Teeth have always been known as stable tissue that can be preserved both physically and chemically for long periods of time. Blood group substances have been known to be present in both the hard and soft tissues of the teeth.
This study aimed at detection of ABO blood group substances from soft and hard tissues of teeth and also to evaluate the reliability of teeth stored for a relatively long period as a source of blood group substances by absorption-elution technique with some modifications.
Blood group obtained from the teeth was compared with those obtained from the blood sample. Pulp showed a very large correlation in both fresh and long-standing teeth though it decreased slightly in the latter. Hard tissue showed a large correlation in both the groups indicating that hard tissue is quite reliable to detect blood group and that there is no much difference in the reliability in both the groups. However, combining pulp and hard tissue, correlation is moderate. Correlation of blood grouping with the age, sex, and jaw distribution was carried out.
Blood group identification from hard and soft tissues of teeth aids in the identification of an individual.
牙齿一直被认为是稳定的组织，在物理和化学方面都能长时间保存。已知血型物质存在于牙齿的硬组织和软组织中。
本研究旨在通过吸收 - 洗脱技术并做一些改进，从牙齿的软硬组织中检测ABO血型物质，并评估储存较长时间的牙齿作为血型物质来源的可靠性。
将从牙齿中获得的血型与从血样中获得的血型进行比较。牙髓在新鲜牙齿和长期保存的牙齿中都显示出非常高的相关性，不过在后者中略有下降。硬组织在两组中都显示出较高的相关性，表明硬组织在检测血型方面相当可靠，且两组的可靠性没有太大差异。然而，将牙髓和硬组织结合起来，相关性为中等。还进行了血型与年龄、性别和颌骨分布的相关性研究。
从牙齿的软硬组织中鉴定血型有助于个体识别。
