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.
