Abstract
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.
