📝 Abstract
Background: Forensic science uses both lip prints and palm prints for personal identification, as these are unique and do not change in the lifetime of the individual. Although not uptoparwith fingerprints, palm prints and primary lines in both hands may be helpful when prints areinsufficient for gender dimorphism.
Aim: To analyse the predominant pattern of lip prints and palmprints and to identifythecorrelation between right and left palm print patterns and lip print patterns in females andmales.
Materials and Methods: The study involved 100 participants, with 50 males and50females, whose lip and palm print patterns were collected. Lip prints were taken by applyinglipstick and pressing the lips against paper, following the Suzuki and Tsuchihashi classification. Palm prints were taken using a digital camera, focusing on the primarylinesofthe thenar, hypothenar regions, and proximal triradius of the second and fifth digits, basedonthe Wu et al. classification.
Results: The study reported 82% Type I' in females, 76% of males in Type I, themost frequent patterns were Type I' for females and Type I for males. Lip print pattern was not correlated significantly with the right and left palm print patterns for either gender sincep-values for both males and females were greater than 0.05.
Conclusion: The use of standard lipsticks for collecting lip print impressions is themost convenient and easiest method. The Chi square test is also the most reliable test for gettingthe best outcomes in the analysis of palm prints. Personal identification was aidedbythesignificant gender dimorphism and the correlation between palm patterns of females andmales that were noted.
