Abstract
Background:
Forensic science often uses the skeletal, dental remains as sources for human identification. Sexual dimorphism is the systematic difference in form between males and females of the same species. This study is designed to compute a new formula for sex determination using discriminant function analysis in the deciduous crown dimensions of a paediatric population of Erode district.
Methodology:
The sample consisted of 146 females and 218 males of South Indian origin aged between 3 and 5 years. Alginate impressions of the upper and lower dental arch were made and casts were poured immediately. A digital vernier calliper was used to obtain measurements. Teeth considered for measurement were all deciduous teeth. Statistical analysis was performed using the Statistical Package for the Social Science version 21.0 software (SPSS Inc., Chicago, IL, USA).
Results:
By using the Student t-test, the different predictor variables of teeth selected between male and females were found to be significant (P < 0.05). Significant sexual dimorphism was found in Lower canine Bucco lingual (LCBL), Upper central incisor Bucco lingual (UCIBL), Upper 2nd molar Bucco lingual (UM2BL) and Upper lateral incisor Distal (ULIMD).
Conclusion:
The formula derived from the present study could be of great value in sex determination of paediatric populations of Erode district.
