Context: With the ever-changing field of criminal justice, the constant revision of criteria for acceptable evidence by the judiciary poses new challenges in forensic investigation. The applicability of cheiloscopy in individual identification is an area of extensive research in recent years. Objectives: The aim of the present study was to determine the distribution of different lip print patterns in North Kerala population, to assess any sexual dimorphism in lip patterns, and to correlate lip print patterns with ABO and Rh blood groups. Materials and Methods: A total of 858 students, 471 males and 387 females, from different colleges in the district of Kozhikode in North Kerala were included in the study. Lip prints were obtained using lipstick and cello tape and transferred onto white papers. Blood group of the participants was noted. Results: The most predominant pattern observed was Type I (48.3%), followed by Type II, Type III, Type IV, Type I', and Type V. We also observed that the lower lip exhibited an overwhelming predominance of Type I pattern in the North Kerala population while the upper lip showed a more even distribution. Gender-wise difference was observed with Type II being the most common in males and Type IV being the predominant pattern in females. No correlation was obtained between the blood groups and lip patterns. Conclusion: The potential usefulness of cheiloscopy in forensic medicine still remains largely untapped and under-recognized. Similar studies in different populations with large sample sizes will allow a more definite picture of lip print patterns to emerge.
