Dental identification of unknown bodies through antemortem data taken by non-dental X-rays. Case reports.

Abstract

The dental radiographic comparison is one of the most reliable and scientifically accepted methods for body identification (ID). The heterogeneity between AM (ante mortem) and PM (postmortem) x-rays images continues to stand as an issue for the forensic odontologist. Casual dental findings on X-rays for investigation of other structures than teeth or maxillaries, could eventually be a relevant source of dental data for the ID especially when AM dental files or X-rays are lacking. Two cases are reported in which the body ID was achieved through the comparison of PM dental X-rays with dental images obtained by radiographies of other structures (e.g. X-rays of the skull or cervical spine). These cases highlight that these occasional dental findings might provide sufficient evidence for a body identification. In the collection of AM data of missing people, the collection of all available records and radiographies of the head, neck and chest should be carefully reviewed by forensic odontologists, seeking for any available dental data.
