Aims and Objectives: (1) To determine the usefulness of mandibular ramus as an aid in sex determination. (2) To evaluate Anteroposterior,superioinferior angle of mandibular condyle. Materials and Methods: A retrospective study was conducted using orthopantomographs of 60 males and 60 females,which were taken using Kodak 8000C Digital Panoramic and Cephalometric System (73 kVp, 12 mA, 13.9 s). The age group ranged between 18 – 45 years. Mandibular ramus measurements were carried out using Master View 3.0 software. The measurements of the mandibular ramus will be subjected to Discriminant function analysis. Results: Maximum ramus breadth, Minimum ramus breadth, Condylar height, Projective height of ramus Coronoid height were calculated for both the sexes differently with the formula & analyzed with Discriminant function analysis using Fischer exact test. The P value was statistically significant with the P value < 0.05 for the following parameters Max. ramus breadth, Condylar height and Projective height of ramus. Conclusion: Mandibular ramus measurements can be a useful tool for gender determination.
