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 filling 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. 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.
