1. A dental applicator comprising a film on a surface of the applicator, wherein: the film comprises at least one activator; andthe at least one activator is dissolved in or dispersed in the film,wherein the film is derived from a composition comprising a film former, and whereinthe film is essentially free from a solvent. 2. The applicator of claim 1, wherein the at least one activator comprises a barbituric acid, a barbituric acid salt, a thiobarbituric acid, a thiobarbituric acid salt, a sulfinic acid, a sulfinic acid salt, or a sulfinic acid ester, or a derivative thereof. 3. The applicator of claim 1, wherein the at least one activator is homogeneously dissolved in, or dispersed in, the film. 4. The applicator of claim 1, wherein the film has a thickness in the range from about 0.5 μm to about 100 μm. 5. The applicator of claim 1, wherein the film former has a molecular weight of at least 1,000. 6. The applicator of claim 1, wherein the film is derived from a film former comprising a natural film former, a semi-synthetic film former, a cellulose derivative, a poly(meth)acrylate, a vinyl polymer, or a polyurethane, or mixtures or combinations thereof. 7. The applicator of claim 1, wherein the applicator comprises a handle. 8. The applicator of claim 1, wherein the applicator is selected from the group consisting of a brush, a sponge, a spatula, or a dental instrument. 9. The applicator of claim 1, wherein the applicator comprises a brush, wherein the brush comprises bristles. 10. The applicator of claim 1, wherein the applicator is a multiuse applicator. 11. A method of using the applicator of claim 1, the method comprising: contacting the film comprising the at least one activator located on the surface of the applicator with at least one polymerizable component and an initiator or initiator system to cure a hardenable composition. 12. The method of claim 11, wherein the at least one polymerizable component comprises a polymerizable moiety comprises an acrylate, a (meth)acrylate, or an epoxide, or a combination thereof. 13. The method of claim 11, wherein the at least one polymerizable component comprises an acid moiety. 14. The method of claim 13, wherein the acid moiety comprises a carboxylic acid, a phosphoric acid, or a sulphonic acid, or a combination thereof. 15. The method of claim 11, wherein the hardenable composition comprises components present in the following amounts: one or more polymerizable components comprising an acid group: from about 2 to about 40 wt.-%;an initiator or initiator system: from about 0.5 to about 8 wt.-%; andone or more activators: from about 0.05 to about 2.0 wt.-%. 16. The method of claim 11, wherein the initiator or initiator system comprises one or more of an oxidizing agent, a reducing agent, a sensitizing agent, an onium salt, or an electron donor. 17. The method of claim 11, wherein the hardened dental material comprises an adhesive, a cement, a filling material, a crown, a bridge, a sealant, or a core build-up material, or combinations or mixtures thereof. 18. A method of making the applicator of claim 1, the method comprising the steps of applying a film former and at least one activator to a surface of the applicator and forming a film on the surface of the applicator. 19. The method of claim 18, wherein the forming step comprises one or more of coating, spraying, dipping, printing, drying, or freeze drying. 20. A kit comprising: the applicator of claim 1; anda polymerizable composition, the polymerizable composition comprising at least one polymerizable component; andan initiator or initiator system. 21. The kit of claim 20, wherein the at least one activator is able to facilitate a hardening reaction of the at least one polymerizable component.
