Abstract: The present invention is directed to an etchant/primer composition, an etchant/primer/adhesive monomer composition, kits using the same and methods using the same for improved bonding to dental structures. The etchant/primer composition comprises a compound having the formula: RN(CH2YCO2M)2 wherein R=R1 or R2; R1=an aromatic group; R2=a conjugated unsaturated aliphatic group; Y=a single bond, CH2, CHCH3 or C═CH2; and each M is independently H, an alkali metal, an alkaline earth metal, aluminum, a transition or redox metal or an alkyl group having 1 to 18 carbon atoms, with the proviso that when both M groups are alkyl groups, said compound is capable of being easily hydrolyzed, displaced, or exchanged with other reagents present in the etchant/primer composition, a polar solvent system, and nitric acid.

Abstract: Continuous fibers, resin-fiber pastes, or continuous fiber-reinforced preforms are inserted into tooth cavities to form high-strength dental restorations. The fibers may be mixed or coated with a resin monomer and may be used with fillers such as fluoride-releasing fillers and colorants. The resin-fiber mixture may be hardened into preforms suitable for inserting into tooth cavities. Conventional filling materials such as composite resins and glass ionomers may be used to complete the restoration. Other applications include endodontic posts, retention pins, provisional restorations, and indirect restorations. Fiber reinforcement results in strength, toughness and elastic modulus (stiffness) several times greater than those of currently available direct-filling composite resins. The fiber performs are easily handled and placed into tooth cavities; the restorations are aesthetic and wear compatible, and release fluoride.
