A method for treating dental caries in humans comprising applying to the affected area an effective amount of a composition comprising from about 0.1% to 20% by weight of a non-toxic sanguinarine salt, from about 1% to about 60% by weight of zinc chloride, and from about 0.4% to about 3.0% by weight of a non-toxic fluoride salt, in a solvent selected from the group consisting of water, glycerine, propylene glycol, dimethyl sulfoxide, and C1-C6 alcohols.
Claim 2
Independent Claim
76 words
A method for treating dental caries in humans comprising applying to the affected area an effective amount of a composition comprising from about 0.1% to 20% by weight of a non-toxic sanguinarine salt, from about 1% to about 60% by weight of zinc chloride, and from about 0.4% to about 3.0% by weight of a non-toxic fluoride salt, in a solvent selected from the group consisting of water, glycerine, propylene glycol, dimethyl sulfoxide, and C1-C6 alcohols.
