Cheiloscopy, Identification, Sex DeterminationAbstract
Background: Establishing a person's identity is a mammoth challenge, being confounded by the science of criminology. Dental records, fingerprint and DNA comparisons are probably the some of the most common techniques that are used in this context, allowing fast and reliable identification processes. However, under certain circumstances, they cannot always be used so freely and sometimes it is necessary to apply very less known techniques. In forensic identification, lip print patterns can lead us to important information and help in a person's identification. Objective: This study aims to ascertain the use of lip print patterns in person’s identification and sex differentiation in Odisha population. Materials and Methodology: A total of 140 subjects, 70 males and 70 females were selected from Odisha population. The materials used to record lip prints were lipstick, bond paper, cellophane tape, charcoal powder, an ostrich brush for sprinkling the powder to develop latent print, alginate impression material, cold cure powder and liquid, dental stone to cast lip print and a magnifying lens. Results: Statistical analysis (applying chi square test for proportion) showed significant difference for type I, I', II, III, IV and V lip patterns (P < 0.05) in males and females. Conclusion: This study not only revealed that the lip prints are unique to an individual, but also that they have significant reliability for identification of the sex of an individual.
