[The medicolegal identification of victims of major disasters].

The medical identification of victims of major catastrophes is based upon a strict methodological approach at the actual site of the catastrophe when victims are found and in mortuaries. In the majority of cases, police identification can be pronounced. It is only in much more difficult cases where there are calcination or putrefaction processes that medicolegal identification is requested. This identification is based upon the results of medicolegal autopsy itself and on examination of the dental system which remains of capital importance. In the absence of data which can be used to compare the dental system of the victim with this of missing it is possible using single teeth to assess dental age and determine blood group, thereby providing the legal authorities with a group of additional arguments which can be used for presumptive identification.

[Medicolegal identification : teeth and blood groups (author's transl)].

The absorption-elution technique may be used to give adequate grouping in 85% of cases of ABO groups from dental tissue, the results being specific for amounts of 20 to 100 mg of fine powder. ABO antigens are better preserved in the tooth itself, dried, but also to a lesser extent (83% of positive results) in Bouin's fluid whilst formol destroys the ABO antigens of the tooth. Antigenic substances are progressively broken down in relation to the duration and method of preservation. These parameters must therefore be borne in mind for the group O (false "O"). The dental pulp has the same ABO specificities as the tooth and dry or moist preservation better preserves the characteristics. By contrast, areas of caries or damaged teeth result in a high number of errors due to foreign antigens borne by bacteria. With the identification factors which may be provided by study of the odontogram and dental are by Gustafson's method on the one hand, and studies of blood group using powdered tooth or even old dental pulp, the expert may make a medicolegal identification in more than 90% of cases.

[Medicolegal identification by the dental system].

Bodies found in acts of war or natural disasters are sometimes impossible to identify for police or legal purposes, notably because of calcination or putrefaction. Teeth, which are particularly resistant to destruction by fire, bacteria or other agents, can be used to evaluate the victim's dental age by the Gustafson method with a margin of error of plus or minus 4,6 years. Blood group has also been established with more than 85% concordant results by determination of the A. B. O antigens which are present in dental tissue and pulp. These techniques were tested on 257 teeth from subjects of known dental age and blood group. They provide additional evidence of the identity of deceased persons.

[Radiology in the medicolegal identification of cadavers. A new technique of radiography of the maxilla].

After removal, the maxilla and the mandible are placed on a standard radiologic cassette and a X-ray is performed with a low energy beam. Different views can be obtained if required. These radiographic images provide a complete, permanent and detailed record of dental anatomy and restorations, for comparison with antemortem radiographies. Two examples are provided. Moreover, this technique enables the determination of the dental age of children.
