Introduction- Sex determination is first step for identification followed by age and stature estimation as both are sex dependent. Mandible becomes important source for sex confirmation in absence of complete pelvis as mandible is considered as most durable facial bone that retains its shape better than others. Panoramic radiography is widely used method for obtaining a comprehensive overview of the maxillofacial complex. Aim and objectives- 1. To evaluate various measurements of mandibular ramus on digital orthopantomographs. 2. To assess the usefulness of mandibular ramus in sex determination. Materials and methods- A retrospective study was conducted using orthopantomograph of 100 subjects (50 males and 50 females). Orthopantomograph were taken by Sirona XP Digital Panoramic Machine (69 kVp 15mA 14.1 sec). The data were analyzed using linear discriminant analysis of the statistical package STATA 13.0. Results- It was found that all variable of mandibular ramus on orthopantomographs was statistically significant p-value <0.01. Conclusion- Mandibular ramus is useful aid for sex determination as it is readily available and resistant to any disintegration process.
Key words- Mandibular ramus, orthopantomograph, linear discriminant analysis
