A Comparative Study On Cisgender And Transgender Individuals With Cheiloscopy

Abstract

INTRODUCTION: Lip print evaluation, or cheiloscopy, is growing in popularity in forensic science to recognize individuals. This study bridges the gaps in prior studies by employing transgender data and quadrant analysis, providing thorough insights into the use of cheiloscopy for forensic identification. Conclusions show the significance of regional and gender-based differences while illustrating the consistency of dominating lip print patterns across populations.
AIM & OBJECTIVES: To study the morphological pattern and classification of lip prints among males, females, and transgender individuals. 1. To compare lip prints of males, females, and transgender individuals. 2. To classify the obtained lip prints according to Suzuki’s classification. 3. To identify which type is more predominant in males, females, and transgender individuals.
CONCLUSION: In this study, the findings of earlier research investigations correlate with cheiloscopic patterns seen in a modern population sample. According to the current study, Type I (54.3%) and Type II (37.7%) are more common in females, but Type II (45%) and Type III (42.3%) are more common in males. Additionally, Type II was the most common pattern (16.6%) determined by transgender data, which was excluded in previous studies. While Type I is common in females, with some regional differences, Type II and Type III are similarly dominant in males, based on an unbiased review of previous research. In addition, Type V is consistently rarely seen across all categories, as determined by the study. The current study's forensic relevance is increased using quadrant-wise analysis, which offers an extensive understanding of lip print dispersion patterns.
