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.

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.
