    Abstract

    Fingerprints are commonly used for identification 1. All records are computerized. In a catastrophe recorded images of soft tissue may become useless if the tissues burn throughout.

    Dental prints are rarely used for identification. Information is taken from dental radiographs or dental casts. In case of fire recorded images of dental structures may be useful because they do not readily burn.

    Introduction

    Introduction

    Fingerprints are commonly used for identification 1. All records are computerized. In a catastrophe recorded images of soft tissue may become useless if the tissues burn throughout.

    Dental prints are rarely used for identification. Information is taken from dental radiographs or dental casts. In case of fire recorded images of dental structures may be useful because they do not readily burn.

    Discussion

    Discussion

    Dental occlusal contact occurs with the matching of one jaw to another in a closed position. Occlusal contact prints are located between the opposing maxillary and mandibular dental arches when closed. The resulting image is a composite of the occlusal contact areas of the opposing jaws and the surrounding dentitions. Impression making like fingerprinting must be done by a professional and the results must be analyzed by a professional. Dental impressions are taken in a dental clinic. Dental personnel can be trained to make suitable impressions and to store the data. As with fingerprinting impression making must be precise. 7 An investigator can identify jaw and tooth contours without analyzing tooth contacts. A dentist can identify tooth contacts and tooth rubbings by interpreting occlusal surfaces which represent occlusal contact and grinding areas. No two occlusal contacts or dental articulations are alike. Dental impression systems for identification employ thermoplastic materials and are used for children 89. The plastic impression is stored in a small box. The new instant impression system is primarily used for adults. The results are photographed and made internet available. The impression is discarded.
