Cheiloscopy is a branch of forensic science that deals with the study of lip prints or lip impressions. It involves analyzing the unique patterns and characteristics of lip prints to identify individuals, much like fingerprinting.

Cheiloscopy involves analyzing these prints to identify individuals, which is useful in forensic investigations, particularly in cases where fingerprints are not available. The study of lip prints requires a detailed understanding of lip anatomy, including the structure of lip ridges and creases.
