When fingerprint, DNA and post-mortem records are not available, lesser known techniques of palatoscopy and Cheiloscopy can throw light on individual identification. The present study was conducted to compare the Lip prints between the Tibetan population from Mundgod and the population of Belgaum and to find out the quadrant wise and gender-wise predilection of lip print patterns.
Lip impressions were collected from 775 Tibetans from Mundgod and 764 subjects from the population of Belgaum city. A dark shaded lip stick was applied on the lips of the subjects and the impressions were taken on the sticking side of a cellophane tape and stuck on a white paper. The impressions were visualized using a magnifying lens and analyzed by Suzuki's classification.
The data was entered in Microsoft excel and analyzed using Chi square test. The Type I pattern was more common in males in the first and second quadrants. Type II pattern was more in the Tibetans than in the general population. Type III pattern was more common in males. It was seen more commonly in the Tibetans. Type IV pattern occurred more frequently in females in both the populations. The variability in occurrence of different types of lip prints in both the populations was statistically significant. Lip size of the Tibetans was larger than their counterparts from the general population.
Lip prints have a gender-wise as well as quadrant-wise predilection. The two races compared in this study were found to have differences in the distribution of lip prints.
