| abstract |
an oral care composition is described which comprises a composite material and a physiologically acceptable carrier, wherein the composite material comprises first component material comprising a biomineralizing agent; and second component material capable of reacting with phosphate ions to generate an in situ reaction product of calcium and phosphate which adheres to tooth enamel, dentin or both and which is reactive to the formation of hydroxyapatite, in which the biomineralization comprises amorphous calcium phosphate, a-tricalcium phosphate, ß-tricalcium phosphate, calcium-deficient hydroxyapatite, (ca9 (hpo4) (po4) 5oh), dicalcium phosphate (cahpo4), calcium phosphate dihydrate (cahpo4 · 2h2o ), hydroxyapatite (ca10 (po4) 6 (oh) 2), octacalcium phosphate (ca8h2 (po4) 6 · 5h2o), tetracalcium phosphate (ca4 (po4) 2nd) or one of its mixtures and the second component material comprises calcium oxide , calcium carbonate, calcium hydroxide, calcium sulfate, calcium carboxymethyl cellulose, calcium alginate, citric acid calcium salts, calcium silicate or one of its mixtures. |
