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 ##STR00001## 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.
