Introduction: Gender estimation is a very important part of a study in the field of anthropology and forensic sciences. In the skeleton, gender estimation is the first step of the identification process as subsequent methods for age and stature estimation are sex-dependent. Skeletal components such as the pelvis and skull are investigated for gender estimation and the mandible is a practical element to analyze sexual dimorphism in fragmented bones. Materials and Method:Study was conducted among fifty males and fifty females using the orthopantomograph between the ages of fifty and sixty.Computational analysis of the obtained data was done using the spss software and results were obtained. Results:The mean Ramus breadth for male is 36.67 ±1.13 , the mean Ramus breadth for female is 36.63±0.85 ,the standard deviation for male is 5.675, the standard deviation for female is 4.274 Conclusion:Mandibular ramus can be considered as a valuable tool in gender estimation and the most reliable measurements were obtained of linear objects in the horizontal plane by digital panoramic imaging but the use of mandible ramus breadth is not reliable.
