Abstract Identification by dental comparison between records of a missing person and the dentition of a deceased individual depends on recognition of concordant features common to both with no unexplained discrepancies. While written dental records are commonly used for this task, we believe they should not be the preferred basis of comparison because they do not derive directly from an individual and are potentially prone to errors, inaccuracies and misinterpretation. Images, however, are a direct representation of a physical item, and are an objective method of recording information. Radiographs are images that capture the unique morphological features of teeth, surrounding structures and physical detail of past dental treatment resulting in changes to a dentition. Taking post-mortem radiographs in such a way as to duplicate as closely as possible the conditions under which the ante-mortem radiographs were produced, permits demonstrably rigorous methods of comparison, raising the probative value of the outcome. In this context post-treatment endodontic radiographs present a particularly rich source of features on which individuation can be achieved, especially considering that alteration of endodontic restorations happens less frequently than is the case with intra-coronal restorations. We illustrate various techniques with a series of cases and discuss the parameters for success.

Scientific study of human skeletal remains with the express purpose of identification. This includes establishing individual identity, trauma analysis, facial reconstruction, photographic superimposition, determination of time interval since death, and crime-scene recovery. Forensic anthropologists do not certify cause of death but provide data to assist in determination of probable cause. This is a branch of the field of physical anthropology and qualified individuals are certified by the American Board of Forensic Anthropology. (From Am J Forensic Med Pathol 1992 Jun;13(2):146)
Disciplines that apply sciences to law. Forensic sciences include a wide range of disciplines, such as FORENSIC TOXICOLOGY; FORENSIC ANTHROPOLOGY; FORENSIC MEDICINE; FORENSIC DENTISTRY; and others.
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.
A technetium imaging agent used in renal scintigraphy, computed tomography, lung ventilation imaging, gastrointestinal scintigraphy, and many other procedures which employ radionuclide imaging agents.
