Patent ID: 8383163

Claim:
A fluoride varnish composition for temporary application to a person's tooth surfaces, comprising: a sticky, adhesive liquid carrier phase for application and temporary adhesion to tooth surfaces, the liquid carrier phase comprising: a substantially water-insoluble resin included in an amount in a range of about 30% to about 80% by weight of the fluoride varnish composition; and an adhesion promoting agent that promotes adhesion of the fluoride varnish composition to tooth surfaces, the adhesion promoting agent comprising an organo phosphoric acid having at least one alkyl group and included in an amount in a range of about 1% to about 20% by weight of the fluoride varnish composition, and wherein the sticky, adhesive liquid carrier phase comprising the substantially-water insoluble resin and the adhesion promoting agent adheres temporarily to exposed tooth surfaces; and a fluoride ion source dispersed within the sticky, adhesive liquid carrier phase, wherein the fluoride varnish composition has a viscosity and consistency so as to facilitate painting of the composition onto tooth surfaces and wherein the adhesion promoting agent improves adhesion of the fluoride varnish composition to the tooth surfaces.
