Background: Identity are the characteristics including physical, functional, normal or pathological features defining a person. Absence of dry skull or any other part important for identification, mandible plays a predominant role. Mandibular ramus helps in sex determination with the development stages of the mandible, rate of growth, which are definitely different in both sexes. Aim: This study aims to determine the sex using right side of mandibular ramus height. Materials and method: Panoramic radiographs were collected from a database from the forensic odontology department which was later subjected to planmeca and spss for the descriptive analysis. Results: The results obtained for the age group of 21-30 for the females is 66.5600±4.7 and for the males is 78.0300±6.3. For the age group of 31 to 40 for female the mean value is 66.0200±5.6 and for the males the mean value is 76.0200±7.8 For the age group of 41 to 50 for female the value is 68.5500±3.8 and for the male it is 73.4400±4.8 Conclusion: The study concludes that there is no significant relation between sex determination using right side of mandibular ramus height. Males showed greater mean values than the females.
