Abstract
Zmale and females (p > 0.05). There was a significant difference in the GP and OP of
first premolar (PM1) and second premolar (PM2) between male and female (p < 0.05).
However, there was no significant difference in the GP and OP of first molar (M1)
between male and female (p > 0.05). Sex classification accuracy was 62.7% for the
CN, GP, and OP of maxillary posterior teeth. The GP showed 100% uniqueness for
PM1, PM2, and M1. The OT topography showed 100% uniqueness for PM1, PM2,
and M1. Similarly, the OT showed statistically significant difference (p<0.01) between
the root mean square (RMS) values of the matched and non-matched pairs. In
conclusion, the maxillary posterior teeth in Malay population showed significant
sexual dimorphism and sex determination potential. The GP and OT of maxillary
posterior teeth show 100% uniqueness that indicated both parameters are useful for
human identification.
