Comparative study of cheiloscopic patterns among Indian and Iranian dental students

Aim and Objectives: To assess and establish the cheiloscopic patterns in Indian and Iranian dental students between the both genders and compare both the groups. Materials and Methods: The study sample consisted of 80 students in the age group of 20‐30 years. Lipstick, brush, white paper, adhesive cellophane tape, and magnifying glass were used for the study. Adhesive cellophane tape was used to take the lip print of each individual without any distortion. After carefully removing the cellophane tape, it was stuck onto a white paper. The impression of the lip was splitted into four segments and it was examined using a glass which can magnify the size of the object which is viewed. Lip imprint impression patterns were segregated using classification given by Tsuchihashi and Suzuki. Results: Indian and Iranian dental students showed differences in patterns of lip imprints which is of statistical significance. Conclusion: Lip imprints are specific to a person and unchangeable like fingerprints, so it can be regarded as an important aid in forensic investigations.
