As used herein, the term "partially water-soluble" with respect to the calcium salt component refers to a calcium salt having a solubility which is greater than that of dicalcium phosphate dihydrate in an aqueous solution having a pH of about 7.0 and a temperature of about 25� C. but which is less than that solubility which would release more than about 1400 ppm of calcium cations in such aqueous solution. In an aqueous solution having a pH of about 7.0 at a temperature of about 25� C., dicalcium phosphate dihydrate generally releases about 40 ppm of calcium cations. Thus, the calcium salt used in the present invention generally has a solubility such that the salt is capable of releasing more than about 40 ppm but no more than about 1400 ppm of calcium cations in an aqueous solution having a pH of about 7.0 at a temperature of about 25� C. Preferably, the calcium salt(s) used in this invention has a solubility in such aqueous solution such that the salt(s) releases from about 100 ppm to no more than about 1400 ppm of calcium cations.
The term "water-soluble" as used herein with respect to the phosphate, fluoride and divalent metal salts suitable for use in the present invention refers to a solubility such that the salts are each capable of releasing at least about 1400 ppm of ions into an aqueous solution having a temperature of about 25� C. and a pH of about 7.0.
