Abstract
Tongue print or lingual impression is a new biometric authentication method used in forensics. Every tongue has its own lingual impression, because of its unique shape and texture. Tongue print is the information carried on the exposed portion of the tongue, that is shape and texture all together. Many studies have been researched into preparing a proper algorithm for tongue image analysis. Digital photographs, lingual moulded impressions, rugoscopy, cheiloscopy, sublingual vein analysis, ultrasound, histological analysis are some of the methods of tongue print collection. Forensic dentistry deals with the proper handling, examination, and evaluation of dental evidence which will be presented in the interest of justice. With the increase in identity fraud and emphasis on security, there is an urgent need to identify humans locally and remotely on a routine basis. Hence newer advancements and research on the potential of tongue prints, as an authenticated forensic tool has to be done.
