Relation of salivary phosphorus and alkaline phosphatase to the incidence of dental caries in children.

The phosphorus concentration and alkaline phosphatase activity in saliva may be related to the susceptibility to dental caries and supragingival calculus. Hence, the unstimulated mixed saliva of child patients were assayed by biochemical methods to determine the phosphorus concentration and alkaline phosphatase activity in such salivary samples. It is very interesting to note that higher phosphorus concentration and alkaline phosphatase activity were found in patients with rampant caries as compared to that with non rampant/control group.
