The relationship between calcium and phosphorus concentrations of human saliva and dental plaque

Abstract A direct relationship between inorganic phosphorus concentrations of stimulated parotid saliva and upper posterior plaque was observed in a preliminary investigation with young adults. A similar relationship was demonstrated for inorganic phosphorus concentrations of stimulated mixed saliva and mature plaque in a two-part study with children. A direct relationship between calcium concentrations of saliva and plaque was also observed. The calcium and inorganic phosphorus concentrations of the plaque were directly related to the flow rate of the stimulated mixed saliva.
