Cheiloscopy: A tool for antemortem identification

Aims: The present study was conducted with the aim to explore the authenticity and evidentiary value of imprints of the lips for any peculiar pattern regarding specific gender so that it could be used as a reliable tool in the identification of an individual at the crime scene. Materials and Methods: This study comprised 500 (248 females and 252 males) randomly selected dental students with age ranging from 18 to 30 years. Lip prints were recorded with the help of a cellophane tape strip and analyzed according to Suzuki and Tsuchihashi classification. Results: The most predominant pattern in the entire study population was found to be Type I in females and Type III in males with highly significant statistical values. It was also demonstrated that no two lip prints were found to match each other which proves that every individual has unique lip prints. This uniqueness can further help in personal identification. Conclusion: Cheiloscopy or lip print analysis can be used to identify an individual and place him/her at the crime scene. It is an important antemortem tool which may aid in justice to the victim.
