Cheiloscopy is the analysis of the lip prints, grooves, thicknesses, angles, and other structures of the lips that differentiate each individual in a similar way to biometrics. This study aimed to observe these lips characteristics and to verify if there is a labial pattern among the students of the UFVJM Dentistry course of that distinguishes them in genders. Fifty students were selected, photographed, and had their samples collected by printing their lips on transparent tape with wine 01 lipstick, evenly distributed with the aid of a flexible rod and attached on white paperboard and later classified for obtaining the data required for statistical analysis. When analyzing lip thickness, it was found that most of the students had thick lips - 78%, whereas regarding the position of the labial commissure, 50% of the students presented horizontal disposition. Through the classification system of Suzuki and Tsuchihashi the types of furrows were classified, type II being the most common in this research. Despite the evidence that, among the volunteering students, female lips are thinner than male lips, there were no statistically significant differences between men and women. However, there is a need for more studies that seek to validate and disseminate this technique in a standardized way so that it is a complementary tool in Forensic Dentistry. [ABSTRACT FROM AUTHOR]
