Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
An oral composition effective in inhibiting formation of dental calculus, said composition comprising (1) a bis(carboxyalkoxy)-butanedioic acid compound selected from the group consisting of acids having the structural formula: ##STR6## wherein R is hydrogen or lower normal alkyl and each R can be the same as or different from any other R in said formula, and pharmaceutically acceptable salts of said acids and (2) a carrier suitable for use in the oral cavity, said compound being present in said composition in amount and concentration sufficient to substantially inhibit formation of dental calculus, said composition being selected from the group consisting of oral hygiene products and chewing gums.
Claim 2
Dependent Claim
107 words
An oral composition effective in inhibiting formation of dental calculus, said composition comprising (1) a bis(carboxyalkoxy)-butanedioic acid compound selected from the group consisting of acids having the structural formula: ##STR6## wherein R is hydrogen or lower normal alkyl and each R can be the same as or different from any other R in said formula, and pharmaceutically acceptable salts of said acids and (2) a carrier suitable for use in the oral cavity, said compound being present in said composition in amount and concentration sufficient to substantially inhibit formation of dental calculus, said composition being selected from the group consisting of oral hygiene products and chewing gums.
Claim 3
Dependent Claim
27 words
A composition according to claim 1 wherein each R in said formula is hydrogen and said composition being selected from the group consisting of oral hygiene products.
Claim 4
Dependent Claim
23 words
A composition according to claim 1, said compound being selected from the group consiting of alkali metal and ammonium salts of said acids.
Claim 5
Dependent Claim
39 words
a composition according to claim 3 said composition being selected from the group consisting of toothpastes having a pH between about 4 and about 11, said concentration being between about 0.1% and about 5% by weight of said composition.
Claim 6
Dependent Claim
25 words
A method for inhibiting formation of dental calculus which comprises introducing into an oral cavity containing exposed dental surfaces a composition according to claim 1.
Claim 7
Dependent Claim
25 words
A method for inhibiting formation of dental calculus which comprises introducing into an oral cavity containing exposed dental surfaces a composition according to claim 3.
Claim 8
Dependent Claim
25 words
A method of inhibiting formation of dental calculus which comprises introducing into an oral cavity containing exposed dental surfaces a composition according to claim 2.
