Cheiloscopy, the study of lip prints, has emerged as a valuable tool in forensic investigations due to its uniqueness and permanence, similar to fingerprints. This study aimed to analyze the distribution of different lip print patterns among individuals with various ABO and Rh blood groups and assess any potential correlation. A hospital-based cross-sectional study was conducted on 150 participants aged 18–45 years at Meenakshi Ammal Dental College, Chennai. Lip prints were collected using cellophane tape and classified based on Tsuchihashi’s system. Blood group analysis was performed, and statistical analysis was conducted using the Chi-square test. The results revealed that the most common blood group was O+ (38%), followed by B+ (29.3%) and A+ (18.6%). The most prevalent lip print pattern was Type I (Vertical, 31.3%), followed by Type II (Branched, 26%), and Type IV (Reticular, 16.7%). Statistical analysis showed no significant correlation between lip print patterns and ABO blood groups (p = 0.145). Additionally, no significant difference was observed in lip print distribution between males and females (p = 0.629). These findings align with previous studies, suggesting that lip prints and blood groups are independent traits. While lip prints remain a valuable forensic tool for personal identification, their correlation with blood groups lacks statistical significance. Further research with larger sample sizes and genetic analysis is recommended to explore potential biological links.
