Abstract
Experimental dental caries in rats was significantly inhibited by the orthophosphates, Ca(H2PO4). H2O, Ca3(PO4)2 and (NH4)2 HPO4 and by the metaphosphates Na(PO3)n and Na(PO3)6. Victamide (an ammonium-P2O5 complex) as well as (KPO3)n did not significantly reduce caries incidence and were less effective in reducing caries severity scores than the other inorganic phosphates. Organic phosphates uniformly cariostatic to a significant extent were the following: phytin, sodium-phytate, calcium-phytate and [beta]-glycerol-phosphate.
