Study Of Lip Print Pattern Identification On North Indian Population

Abstract

Background: Lip print pattern gives important information which helps Forensic science. The groove or elevation and depression present on human lips (sulci labiorum) are unique to each person and can be used in person’s identification. As in the field of Forensic science fingerprints, postmortem reports, DNA fingerprinting are successfully used in identification. Lip prints also serve as an important role which helps in the identification of those people related to the crime site.  Objective: analyze lip print patterns to identify predominating lip prints and to find out statically significant determine sexual dimorphism on bases of lip print patterns in North Indians.  Material and Methods: study was conducted on 350 subjects (150 male and 200 female) of North India, between the age group of 20 – 40 years. The lip prints of all subjects were taken and had been observed as per Suzuki and Tsuchihashi’s classification from type I to type V and the statistical analysis was done by the chi-square test.  Result: Statistically no significant difference in lip print pattern between male and females (p=0.187*). According to Suzuki and Tsuchihashi’s classification overall distribution of lip print pattern was Type I (26.28%) followed by type III (22.57%), type II (18%), type IV (16.57%), type I’ (8.57%) and type V was (8%).  Conclusion: The study revealed that lip prints are unique for each and every individual. So, it can be concluded that lip prints are unique and may help with personal identification.
