BLOOD-GROUPS AND ENZYME TYPES FROM HUMAN TEETH

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