Abstract :

Objective:- The objective of the study was to evaluate the best possible indicator of sex amongst the mandibular ramus measurements (MRM), gonial angle(GA) and position of mental foramen(MF). Aim:- A retrospective study was conducted on orthopantomographs(OPG) of 60 male and 60 female patients, using Kodak 8000C Digital Panoramic and Cephalometric System (73 kVp, 12 mA, 13.9 s). MRM were carried out using Adobe photoshop CS6. The measurements of the MRM , MF index and GA were subjected to discriminant function analysis. Results :- Multiple regression analysis was used to determine the equation for MRM, GA, MF to know the relationship between the independent variable(i.e.Group) among male and females and the dependent variables(Sub Parameters) for MRM. The cut off point for all the three determinants was 0.5, where greater than 0.5 was male and less and 0.5 was female. We found that all the three determinants are a significant predictors in classifying the given sample. Conclusion:- This study on MRM, GA and MF using OPG showed strong evidence suggesting that all the three can be used for wasender determination for forensic analysis. Amongst the three determinants MRM was the most accurate predictor of gender. In MRM, among its dependent variables maximum ramus eadth was considered to be more significant.
