-To estimate the prevalence of lip print pattern, quadrant wise.
-To evaluate the gender differences in the lip print pattern.
It's an observational study, conducted among healthy male and female students of 18 – 25 years of a tertiary care centre in South India. The sample size was 250. Lip prints of the students were taken by four different methods and were analysed with the magnifying hand lens.
The most common type of lip print was Type I, followed by Type III & Type II. On the grounds of gender, Type I was the most common in both Male & Female, followed by Type III. Expression of Type IV & V were more in males whereas expression of Type II was more in females.
A lip print found at the scene of a crime could turn out to be a strong evidence material of the crime. Lip prints, as one of the dermatoglyphics, have been used as genetic markers in many congenital and clinical diseases too.
