A Review of Dental Biometrics from Teeth Feature Extraction and Matching Techniques

Dr. Ganesh Sable | Dipali Rindhe

Abstract: Biometric is a tool of identification that has been broadly used in many applications. A biometric identification system is based on physical characteristic. Dental biometrics has emerged as vital biometric information of human being on account of its stability, invariant nature and uniqueness. It utilizes dental photograph and dental radiograph for human identification because it provides information about teeth including tooth contour, relative position of neighboring teeth and shapes of dental work like crown, fillings and bridges. A biometric identification system is based on physical characteristics such as face, fingerprint, palmprint, fingerprint, eyes (iris, retina) and DNA. However, many of those characteristics are only suitable for ante mortem identification when a person to be identified is still alive. They cannot be used for post mortem identification specially in such cases of decay or severe body damage caused by fire or collision, due to this dental biometrics plays an important role in human identification and post mortem identification. This paper address review of such different techniques used in dental biometrics
