Abstract
Abstract A prophylactic dental paste for professional use containing at least 60 percent by weight of dicalcium phosphate, (which may be anhydrous dicalcium phosphate, dicalcium phosphate dihydrate or a mixture of the two) not only satisfactorily cleans the tooth surface but provides a tooth with higher luster or polish. The use of the pro- phylatic dental paste of the invention, in which the dicalcium phosphate has the same calcium to phosphorus atom ratio found in the tooth, aids in remineralization of the cleaned tooth surface.
