Abstract

Abstract An oral composition such as a toothpaste (including gel or cream), mouthwash, lozenge, chewing gum or tooth powder containing a calculus-inhibiting amount of a linear molecularly dehydrated polyphosphate salt and, to inhibit enzymatic hydrolysis of said polyphosphate salt in saliva, a combination of a fluoride ion-providing source and a synthetic linear polymeric polycarboxylate.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 84 words
A method of inhibiting the occurrence of calculus on tooth surfaces as by inhibiting the transformation of amorphous calcium phosphate to a hydroxapatite crystal structure normally associated with calculus comprising applying to such tooth surfaces a calculus inhibiting amount of anticalculus oral composition containing in an orally acceptable vehicle one or a mixture of water soluble tripolyphosphate salts as essential anticalculus agents, and an amount of dentally acceptable fluoride ion source sufficient to supply about 25 ppm. to about 2,000 ppm. of fluoride ions.
Claim 2
Independent Claim 84 words
A method of inhibiting the occurrence of calculus on tooth surfaces as by inhibiting the transformation of amorphous calcium phosphate to a hydroxapatite crystal structure normally associated with calculus comprising applying to such tooth surfaces a calculus inhibiting amount of anticalculus oral composition containing in an orally acceptable vehicle one or a mixture of water soluble tripolyphosphate salts as essential anticalculus agents, and an amount of dentally acceptable fluoride ion source sufficient to supply about 25 ppm. to about 2,000 ppm. of fluoride ions.
Claim 3
Dependent Claim 18 words
