Apical Pressure and Extrusion Generated by the TruNatomy Irrigation Needle and Other Various Irrigation Systems

Abstract

Irrigant extrusion outside of root canals may occur when excessive apical fluid pressures are produced. Currently, no studies have reported the apical pressure produced by the TruNatomy irrigation needle (TNI). The aim of this study was to investigate the relative apical pressure and extrusion produced by the TNI and other irrigation delivery method and adjuncts. A polycarbonate root canal model was instrumented to an ISO #40 with 0.04 taper. Irrigant was delivered at a rate of 2mL/min for 1 minute with side-vented needle irrigation (SNI), TNI, and the EndoVac master delivery tip (MDT). The following irrigation adjuncts were activated while delivering irrigant into the model: EndoActivator (EA), passive ultrasonic irrigation (PUI), EndoVacmicro-cannula (EV), and the XP-3D Finisher (XPF). Apical pressure was measured by a manometer attached to the model, and the amount of apical irrigant extrusion was measured as a function of mass.
