ABSTRACT

Aim To analyse the various morophological variations of the coronoid process and to determine the mandibular angle using digital orthopantamograms (OPGs) radiographs in a retrospective analysis for identification of the sex of the individual. Material and methods The study was carried out using 50 digital OPGs comprising of both sexes and the different shapes of the coronoid process were traced and the mandibular angles were measured bilaterally. Results The most commonly observed outline form of the coronoid processes were triangular in males whereas round in case of females. The average mandibular angle measurement was found to be 99.8 degrees in males, whereas was found to be a little more increased in females i.e. 105.3 degrees in females. Conclusion Although there were variations even between both the right and left coronoid processes of the individual with varied shapes such as round, triangular, flat and beak like, the majority and most commonly occurring outline form of the coronoid process can be used tentatively for identification of the sex of the individual. Similarly there variations in the measurements of the angle of the mandible, still the average measurements revealed a more obtuse inclination for females compared to males which suggest that with these parameters the gender can be determined to a certain extent and can also be used in forensic analysis.
