Evaluation of gender determination using lip prints as an adjunctive tool among Indians.

Cheiloscopy is defined as the study of lip prints. Lip prints are permanent and unique to each person and are useful in personal identification. Variations in lip prints patterns among males and females could help in sex determination to throw some light on lip prints and gender determination. The study was conducted on 100 subjects including 50 males and 50 females. Lip prints pattern were recorded and classified as per Tsuchihashi's classification into 6 types. Once the classification was done, then they were compared with each other for determining the uniqueness. The results obtained subjected to the statistical analysis. Majority of the subjects belonged to TYPE 1A and TYPE 1B. Type 1A and Type 1B (32%) was common in females and Type 1A (31%) was more common in males which was statistically significant in determining the gender (p value < 0.05). Lip prints hold the potential to identify gender determination.
