Utilisation of non-dental radiographs in forensic dental identification of unknown human remains: a Queensland case series

Abstract

Forensic odontology is one of INTERPOL's three primary identifiers for Disaster Victim Identification (DVI). Forensic dental identification relies on the availability of antemortem dental radiographs, such as orthopantomogram (OPG), dental cone beam computed tomography (CBCT) scanned images, bitewing, and periapical (PA) views. These antemortem dental radiographs are used for comparison with postmortem dental radiographs. However, there are other types of non-dental medical radiographs that also capture dental structures. These medical radiographs are proven to be useful in forensic dental identification. This Queensland case series highlights the importance of non-dental radiographic images for the purpose of forensic dental comparison including the first published forensic dental identification involving comparison of a postmortem computer tomography (PMCT) multiplanar reformat (MPR) image with non-dental antemortem radiography. This case series also highlights the benefits of a collaborative working relationship between the forensic odontologist, forensic pathologist, police, and Coroner, in antemortem data collection.
