Background: Digital panoramic radiographs can be used as a simple and reliable tool to assess the sexual dimorphism of skull bones for forensic purposes. Aims and Objectives: To compare the measurements of various skeletal landmarks on maxilla and mandible between the genders using digital panoramic radiographs and to evaluate the role of panoramic radiographs in the identification of sex using these landmarks. Materials and Methods: This retrospective study consisted of evaluation of digital panoramic radiographs of 25 male and 25 female patients performed using Planmeca machine and analyzed using DBSWIN software. Various skeletal landmarks were recorded and compared between males and females. Results: Certain variables like height of body of mandible, distance of mental foramen to inferior cortex, inferior cortical width, condylar head width and height, antegonial depth, ramus width and height , articular eminence inclination and height were found to be significantly more in males than females. However, there was no significant difference in variables like gonial angle, fossa depth, maxillary sinus and nasal fossa width. Based on these parameters, a discrimnant functional equation was derived to determine sex. Conclusion: The present study confirms the role of various radiological landmarks on orthopantomograph (OPG) in identification of sex, therefore emphasizing its significance in forensics and research.
