title: Changes of phosphomonoesterase activity in human dentine during the formation of the root of the tooth.
abstract: The changes of acid and alkaline phosphatase activities were quantitatively analyzed in different layers of dentine in developing and intact states of human teeth. The peripulpal areas revealed the highest activities. In the mineralizing apical area the alkaline phosphatase activity was ten times higher than that in fully-formed teeth.
