Gender Dimorphism of Permanent Maxillary First Molar – A Forensic Radiographic Study

Aims and objectives: Identification of an individual is based on characteristics like gender, age and racial background unique to that individual. Out of all the parameters determination of gender falls first in line. Teeth can be used to determine gender dimorphism as they are the hardest structures and can withstand any adverse conditions. The present study aims to determine gender of an individual based on the mesio-distal (MD) dimensions of permanent maxillary first molar teeth from a panoramic radiograph and analyse sexual dimorphism exhibited by the tooth. Materials And Methods:MD width of 100 permanent maxillary first molar teeth were measured from panoramic radiograph of 50 male and 50 female patients between the age group of 1840 years. Statistical analysis was performed using SPSS 22. Results: Results showed no statistical significance in the MD width of permanent maxillary first molar between males and females. In conclusion MD width of maxillary molars measured from panoramic radiograph have been found not to demonstrate significant sexual dimorphism.
