Ph.No.9980902559 E-Mail: drvara.hitesh@gmail.com Background: The challenges faced by man in early days to provide the identity of an individual. Identity means determination of distinctiveness of a person, which is very important in legal medicine and criminal investigation. Cheiloscopy is a forensic investigation that deals with the identification based on lip traces. The lip prints are individualistic like the finger prints and do not undergo alteration during the life of an individual. The aim of the present study to assess the lip print pattern of different individual in different quadrant of lip and to evaluate the lip prints for their uniqueness. Materials and method:The study was conducted on 100 medical students (50male and 50 females) of 18-23 years from A.J.Institute of Medical Sciences, Mangalore. Lip stick was applied on the lips and print was taken with the help of white bond paper. While studying the lip print 4 quadrants were made on the lips as upper right and upper left and lower right and lower left. Predominant pattern in each quadrant is obtained by using Suzuki’s classification and result s are analyzed statistically by calculating the percentage for each pattern in each quadrant of lip. Result: The present study showed type 1(vertical) was the overall most common pattern among both male and females.In males, 40% were having type1(vertical), 26.5% of type3(branched), 13.5% of type2(partial length), 12% of type 5(intersected) and 8% of type4 (reticular). In females, 37.5% were having type1(vertical), 22.5% of type2(partial length), 22% of type3(branched), 11% of type 4 (reticular),and 7% of type 5(intersected). Conclusion: Study revealed that the lip prints pattern for each individual in each quadrant is unique. Lip print patterns are constant do not change with time.Because of its uniqueness and constant nature it can be used in the personal identification mainly for criminal and legal investigations.
