Human identification is a universal process of certification of death and for personal, social and legal reasons. Lip prints are unique and do not change during the life of a person. So it can be taken as one of the person identification tool. The present study was aimed to find out whether there are any peculiar / common lip patterns found among males and females and to determine the frequency and repetition of different lip patterns in each quadrant of lip among the same subject. The present study was conducted among 210 subjects, aged 5-70 years. The lip-imprints were taken by researcher 1 and analysis of different lip patterns was performed by researcher 2. Results showed that 91.4% males and 89.4% females were positively identified. It has been found that Type I, I-, II patterns were most commonly found in females, while Type III and Type IV lip patterns in males. As per the quadrant wise analysis the most frequent lip pattern in males and females in upper right quadrant was Type III (53.3%) andType II (52.2%), in upper left quadrant Type III (65.7%) and Type II (44.8%), in lower right quadrant Type IV (47.6%) and Type II (45.7%) and in lower left quadrant it was Type III (65.7%) and Type I (33.3%) respectively. The study concludes that, quadrant wise determination of the lip patterns may aid in confirmation of the sex of an individual.
