Abstract
The invention provides an anion-containing calcium phosphate compound, composition and dental patch comprising the same and their use in remineralizing teeth. The anion-containing calcium phosphate compound has the following formula: (Ca+2)x(anion−a)y(PO4−3)z wherein 2x=(a*y+3z); a is an integer of 1 to 3; and each of x, y and z is not 0.
Claims14
A non-crystalline anion-containing calcium phosphate complex which is calcium lactate phosphate complex with the formula:
- Ca92+(CH3CHOHCOO−)12(PO43−)2 wherein the calcium lactate phosphate complex has a unit containing calcium phosphate in a core and calcium lactate surrounding the unit containing calcium phosphate surrounding the calcium phosphate,
- wherein binding between the calcium phosphate and lactate anions depends on ion-ion bonding.
