Age estimation using mandibular ramus and gonial angle using digital orthopantamogram

Abstract

Introduction: Forensic age estimation of unidentified skeletons and corpses for the purpose of identification has been a conventional feature of forensic science. Age determination is of paramount importance in medicolegal issues. Mandible is a dimorphic bone of the skull which aids in determining the age of an individual. Aim and Objectives: This study aimed to assess the efficacy of various mandibular ramus linear measurements (condylar ramus height and coronoid ramus height) and gonial angle measurements on digital panoramic images on the right side of the mandible for age determination. Materials and Methods: Three hundred panoramic images were selected randomly and mandibular ramus linear measurements (condylar ramus height and coronoid ramus height) and gonial angle measurements were performed on the right side, tabulated, and evaluated statistically. Results: Descriptive statistics for all the three parameters on the right side of the mandible were analyzed. No statistical significance was observed between the chronological age and estimated age using the above three parameters on the right side. However, the coronoid ramus height showed a statistically significant result between the chronological age and the estimated age (P < 0.05). Conclusion: In the present study among the three mandibular parameters, coronoid ramus height proved to be a valuable indicator for age estimation.
