Prediction of Sex from Teeth Linear Dimensions and Indices

Determination of sex is one of the most important and vital steps in forensic medicine. Sexual dimorphism using odontometric analysis is found to vary in different populations making it necessary to attain values of a specific population which makes identification of person as easy as possible. The present study aims to establish sexual differentiation using dental parameters including dental linear dimensions and indices. Maxillary jaw casts from total of 100 subjects (50 males and 50 females) between ages 17 and 24 years were taken. Mesiodistal (MD) and Buccolingual (BL) dimensions of each tooth of from maxillary jaw cast excluding third molar were measured using precision calipers, dental indices were calculated. Data was collected and statistical analysis was done using SPSS software version 20. Bucccolingual dimension was proved to be a better parameter than MD for assessment of gender in case of left central incisor, canines and left first molar. Crown index of right central incisor, second premolars, and left first molars was the best index for sex prediction of most of the teeth.
