Abstract
Abstract The use of edible cyclotriphosphates and cyclotetraphosphates as phosphorous supplements in diets effectively inhibit the development of caries. The compounds may be incorporated in candies, for example, caramels, they may also be imbedded in fat particles, which in turn are distributed throughout a food composition such as a cereal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
38 words
A method of inhibiting caries in live human teeth which comprises orally administering to the human a non-toxic cariostatic amount of a cyclic phosphate of the formula ##STR2## where M is sodium or potassium, in an ingestible carrier.
Claim 2
Independent Claim
38 words
A method of inhibiting caries in live human teeth which comprises orally administering to the human a non-toxic cariostatic amount of a cyclic phosphate of the formula ##STR2## where M is sodium or potassium, in an ingestible carrier.
Claim 3
Dependent Claim
24 words
The method of claim 1 where the cariostatic amount of the cyclic phosphate is from 0.05 to 3% by weight computed as elemental phosphorus.
Claim 4
Dependent Claim
12 words
The method of claim 1 where the carrier is sticky and viscous.
Claim 5
Dependent Claim
12 words
The method of claim 1 where the carrier is a lard fat.
