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.
吸收 - 洗脱技术可用于对85%的来自牙齿组织的ABO血型进行适当分型，对于20至100毫克细粉量的结果具有特异性。ABO抗原在干燥的牙齿本身中保存得更好，但在Bouin液中也能在较小程度上保存（阳性结果的83%），而甲醛会破坏牙齿的ABO抗原。抗原物质会随着保存时间和方法而逐渐分解。因此，对于O型血（假“O”）必须牢记这些参数。牙髓与牙齿具有相同的ABO特异性，干燥或湿润保存能更好地保留其特征。相比之下，龋齿或受损牙齿区域由于细菌携带的外来抗原会导致大量错误。一方面通过研究牙片和采用古斯塔夫森方法对牙齿进行研究可提供识别因素，另一方面通过使用粉末状牙齿甚至陈旧牙髓进行血型研究，专家在90%以上的案例中都可以进行法医学鉴定。
