Dental biometrics is the leading biometric technique to identify individuals on the basis of their dental characteristics. Dental Features of persons are naturally unique, one of feature include jaws of a person maxillary jaw (upper jaw) and mandible (lower jaw). Here, most of the similarities are matched so that human being can be exactly identified by its unique feature i.e. maxillary jaw. We will use efficient workable method to authenticate humans correctly and identify them properly, which is based on dental work information extracted out from dental data. This paper is all about a proposed method where it includes some major processing stages that consist of preprocessing, feature extraction, classification etc. This whole part will be implemented in matlab software for easy identification. Matlab software contains a powerful tool to employ all processing stages. Key Words: Dental biometric, maxillary jaw, mandible. 1.INTRODUCTION The field of biometrics has got so much importance from few years because it is an interesting and a different way to identify humans than that of traditional authentication systems previously developed like passwords. Under various circumstances e.g. disasters conventional biometric characteristics like fingerprints etc, may not be able to work because of their incompatibility in such cases .In this case, dental features are considered a useful tool for of human identification. In order to achieve our desired mentioned goal, dental biometrics automatically analyzes dental radiographs, stored in a database through some described processing. In addition to this, forensic human identification is crucial and a big issue world- wide. At present security conditions, biometric identification is the most promising way to authentic humans with highest accuracy rate. A lot of research has been done in the field of different biometric modalities like Finger-print, Iris, Hand-Veins etc to identify humans. Within these various modalities, Dental Biometric has leading edge over others. Because of reason a lot of dental biometric characteristics have been associated with maxillary bone. Other modalities e.g. finger print, palm print; they have more complex features in it. They might leads sometimes towards high error rate. And also, there analysis is more complex. Thus dental biometrics gets priority over other in considering features and analysis point of view. Approaching in a different Way, the system of dental biometrics has not as developed as some other modalities. In this sense, it is being an intelligent approach to explore the new fields of research. Human identification has been done in various modalities like finger print, ear, face, hand vein recognition. Various strategies have been proposed and a lot of advancement is required also. The maxillary jaw is a name for the upper jaw, and it includes several bones stuck (or fused) together, and it is in front of and just below the cranium. Also attached to the cranium and form the cheek, the nose, and the roof of the mouth. The air filled space known as maxillary antrum or sinus that sits just under the cheekbone, and just above the roof of the mouth.There is one on each side of the face, either side of the nose. The anterior nasal spine is a bit of bone which protrudes from the maxilla at the lower end of the nose. The zygomatic process is a curved
