This study investigated the feasibility and accuracy of blood types identification through deciduous teeth, using absorption-elution. A total of 15 deciduous teeth extracted from 15 children were used to identify blood types which were compared with the blood types of the children's parents. The blood types of 5 (of 5) samples were fully-identified whose agglutination process took place less than a week. The blood types of four samples (of 5 samples) were identified if the agglutination process took place more than a week. The blood types of two samples (of 5 samples) were identified if the agglutination process took place more than a month. Taken together, our results suggest that deciduous teeth can be used to identify blood types using absorption-elution method for forensic odontology and the accuracy of blood types identification depends on the duration of agglutination.

Key words: Absorption-ellusi, blood type, deciduous teeth, agglutination.
