bones like mandibles may be of utmost importance in studying and developing population definite standards for estimation of gender and age. The purpose of the present study was to analyze the applicability of various mandibular ramus linear measurements and the gonial angle measurements on dry human mandibles as predictors for sex and age. Material and Methods: In the present study, a total of 50 dry human mandibles of unknown sex and without any gross breakage were collected and are subjected for morphometrical analysis and evaluated. All mandibles were serially numbered from 1 to 50. Five mandibular ramus linear measurements such as upper ramus breadth, lower ramus breadth, projective height, condylar ramus height, and coronoid ramus height and gonial angle measurements were performed bilaterally and recorded.Results: In the present study, a total of 50 dry human mandibles of unknown sex and without any gross breakage were collected and are subjected for morphometrical analysis and evaluated. All mandibles were serially numbered from 1 to 80 (40 males and 40 females). In this study, five linear mandibular ramus and gonial angle measurements such as lower ramus breadth, upper ramus breadth, condylar ramus height, projective height, and coronoid ramus height and gonial angle were measured individually on both sides and recorded. Conclusion: The ramus of the mandible showed a great sexual dimorphism and proved to be much beneficial in the estimation of sex and age in forensic investigation, while the gonial angle could aid in estimation of sex alone.
