Abstract: A device for treating a root canal in a tooth including a fixture piece having a lumen and a distal tip, a first electrode in communication with the lumen, and a sonic or ultrasonic energy source. The first electrode is configured to deliver electrical energy to an irrigating fluid passing through the lumen prior to discharge from the distal tip. Sonic or ultrasonic energy source is provided from the fixture piece for delivery of sonic or ultrasonic energy to the root canal. A fluid supply line or replaceable cartridge can be provided to delivery irrigating fluid to the fixture piece. A method for treatment of a root canal and kit assembly are further provided.

Abstract: A method for preventing infections during an endodontic procedure comprises removing pulp material from a pulp canal and inserting a temporary antibacterial material, such as a sponge or pellet, into the resulting pulp cavity. The antibacterial material comprises an absorbent material embedded with an antibacterial composition. Optional components that can also be embedded in the antibacterial material include hemostatic agents, colorants, and radiopaque materials. A temporary restoration is applied over the pulp canal and antibacterial material for a desired time period, after which the temporary restoration and antibacterial sponge are removed and a permanent filling is introduced into the root canal and a permanent restoration is attached to the tooth. Because temporary restorations often leak bacteria-laden saliva, the antibacterial sponge prevents infections arising from such bacteria while the temporary restoration is in place.
