Online Published on 28 July, 2023. Abstract Introduction Cheiloscopy is the forensic investigation method of utilizing lip prints for personal identification. It has been proved that lip prints are unique for each individual and can be of use in criminal investigation. Latent lip print can be seen on surface such as glass, cigarette butt etc. Many studies have shown a number of ways to develop latent lip prints using fingerprint powder, Sudan III, Oil Red O etc. Aim The present study was conducted to compare the efficacy of three different materials to develop latent lip print - Fullers Earth (Multani Mitti), Indigo and Vermillion (Sindoor) and to see under the stereo microscope. Material and Methods A total of 60 individuals belonging to the age group of 18-34 years were included in this study. Latent lip prints of lower lip were recorded and consequently developed by Indigo blue, Vermillion and Fullers earth. Subsequently a standard lipstick print was taken from the same subject and compared. Subjects having lip deformity, active lesions and surgical scars were excluded from the study. Each sample was assessed and graded according to Renauds classification. Results Lip prints were analysed and compared for efficacy of reagent. Statistical analysis showed significant results between vermillion and indigo blue, and between indigo blue and fuller's earth. However no statistically significant result was observed between indigo blue and fuller’s earth. Top Keywords Cheiloscopy, Latent Lip Prints. Top |
