Activating endodontic points and dental tools are sized and configured to be placed in the root canal of a tooth. The activating endodontic points or dental tools are coated or impregnated with a curing agent that initiates or accelerates polymerization of a sealer or filler composition when placed in contact with the sealer or filler material. Curing agents can include amines that can destabilize a peroxide in the sealer or filler material to initiate or accelerate polymerization, or they may comprise the peroxide. An implement can be dipped in a concentrated curing composition just prior to inserting the implement into a root canal to contact the filler or sealer composition. Kits may include a plurality of curing agent compositions having different concentrations and/or amounts of curing agent. Kits may also include a curable resin material that includes a first part of a multi-part curing system and a curing composition that includes, as curing agent a complementary part of the curing system.

Compositions, kits and methods for initiating or accelerating curing of endodontic filler or sealer compositions placed on a root canal

Kits and methods facilitate chair-side coating of an endodontic cone for improved sealing between the hydrophilic root canal tissue, the hydrophobic elastomer substrate of the endodontic cone, and a hydrophilic sealing resin. The kit includes one or more endodontic cones (e.g., formed of gutta percha) and a micro-dose container containing an adhesive composition. The practitioner can dip the cones into the adhesive composition so as to coat the cones chair-side, just prior to use. The adhesive composition includes an adhesive resin compound comprising at least one hydrophobic region and at least one hydrophilic region. The hydrophobic region is compatible with the hydrophobic elastomer substrate of the endodontic cone, while the hydrophilic region is compatible with a hydrophilic endodontic sealing resin.

Curing agents can include amines that can destabilize a peroxide in the sealer or filler material to initiate or accelerate polymerization. Kits are also disclosed that include a plurality of endodontic points or dental tools that have different concentrations of curing agent coated on or impregnated within the endodontic points or dental tools such that the endodontic points or dental tools have different cure times. In another kit, a plurality of curing agent compositions are provided for dipping a substrate to coat or impregnate substrates having different concentrations of curing agent.
