    • Activating endodontic points (28a, 28b) and/or other dental tools are sized and configured to be placed in the root canal (12) of a tooth (10). The activating endodontic points (28a, 28b) or dental tools are coated or impregnated with a curing agent that initiates or accelerates polymerization of a sealer or filler composition (32) when placed in contact with the sealer or filler material (32). Curing agents can include amines that can destabilize a peroxide in the sealer or filler material (32) to initiate or accelerate polymerization, or they may comprise 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.

    • A dental handpiece for the endodontic treatment of a root canal, comprising
      (i) a chuck for attaching and holding an endodontic file;
      (ii) an electric motor having a shaft for driving the endodontic file;
      (iii) a control unit for controlling the motor, which receives a stream of input data;

      characterized in that while monitoring the stream of input data, the control unit determines the current absorbed by the electric motor, and controls the motor so that the file alternates the direction of rotation at a frequency of from 1 to 20 Hz between a first direction and a second direction opposite to the first direction, and whereby the control unit controls the electric motor so that the file continuously rotates in the second direction when the monitored data fulfils a predetermined torque threshold condition during rotation in the first direction.

    • A rinsing instrument (1) is described, comprising a vibration part (30) and a spraying part (20) which can be coupled to each other. The spraying part comprises: a hollow cylindrical body (21) with an input end (23) and a narrow needle (25); an axially displaceable piston (22) arranged in the interior of the body, which at its free side directed away from the spraying mouth is provided with a coupling member (27) for coupling to the vibration part, for instance a threading. The vibration part comprises: a housing (31) which at an end is provided with a coupling member (32) for coupling to the spraying part, for instance a threading; a vibration generator (34) mounted in the housing, for instance a motor; a battery chamber (39) for receiving a battery (35) providing electrical supply to the vibration generator; a user-controllable switch (36) mounted in the housing for actuating the vibration generator.
