摘要：
A consumable tip assembly for use with a dental tool and a system forirrigation of atooth root canal. The dental tool has an ultrasonic energy generatorpositionedtherein. The tip assembly provides a single continuous flow path fordelivering fluidfrom a reservoir at the proximal end of the needle to a root canal of a toothat thedistal end of the needle, the distal end of the needle including a closed tipand atleast one circumferential side-vented opening. Energy generated by anultrasonicenergy generator is translated into movement of a needle to provide optimumcleaning to the root canal. The system also includes a pressure source ofirrigationfluid connected to the tip assembly. The irrigation fluid has ultrasonicenergy imposedthereon as it passes through a hand piece of the dental tool.
