Abstract
The invention relates to compositions for treating tooth and/or bone tissue that contain calcium phosphates, calcium fluorides or calcium fluorophosphates, all of which being poorly soluble in water, and polyelectrolytes. The compositions can be cured and are suited for the smoothing, the reconstruction, and the remineralizing treatment of tooth and bone tissue, especially for eliminating microroughnesses.
Claims19
A composition for treating tooth and/or bone tissue, comprising
- (a) a calcium salt of low solubility in water, selected from phosphates, fluorides and fluorophosphates, which optionally may additionally contain hydroxyl and/or carbonate groups, where the calcium salts are in the form of nanoparticulate primary particles with an average particle diameter in the range from 5 to 300 nm, and
- (b) a polyelectrolyte.
