A Comparative Analysis of Quadrants-Wise Distribution of Lip Print Pattern in Both Genders

Abstract

Lip prints from the crime scene and those collected from suspects may be useful in the determination or narrowing down of the investigation. The present study was undertaken to classify lip prints determine the most common pattern in four quadrants of lip in the study population and evaluate differences in lip prints between males and females thereby investigating their potential role in personal identification. The study was conducted on 200 subjects of which 100 were males and 100 were females. Lip prints were obtained using lipstick and adhesive tape. Our study showed a statistically significant relationship between Type I' lip print in the left lower quadrant and Type I' & Type II lip print in the right lower quadrant with the sex of the individual. Additional research on the lip print pattern is needed to expand the field of forensic anthropology and benefits law enforcement organizations. The variation of the lip print pattern in the four quadrants can aid in personal identification and sex differentiation among populations
