[Enzyme immobilization on the dental enamel and its probable role in the physiology and pathology of the oral cavity].
Immobilized alkaline phosphatase was detected on the dental enamel surface of man by histochemical analysis for the first time. A heretofore unknown mechanism of the regulation of metabolic processes on the enamel-saliva border is discussed. Experimental findings confirm that irreversible absorption represent the immobilization mechanism. A new mechanism of enamel remineralization is suggested: that due to phosphatase-active proteins.
