Cheiloscopy is a forensic investigation technique that deals with identification of humans based on lips traces. The aim of this study was to establish the uniqueness of lip prints and to look out for any new character which aids in personal identification. In the study, we followed the classification of patterns of the lines on the lips proposed by Jerzy Kasprzak in 1990. In the present study we collect the lip prints of 50 females of 18-25 years of age (having full dentition) were collected the lip prints were then studied for the pattern and characteristic features present at its quadrant for analyzing variations, and to determine the most common pattern in the study population. The statistical calculation after study estimated that Simple Bifurcation is more prominent in upper lip with 56% and Simple Bottom Bifurcation is prominent in lower lip with 68%. However calculation shows that A Line Like (I) feature is most common, when both upper and lower lips are taken into consideration with 44% presence. On extensive of lip prints samples,
a new character “A Bar” denoted as “x” in the script was found in both upper and lower lip with a requency of 14% and 16% respectively. The present study is an attempt to propose a better method of personal identification based on lip prints for forensic investigation.
