Background: Indubitably, lip prints are one of the most core findings in a forensic study. Since the prints are exclusive to each discrete humanoid, they serve as the preliminary tool for identification of individuals. The prints remain non-distorted by any external factor inclusive of variations in environment, the prevalence of oral diseases or any form of external trauma. The core aim of the article was to establish different types of lip prints based on the age group and gender of the individual. Materials and Methods: As part of the study about 380 adults in the age group of 18 years to 35 years were subject to participation. Both males and females were involved in the study and lip prints were documented and evaluated for varied lip patterns. The materials utilized for the study comprised of a dark purple lipstick, highly durable paper, scotch tape, brush, and a high power magnifying glass lens. Results: The prevalence of the Type Ia pattern was observed among 31.05% of males and 33.68% of females. The occurrence of the Type Ib pattern was observed among 16.31% of males and 17.36% of females. The incidence of the Type II pattern was pragmatic among 24.21% of males and 20.52% of females. The type III pattern was perceived among 10.52% of males and 13.68% of the females. The type IV pattern was observed among 10.00% of the males and 8.42% of the females. The type V pattern was observed among the 7.89% of the males and 6.31% of the females. Conclusion: Even though there is a similarity in the type of lip pattern for each person, the lip prints are exclusive for every humanoid. Clearly, as a part of our study, the uniqueness of lip prints have been established. Furthermore, we discovered that Type I was the leading pattern in both the sexes and the Type V was the least prevalent pattern in both the sexes. The criminality enforcement agencies must deliberate lip print analysis as an imperative tool in human identification.
