In this study, we aimed to investigate the sex-discriminating potential of mandible dimensions, which we hypothesise can be measured easily and can indicate various sex discriminant functions in a simple manner. Statistical analysis was performed using data from five linear measurements and 10 indexes acquired from 14 landmark coordinates on 240 three-dimensional Korean mandible models (120 male and 120 female). The Korean mandible showed sex dimorphism in all the measurements and in four indexes (p<0.01). Discriminant functions were generated by univariate, bivariate, and multivariate analyses using direct and stepwise methods, with accuracy ranging from 51.3% to 89.6%. Moreover, when comparing the dimensions of Korean mandibles with other populations, morphological differences were observed, thus implying that the sex discriminant functions can be generated according to each population. Therefore, in the present study, we noted that the various discriminant functions assessed using three-dimensional models of the mandible in this study indicated that the mandible dimensions alone had sex-discriminant potential, and our findings thus provided useful information for forensic examiners to accurately predict sex in a Korean population.
