The presented paper illustrates the significance of dental documentation which played a key role in the process of identification of two unknown male cadavers by means of dental features examination. Efficient operations of the district prosecutor’s office, which in both cases provided ante mortem dental documentation of a missing person likely to be the victim, led to double positive identification. In the first presented case dental examination proved to be more effective than genetics and contributed to closure of the identification procedures. In the second case it confirmed identity equally with genetics. In addition, the paper discusses the basic rules of medical records handling and storage.
