Abstract
Abstract Cariogenic substances such as foodstuffs are treated to incorporate a soluble source of calcium or phosphate ions to provide a product of calcium and phosphate ion concentrations in fluids of salivary retention areas preclusive of carious dissolution of dental enamel. In non-aqueous foodstuffs, the calcium or phosphate ion source should be at least as rapidly soluble as cariogenic, e.g., carbohydrate, components therein. Also provided are mouth rinse solutions comprising a soluble source of calcium or phosphate ions and an osmotically active agent effective in delivering such ions to fluids trapped in salivary retention areas.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
Sucrose in crystalline form having a soluble source of calcium ions uniformly distributed therethrough as a result of dissolution of the sucrose and soluble source of calcium ions in water and the subsequent evaporation of the water solvent, said calcium ion source being present in a quantitative weight ratio such that upon dissolution of one gram of sucrose there is also dissolved a sufficient quantity of said soluble source of calcium ions to supply to the resulting solution at least 3.25 mg of calcium ions.
Claim 2
Dependent Claim
85 words
Sucrose in crystalline form having a soluble source of calcium ions uniformly distributed therethrough as a result of dissolution of the sucrose and soluble source of calcium ions in water and the subsequent evaporation of the water solvent, said calcium ion source being present in a quantitative weight ratio such that upon dissolution of one gram of sucrose there is also dissolved a sufficient quantity of said soluble source of calcium ions to supply to the resulting solution at least 3.25 mg of calcium ions.
Claim 3
Dependent Claim
85 words
Sucrose in crystalline form having a soluble source of phosphate ions uniformly distributed therethrough as a result of dissolution of the sucrose and soluble source of phosphate ions in water and the subsequent evaporation of the water solvent, said phosphate ion source being present in a quantitative weight ratio such that upon dissolution of one gram of sucrose there is also dissolved a sufficient quantity of said soluble source of phosphate ions to supply to the resulting solution at least 1.08 mg of phosphate ions.
Claim 4
Dependent Claim
85 words
Sucrose in crystalline form having a soluble source of phosphate ions uniformly distributed therethrough as a result of dissolution of the sucrose and soluble source of phosphate ions in water and the subsequent evaporation of the water solvent, said phosphate ion source being present in a quantitative weight ratio such that upon dissolution of one gram of sucrose there is also dissolved a sufficient quantity of said soluble source of phosphate ions to supply to the resulting solution at least 1.08 mg of phosphate ions.
Claim 5
Dependent Claim
112 words
A foodstuff containing sucrose in crystalline form having a soluble source of calcium ions uniformly distributed therethrough as a result of dissolution of the sucrose and the soluble source of calcium ions in water and the subsequent evaporation of the water solvent, said calcium source being present in a quantitative weight ratio such that, taking into account any differences in the rate of dissolution of sucrose and the soluble source of calcium ions under the conditons of dissolution, upon dissolution of one gram of sucrose there is also dissolved a sufficient quantity of said soluble source of calcium ions to supply to the resulting solution at least 3.25 mg of calcium ions.
Claim 6
Dependent Claim
112 words
A foodstuff containing sucrose in crystalline form having a soluble source of calcium ions uniformly distributed therethrough as a result of dissolution of the sucrose and the soluble source of calcium ions in water and the subsequent evaporation of the water solvent, said calcium source being present in a quantitative weight ratio such that, taking into account any differences in the rate of dissolution of sucrose and the soluble source of calcium ions under the conditons of dissolution, upon dissolution of one gram of sucrose there is also dissolved a sufficient quantity of said soluble source of calcium ions to supply to the resulting solution at least 3.25 mg of calcium ions.
Claim 7
Dependent Claim
113 words
A foodstuff containing sucrose in crystalline form having a soluble source of phosphate ions uniformly distributed therethrough as a result of dissolution of the sucrose and the soluble source of phosphate ions in water and the subsequent evaporation of the water solvent, said phosphate ion source being present in a quantitative weight ratio such that, taking into account any differences in the rate of dissolution of sucrose and the soluble source of phosphate ions under the conditions of dissolution, upon dissolution of one gram of sucrose there is also dissolved a sufficient quantity of said soluble source of calcium ions to supply to the resulting solution at least 1.08 mg of calcium ions.
