Abstract

Fluoride varnish compositions for temporary application and adhesion to a person'"'"'s teeth. The composition includes a carrier comprising a resin and an adhesion promoting agent comprising an alkyl phosphoric acid. A fluoride ion source (e.g., a fluoride salt such as sodium fluoride) is dispersed within the carrier so as to provide biologically available fluoride ions to the tooth tissue being treated. The composition adheres only temporarily to tooth tissue (e.g., for a period of at least about 4 minutes, but not more than about 1 year), after which the composition spontaneously wears away as a natural result of the action of the tongue, saliva and/or other factors.

Claims

1. A fluoride varnish composition for temporary application to a person'"'"'s teeth, comprising:

a carrier comprising a resin and an adhesion promoting agent, the adhesion promoting agent comprising an organo phosphoric acid having at least one alkyl group, and wherein the carrier adheres temporarily to exposed tooth surfaces; and

a fluoride ion source dispersed within the carrier.

2. A fluoride varnish composition as recited in claim 1, wherein the fluoride varnish composition is substantially colorless.

3. A fluoride varnish composition as recited in claim 1, wherein the fluoride varnish composition remains adhered to the person'"'"'s teeth so as to provide fluoride treatment to the teeth for at least about 2 hours.

4. A fluoride varnish composition as recited in claim 1, wherein the fluoride varnish composition remains adhered to the person'"'"'s teeth so as to provide fluoride treatment to the teeth for at least about 1 day.

5. A fluoride varnish composition as recited in claim 1, wherein the fluoride varnish composition is formulated so as to degrade or spontaneously wear away in less than about 90 days after being placed on a tooth.

6. A fluoride varnish composition as recited in claim 1, wherein the fluoride varnish composition is formulated so as to degrade or spontaneously wear away in less than about 5 days.

7. A fluoride varnish composition as recited in claim 1, wherein the organo phosphoric acid comprises an alkyl phosphoric acid.

8. A fluoride varnish composition as recited in claim 7, wherein the alkyl phosphoric acid comprises an alkyl group having from about 3 to about 30 carbon atoms.

9. A fluoride varnish composition as recited in claim 7, wherein the mono-alkyl phosphoric acid comprises an alkyl group having from about 10 to about 25 carbon atoms.

10. A fluoride varnish composition as recited in claim 7, wherein the mono-alkyl phosphoric acid comprises an alkyl group having from about 15 to about 22 carbon atoms.

11. A fluoride varnish composition as recited in claim 7, wherein the mono-alkyl phosphoric acid comprises at least one of hexadecyl phosphoric acid or docosyl phosphoric acid.

12. A fluoride varnish composition as recited in claim 1, wherein the organo phosphoric acid is included in a range of about 1% to about 20% by weight of the fluoride varnish composition.

13. A fluoride varnish composition as recited in claim 1, wherein the organo phosphoric acid is included in a range of about 3% to about 10% by weight of the fluoride varnish composition.

14. A fluoride varnish composition as recited in claim 1, wherein the resin comprises a natural resin.

15. A fluoride varnish composition as recited in claim 14, wherein the natural resin comprises at least one of shellac or colophonium.

16. A fluoride varnish composition as recited in claim 1, wherein the fluoride varnish composition further comprises at least one rheology modifying agent.

17. A fluoride varnish composition as recited in claim 16, wherein the rheology modifying agent comprises fumed silica.

18. A fluoride varnish composition as recited in claim 1, wherein the fluoride varnish composition further comprises at least one of a sweetener or flavorant.

19. A fluoride varnish composition as recited in claim 1, wherein the fluoride ion source comprises at least one of NaF, BiF₃, SnF₂, ZnF₂, KF, CaF₂, ZrF₄, sodium mono-fluorophosphate (Na₂FPO₃), hexafluorosilicic acid, or sodium hexafluorosilicate.

20. A fluoride varnish composition as recited in claim 1, wherein the fluoride ion source is included in an amount from about 1% to about 8% by weight of the fluoride varnish composition.

21. A fluoride varnish composition as recited in claim 1, wherein the fluoride ion source is included in an amount from about 3% to about 7% by weight of the fluoride varnish composition.

22. A fluoride varnish composition for temporary application to a person'"'"'s teeth, comprising:

a carrier comprising a resin and an adhesion promoting agent, the adhesion promoting agent comprising a mono-alkyl phosphoric acid, the alkyl group having from about 3 to about 30 carbon atoms and wherein the carrier adheres temporarily to tooth tissue; and

a fluoride ion source dispersed within the carrier.

23. A fluoride varnish composition for temporary application to a person'"'"'s teeth, comprising:

a carrier comprising a natural resin and an adhesion promoting agent, the adhesion promoting agent comprising at least one of hexadecyl phosphoric acid or docosyl phosphoric acid, wherein the carrier adheres temporarily to tooth tissue; and

a fluoride ion source dispersed within the carrier.
