Abstract
Background: Research studies and information concern with use of lip prints as evidence in personal identification and crime scene investigation. However, studying in depth, details and establishing further facts and truth in lip prints will definitely help as useful evidence. Identification by any means is a matter of paramount importance in any crime investigation.
Methods: Study was carried out in two districts of Madhya Pradesh these are Ujjain and Jhabua for a period of 02 years. Sample size was 400. A multi stage sampling technique was followed. In this study, we followed the classification of patterns of the lines over the lips proposed by Tsuchihashi, which is the most widely and commonly used classification in literature. It was found to have a clear description of nearly all type of the commonly encountered lip patterns and was easy to interpret.
Results: Type 3 lip print pattern is common in both lip, but more common in lower lip. Type 1B equal (60) in both upper and lower lip, whereas type 4 is (11) in upper lip and (10) in lower lip. Upper lip frequency in tribal and urban group in which type 3 (151) is more common and type 4 (11) is least common. Lower lip frequency in tribal and urban group, type 3(169) is more common and type 4(10) is least common. Lower lip pattern in which type 3 is common and more common in urban (91) as compare to tribal (78). Lip print type 4 Least common in groups, urban (4) and tribal (6). Upper lip print patterns in which type 3 is common similar to lower lip, more common in urban (85) as compare to tribal (66). 1A in tribal group just double to urban.
