Radiographic evaluation of mandible to predict the gender and age.

Abstract

This study is been conducted using digital panoramic radiographs for predicting age in various age groups and the accuracy of the parameters were accessed as age advances. The selected 300 panoramic images were divided into 3 age group of Group A (25-34 years), Group B (35-44 years), and Group C (45 -54 years). Each group comprised of 100 subjects in which 50 were males & 50 females. The age changes were evaluated using five parameters collectively, which were: Gonial angle, Antegonial angle, Mental foramen, Mandibular canal, Mandibular foramen. These parameters were evaluated on panoramic radiographs for age prediction and changes in their position as age advances. Among all the parameters changes in Mandibular canal and mandibular foramen was found to be highly significant (p value ≤0.05) as age advances. These parameters can be used to predict the age of the individual as there were significant changes in Mandibular canal and Mandibular foramen as age advances. For Further studies large sample size, and recent modalities in radiography like CBCT or CT scan are required.
