Saturation of human saliva with calcium phosphates

Abstract

Salivary saturation was calculated in respect to hydroxyapatite (HA), tricalcium phosphate (TCP), octocalcium phosphate (OCP) and dicalcium phosphate dihydrate (DCPD). The calculations were based on ionized calcium and ionized orthophosphate in resting parotid saliva and in stimulated parotid submaxillary and whole saliva. The findings snowed that samples of resting parotid saliva were least saturated and often only in respect to HA. Stimulated secretions were also saturated in regard to TCP and OCP. Some samples of stimulated submaxillary and whole saliva were also saturated in regard to DCPD, while only few samples were supersaturated in this regard.
