Forensic Evaluation of Dermatoglyphics and Cheiloscopy: Correlation with ABO Blood Types, Gender, and Age

Cheiloscopy, the examination of lip prints and palm prints, has proven to be a useful forensic tool for identifying individuals. This research investigated the forensic reliability of dermatoglyphics and Cheiloscopy through the analysis of the relationship between lip prints, palm prints, thumbprints, gender, age, and ABO blood groups. Conducted as a cross-sectional observational study among 500 individuals aged 18 to 70 at Ranjeet Deshmukh Dental College and Research Centre, Nagpur, the research employed standardized biometric recording techniques. Lip prints were classified using Suzuki and Tsuchihashi’s method, while palm and thumbprints were analysed using forensic classification systems. Statistical analysis, including chi-square tests and Pearson’s correlation, was conducted using SPSS to determine associations. Findings showed lip prints with high correlation with gender, palm prints with correlation to age, and thumbprints with blood groups, proving their forensic application. The research also highlights the need for large population studies and AI-based categorization for precision. In future under resource-poor settings, the data could assist forensic experts in profiling populations and detecting crime. More research would need to focus on multi-regional verification and biometric marker genetics to improve forensic use.
