Human identification is required chiefly for legal reasons. It is also required on humanitarian basis also. The primary step in any identification process is determination of the sex, which forms the basis of other subsequent methods for age and stature estimation. Mandible may play a key role in sex determination as it is the most dimorphic, largest and strongest bone of the skull. Dimorphism in mandible is with respect to size and shape and are usually larger and stronger in males than in females. Some studies were conducted on behalf of the mental foramen in sex determination. The need of the hour was to design the present study to determine sex using seven variables on mandibular ramus, intercondylar distance and position of mental foramen in South Indian population. Aim was to measure, compare, and evaluate the various measurements of the mandibular ramus, position of mental foramen and intercondylar distance for sexual dimorphism in digital OPGs. The digital panoramic radiographs of 300 subjects aged 20-60 years based on inclusion and exclusion criteria were used for the study. Statistical analysis was done using SPSS. Results showed that 10 out of 14 variables measured in this study showed statistically significant (P < 0.05) differences in gender.

So it can be concluded that the above used landmarks can be used for sex determination either on dry mandible or through OPG.
