Lip prints are lines, also known as grooves and fissures, on the skin that form at the junction of the labial mucosa and the lip's exterior surface. The study of these lip prints is known as chelioscopy. They are known to follow a pattern, which has been classified into multiple categories by various experts. Suzuki & Tsuchihashi's classification proved to be the most popular. They are also noted for having a few distinguishing characteristics that aid in determining a person's personality. The current study was conducted to examine quadrant-wise patterns and differences between males and females. In our study, the most prevalent lip print in males was type I (32.91%), followed by type 3 (22.50%). In females, type 1 was the most common (39.16%), followed by type 3 (20%). Study found significant variations between males and females in lower lip print patterns.
