ABSTRACT There are various methods for the identification of human remains; most of them are based on comparisons between available ante- and post-mortem data. Although fingerprinting is the most accurate and precise method, in many cases, such as in mutilated, decomposed, burned or fragmented bodies, it cannot be used, and the dental methods become of the utmost importance, since teeth and dental restorations are very resistant to destruction by fire--they keep numerous characteristics, which are quite unique, and offer the possibility of accurate and legally acceptable identification of remains. This brief review describes the progress of forensic dentistry during the last 25 years, regarding the procedures and techniques that use ante-mortem and post-mortem radiographs. Among the discussed progresses one can point out: a specially designed self-supporting film holder that retains intra-oral films in the mouths of deceased persons whose mandibular musculature has been fixed in rigor mortis; positioning devices suitable for reproducing the geometry of ante-mortem radiographic images; methods involving digital radiographs, which can be easily stored in a central archive, retrieved and transmitted, via modem, to mass casualty sites; age estimation procedures; identification of edentulous individuals comparing radiographs of the maxilla; and studies of validation of dental radiographs taken with ante-mortem and post-mortem intervals of up to 30 years.

    ABSTRACT: Fingerprinting is the most widely accepted method of identification of people. But in cases of disfigured, decomposed, burnt or fragmented bodies, it is of limited value. Teeth and dental restorations on the other hand are extremely resistant to destruction by fire. They retain a number of their original characteristics, which are often unique and hence offer a possibility of rather accurate and legally acceptable identification of such remains. This study was undertaken to evaluate the utility of orthopantomography for human identification and propose a coding system for orthopantomogram (OPG), which can be utilized as an identification tool in forensic sciences.

    ABSTRACT: Age estimation is one of the primary demographic features used in the identification of juvenile remains. Determining the accuracy and repeatability of age estimations based on postmortem computed tomography (PMCT) data compared with those using conventional orthopantomography (OPT) images is important to validate the use of PMCT as a single imaging technique in forensic and disaster victim identification (DVI). In this study, 19 juvenile mandibles and maxilla of known age underwent both OPT and PMCT. Three raters then estimated dental age using the resulting images and 3D reconstructions. This assessment showed excellent agreement between the age estimations using the two techniques for all three observers. PMCT also offers a greater range of measurements for both the dentition and the whole human skeleton using a single image acquisition and therefore has the potential to improve both the speed and accuracy of age estimation.
