Abstract

Biometric is a real time identification system using physical characteristics. The tongue can be used as a novel identification system and a potential forensic tool. Tongue prints can be captured either by clicking a photograph of the dorsum of the tongue or by obtaining an alginate impression. Tongue printing dates back to the era of traditional Chinese medicine. Tongue prints and their interpretation is also important in diagnosing cases of HIV, upper gastrointestinal problems, etc. Multiple studies have been performed to establish a universal classification of tongue prints. Still, there is a lack of availability of data about the population of different geographical locations. Hence, it also opens up new research avenues for upcoming researchers. Keywords: Tongue prints, biometric, identification, forensic odontology, tool. Key Messages: Tongue prints can be used as a reliable new technique for biometrics assessment because of their genetic independence, stability over time, and physical protection from the external environment. Hence, it also opens up new research avenues for upcoming researchers.
