Abstract

Background The cornerstone of an individual's singularity is identification. Digital orthopantomography (OPG) helps to illustrate the varying condylar process, coronoid processes, and sigmoid notch found within a population to facilitate individual recognition. This study aims to assess the various shapes of the condylar process, coronoid process, and sigmoid notch found using OPG in a sample population of an Indian city. Methodology This retrospective, cross-sectional study was conducted using 1,000 good-quality digital OPG scans to evaluate the different shapes. The scans were evaluated by two experienced oral radiologists and tabulated for statistical analysis. Results The current investigation revealed varied morphological forms of the three entities, with the round shape being the most frequently observed condylar process, coronoid process, and sigmoid notch. Comparisons across sides and between sexes revealed differences in all three variables which were found to be statistically significant. We discovered a crooked finger condyle (58.56% on the left side and 41.44% on the right side), a beak-shaped coronoid process (50.0% on the left side and 50.0% on the right side), and a V-shaped sigmoid notch (41.35% on the left side and 58.65% on the right side) in this study. This is a unique finding not reported by other studies. Conclusions Analyzing the shape of the condylar process, coronoid process, and sigmoid notch found on an OPG scan can help with gender identification in forensic odontology and anthropology as these anatomical features show strong sexual dimorphism.
