Abstract: In major disasters like air-plane crash, bomb-blast, fire accident and flood, the biometric means like finger print, retina, hand print, palm print, face details etc., may not be available. Hence in such a circumstance there is a need for another reliable, unique and useful means like tooth to develop an automated dental identification system. For dental biometric system the ante-mortem records has to be matched against the post mortem records. In the dental identification system, missing tooth detection and teeth numbering are few of the notable issues. This paper addresses these issues with the help of spline function, bifurcation techniques and template matching approaches. This review focuses these issues both for radiographic and photographic dental images since adequate radiographic records may not be available in almost all the instances. Experimental evaluation shows satisfied results which will abet the dental biometrics.
