Study for Determination of Sex Using Mental Foramen: An Institutional Based Study
Keywords:Mental Foramen, Sexual Dimorphism, Panoramic Radiographs, Forensic
Background: Identification of human skeletal remains is an important part of forensic analysis. In adult skeleton, sex determination is the first step, followed by age and stature as age and stature are sex dependent. The present study was conducted to determine sex using mental foramen.
Materials and Methods: A present study was conducted to determine sex using mental foramen. A total of 70 panoramic radiographs were examined and selected retrospectively. 140 mental foramina were analyzed for the study. 140 mental foramina were located in the panoramic radiographs and traced. The measured distances were tabulated and analyzed. Statistical analysis of the data was done using SPSS Version 20.0 (SPSS Inc., Chicago, Illinois, USA). Results: In the present study a total of 70 consisted of 35 males and 35 females panoramic radiographs were examined and selected retrospectively. Superior tangent to the Lower border of the mandible (SL) was measured. The mean and standard deviation in males was18.21±3.12mm on the right side and 18.10±3.45mm on the left side. The mean and the standard deviation in females was14.32±2.01mm on the right side and 15.02±2.11mm on the left side. Inferior tangent to the Lower border of the mandible (IL) was also measured. The mean and standard deviation in males was 14.91±2.98mm on the right side and 14.54±3.25mm on the left side. The mean and the standard deviation in females was 12.24±1.45mm on the right side and 12.65±1.64mm on the left side. Conclusion: The present study concluded that mean values of SL and IL were significantly higher in males when compared to females. There was no significant difference between the measurements of right and left sides of both males and females. Therefore, mental foramen can be used as a marker for sexual dimorphism.
