Establishing a person’s identity can be a very difficult process. Dental, fingerprint and DNA comparisons are probably the most common techniques used in this context, allowing fast and secure identification processes. However, since they cannot always be used, sometimes it is necessary to apply different and lesser known techniques. One such technique is cheiloscopy. It is known that due to their special features, lip grooves can be used successfully in human identification. This paper attempts to review the techniques of cheiloscopy, and describes the different classifications and their limitations.
