Human identification in Forensic Odontology mainly involves assessment of dental morphology and their specific traits. Analysis of non-metric traits has been largely studied for sex assessment in Forensic Odontology. However, sexing from metric features of dental remains also facilitates significant aspect. One of the non-metric methods for determining sex includes measuring of different odontometric dimensions such as linear, diagonal and their indexes.
Determination of sex from contemporary extracted molars using dental indexes.
Three dental indexes ⎯ ‘crown/cervical area, ’‘crown/cervical module'and ‘crown/cervical index’⎯ were calculated in a total number of 368 (male and female) extracted permanent molars. Univariate and multivariate (discriminant and regression) analysis were performed using appropriate statistical tools.
All the ratios are statistically significant (p <0.005), as demonstrated by t-test. The general pattern of males having larger values was observed and further the results depict reverse sexual dimorphism. More than 70% of the samples were classified by crown indexes in both discriminant function (stepwise) and regression analysis (forward conditional) to their original sex category.
It was concluded that dental index can aid in narrowing down the data by assigning sex in the forensic scenario.
