A quantitative analysis of subtraction images based on bite-wing radiographs for simulated victim identification in forensic dentistry.

The comparison between ante- and post-mortem radiographs constitutes an important basis for victim identification in forensic dentistry. Due to the decline in dental caries among children that has occurred in Western countries over the last 20 years, the number of restorations in future populations will be limited. It is likely that this will impede successful victim identification in the future. It was the aim of this study to evaluate a new radiographic technique, subtraction radiography based on bitewing radiographs and determine whether it could provide an objective quantitative measure for victim identification. Bite-wings randomly sampled from a large population of adolescents (13-19 yrs) were video-camera-recorded and digitized. Subtraction images were performed of pairs of bite-wings originating from the same individual (identical images) and from different individuals (non-identical images). The images were separated into two groups, one without fillings (12 identical and 48 non-identical) and one with simple amalgam fillings (15 identical and 60 non-identical). The distribution of grey shades in the subtraction image was used as the parameter for evaluation of homogeneity in the images. Subtraction images derived from identical radiographs were significantly more homogeneous than those derived from non-identical radiographs (p < 0.001) in both group with and without fillings. Although the difference was statistically highly significant, the distribution of grey shades in the two groups overlapped. Thus, the grey shades in the subtraction image cannot per se unequivocally establish the identity of a victim, but may add to the subjective comparison of two radiographs in victim identification.

Forensic dentistry in the Cerritos air disaster.

On Aug 31, 1986, 82 people were killed in the worst air disaster in the history of Los Angeles International Airport. The Los Angeles County Forensic Dentistry Team worked with the Medical Examiner-Coroner's Office, the Federal Bureau of Investigation, and other agencies during the identification process. The investigation demonstrated the importance of involving forensic anthropologists and forensic dentists along with investigative agencies in the at-scene search for evidence at disaster sites.

Forensic dentistry.

Data and information derived from the teeth and oral structures have been used successfully where other methods of identification or determination of criminal responsibility have failed. In many instances, the techniques used in forensic dentistry bring evidence to a point of certitude that would otherwise be lacking. Teeth, by their formation and structure and their relative permanence, record and retain the history of their development and the history of the incidents to which they have been subjected. Generally, the characteristics of formation and structure of teeth contribute information pertinent to probabilities of relationships and probabilities of events. As a result, these characteristics are highly useful in affirming or negating evidence as circumstantial or as factual.

Forensic dentistry in a terrorist world.

While body identification by dental means has not changed substantially since 9/11, or even since the bombing of the Murrah Federal Building in Oklahoma City in 1995, the conditions and potential risks of a bioterrorism action to the dental personnel is new. The purpose of this article is to review general forensic dentistry disaster responses and to address the impact a bioterrorism action might have on primary, secondary and tertiary dental responders. It will also examine the triage role that dental offices might play in the event of such a disaster.
