Lip Prints and Gender Identification

Abstract

Lip prints are wrinkles and grooves present in the transition zone of human lip. The study of lip print is referred to as cheiloscopy and it is unique to every individual. They do not change during their entire life. The purpose of this study is to find out most common lip print pattern and to assess their efficacy in sex determination. In this study, each individual had unique lip print pattern. Type I (vertical) was the predominant pattern in both males and females. There is statistically significant difference between gender and type of upper lip print pattern, but there is no correlation regarding lower lip pattern contradictory to many earlier studies. Hence, lip prints can be used as tool for identification of an individual and gender identification.

Forensic Correlation of Lip Prints Patterns and Sex Determination Among Adult Egyptians: Lip Print Versus Lip Dimension

This sexual difference was partially approved in only patterns of upper lips by(Raj et al, 2016) in their work for the Indian population.In contrast, the gender difference correlation was not possible by Shokry et al, 2017, although their work included an Egyptian sample, they used different print classification (Renaud Classification) and different lip areas (they divided the print into 6 partitions including the margins which may be narrow and non-obvious). Numerous studies approved lip prints' sexual, discriminatory value for the Indian population as seen in Table (6).…”
