Abstract

Determination of sex of an individual has a crucial role in personal identification. This study aims to determine the sex of an individual from burnt teeth samples exposed to a temperature of 2500C for 15 minutes and 45 minutes respectively through amplification of amelogenin marker. Independent sample t-test analysis of 60 tooth samples revealed that the mean quantity (in ìg/l) and quality of DNA were significantly reduced after heating for 15 minutes (M=9.71, SD=0.45) compared to freshly extracted tooth samples (M=29.91, SD=0.65), t(38)=114.19, p<0.000. The present study is valuable for human identification and the gender identification finally leading to individualization.
