Digital Approach For Gender Identification From Lip Print Analysis In Western and Kokan Population of Maharashtra.
Abstract
Background: Cheiloscopy is a forensic investigation technique that deals with identification of humans based on lips traces. Lip prints in each individual is unique like fingerprints. There are many methods for identification of lip prints given in literature. Digital photographs can be used to study the lip prints for gender identification.
Aim: The aim of the study is to identify the predominant lip print pattern in males and females in 18-40 years by using digital photographs.
Material and Methods:
This analytical cross-sectional study included 150 subjects, comprising 75 males and 75 females from age 18-40 years. Digital photographs were used to identify the lip print patterns. The classification given by Suzuki and Tsuchihashi was used to further classify the lip patterns. Kappa test was applied to check for inter observer variation. Statistical analysis was done using SPSS version 23. The association between gender and lip print type was tested by Chi square test.
Results: We have found that Type I was the most common lip print among all participants followed by Type III . Type I’ was the least common lip print followed by Type V in males. Type II was the least common pattern in females .These differences were found to be statistically significant.(p<0.01).
Conclusion: Digital photographs has proved to be useful in terms of accuracy, reproducibility and forensic application.
