Abstract: An endodontic irrigation needle includes a connection fitting, needle, and apical plug. The needle includes a proximal end joined to the connection fitting, is hollow and forms a conduit for irrigation fluid and a plurality of exit ports for discharging irrigation fluid. An apical plug is formed of a different material than the needle and is permanently bonded to the distal end of the needle. The apical plug may be formed of an elastomeric material such as rubber. The apical plug may be wedge-shaped and include two or more layer portions joined by one or more flexible connecting portions. The layer portions may include a wedge-shaped tip layer, a disc-shaped mid layer, and a tapered top layer. A method for endodontic irrigation includes abutting an apex opening of a root canal with the apical plug, and discharging irrigation fluid through the exit ports of the needle.

Abstract: A system and method for treating a necrotic tooth in a root canal and includes using a dual function double barrel reciprocating syringe in conjunction with a dual channel needle to provide both an irrigant for irrigation and aspiration of the irrigant and organic debris within the necrotic tooth. Once optimally positioned and secured in place by a rubber seal, root canal of the tooth can be treated through irrigation and aspiration of the dual channel needle.

Abstract: The endodontic point containing ultrasonic deformable material is a filler for root canal therapy that decreases in viscosity when subjected to ultrasonic waves. Once the point is inserted into a prepared tooth space, such as a prepared and cleaned root canal, the point is subjected to ultrasonic waves. The ultrasonic waves cause the viscosity of the point to lower, thus allowing the point to flow into voids in the tooth space and allow air to escape from the voids. The point then hardens and remains in the shape acquired when at low viscosity once application of the ultrasonic waves is stopped.
