Introduction

It is well-known that dental evidence plays a very important role in the identification of unknown bodies. Of this evidence, X-ray films are considered the most reliable and valid. On the other hand, in recent years, digital X-ray photography techniques have been developed and applied in the field of clinical dentistry. We investigated the application of the direct digital X-ray system to dental personal identification through the use of Compuray (Yoshida Dental Trade Dist., co., Ltd.) (Fig. 1).
