[Systematic aspects of roentgen identification--practical methods and new aids].
Radiology plays an important role in the identification of unknown corpses. Positive radiographic identification by comparison with ante-mortem films is an established technique in this setting. The value of identification depends on the ante- and post-mortem processing parameters which should be equal. A film-holder which is normally used in clinical dentistry has been modified for forensic investigation. The difficulties in placing and retaining intra-oral films in the mouths of deceased persons are minimised by the use of this holder. New equipment for film marking is described and different exposition times recording to the thickness of covering soft tissues were developed. Mistakes in the developing process are discussed. A forensic case underlines the advantages of systematic investigation.
