TL;DR: In this paper, the effectiveness of Lysochrome dyes (Sudan III, Oil Red O, and Sudan black) and fluorescent dyes on latent lip prints was compared.
Abstract: Cheiloscopy deals with examination of system of furrows on the red part of human lips and is an important tool in forensic science. The investigation of lip prints (both visible and latent) can thus be fundamental in resolving a criminal act. Traditional lipstick produces a print that is easily identifiable. However, lip prints made without lipstick are invisible, requiring reagents that are more sensitive than conventional materials to locate and develop the prints. This study analyzes and compares the effectiveness of lysochrome dyes (Sudan III, Oil Red O, and Sudan black) and fluorescent dyes on latent lip prints. Keywords: cheiloscopy, latent lip prints, lysochrome dye, fluorescent dye

TL;DR: The vermilion and indigo dye gives comparable results to that of sudan black for developing visible and latent lip prints.
Abstract: Cheiloscopy is the study of lip prints. Lip prints are genotypically determined and are unique, and stable. At the site of crime, lip prints can be either visible or latent. To develop lip prints for study purpose various chemicals such as lysochrome dyes, fluorescent dyes, etc. are available which are very expensive. Vermilion (Sindoor used by married Indian women) and indigo dye (fabric whitener) are readily available, naturally derived, and cost-effective reagents available in India. Objective: To compare the efficacy of sudan black, vermilion, and indigo in developing visible and latent lip prints made on bone china cup, satin fabric, and cotton fabric. Materials and Methods: Out of 45 Volunteers 15 lip prints were made on bone China cup 15 lip prints on Satin fabric and 15 on Cotton fabric. Sudan black, vermilion and indigo were applied on visible and latent lip prints and graded as good (+,+), fair (+), and poor (-) and statistically evaluated. Results: The vermilion and indigo dye gives comparable results to that of sudan black for developing visible and latent lip prints.
