Comparison of Lip Print and Finger Print in Sex Determination of Salem Population

Abstract

Background: In the field of forensic sciences, Practitioners face major problems in personal identification of humans. Lip prints and finger prints can serve as a significant tool for such identification and gender determination as they are unique and distinguishable to each individual. Aim: This study was aimed to evaluate the comparison of lip print and finger print pattern in Salem population for sex determination. Methods: This study comprises 200 lip prints (100 females and 100 males) which were randomly selected among Salem population with age ranging from 15 to 30 years and were collected with lip stick with the help of a cellophane tape on a white sheet, the same people were asked to press the cleaned fingers of right hand over ink-stained pad and the impression of inked finger was then transferred to the same white paper. Lip prints and Finger prints were examined with magnifying hand lens for pattern distribution - classified, recorded and analyzed. Results: Our study proved that the prevalent lip print in the males and females were Type III and type I respectively. The most prevalent finger print in the male was whorls Type and in female it was Loop type. There is statistically significant association between of these two parameters (p value=0.001) and thus these combinations can be implicated in detection of individuals. Conclusion: The use of lip and finger print patterns has been suggested to be consistent and reliable to suspect a fault. Correlation of these two parameters has significant association and thus the result of the present study can provide an additional tool in forensic science for gender determination.
