Blood groups and enzyme types from human teeth.

Paired human teeth and fresh blood samples were analysed for the genetic markers ABO, PGM1, GLO-I, EsD, EAP, AK, ADA, 6-PGD, G-6-PD and CA-II. ABO blood groups were successfully determined from dentine, pulp and cement samples whereas only dental pulp could be typed for different isozymes. Studies on the persistence of these genetic markers in teeth stored at room temperature showed that ABO blood groups were the most stable, followed by PGM1 and ADA isozymes, whereas CA-II isozymes were the least stable.
