Abstract

A dental composition compatible with acidic dental primers/adhesives, the dental composition comprising (A) 5% (w/w) to 90% (w/w) of at least one polymerizable monomer having at least one ethylenically unsaturated vinyl, acrylate, or methacrylate group; (B) 0.01% (w/w) to 10% (w/w) of at least one compound of structure where each of R1, R2, and R3 may be the same or different and is independently selected from H, alkyl, alkoxyl, aryl, acyl, allyl, pyridyl, —OH, alkenyl, aralkyl, cycloalkyl, and heterocyclic structure containing O, S, or N; (C) 0.01% (w/w) to 10% (w/w) of at least one hydroperoxide compound with at least one hydroperoxide groups attached to a tertiary carbon; (D) 5% (w/w) to 95% (w/w) of at least one finely divided filler; (E) 0% (w/w) to 25% (w/w) of one or more components selected from a solvent, a photoinitiator, a stabilizer, and/or an antimicrobial agent. One embodiment of the invention is a dental cementation or core buildup kit that has enhanced compatibility between the acidic primer/adhesive and the cement or core buildup material, and therefore enhanced adhesion to a tooth. The kit includes (I) an acidic primer/adhesive composition having a pH less than 4.5; and (II) a cement or core buildup material having the above described composition comprising components (A)-(E). Another embodiment of the invention is a method for adhering a prosthetic device to a tooth to restore the function and/or appearance of a diseased tooth. Another embodiment of the invention is a method of providing a temporary cement, crown and/or bridge, inlay, onlay, endodontic sealer, and/or an endodontic filling material, using the inventive composition.
