Apical Pressures Generated by the XP-3D Finisher and Irrigation Adjuncts
Abstract
Irrigant extrusion outside of root canals can occur when the central venous pressure (CVP) of 5.88 mm Hg, is exceeded. Extrusion of the common irrigant, sodium hypochlorite, can cause severe pain, swelling, and nerve damage. The XP-3DFinisher (XP3D), a highly flexible adjunct to irrigation, can expand to contact canal walls while rotating at speeds of 1000 RPM. Currently no studies have reported the apical fluid pressure produced by the XP3D. Methods: Apical pressures were measured by manometer attached to a polycarbonate root canal model instrumented to an ISO #40with 0.04 taper. Canals were flooded prior to activation of the following irrigation adjuncts: EndoActivator (EA), passive ultrasonic irrigation (PUI), and the XP3D. The EndoVac and side-vented needle irrigation (SNI) produce negative and positive apical pressures, respectively, and were used for comparison. Results: The XP3D created positive pressure (1.52 mm Hg) similar to EA and PUI but significantly lower than SNI(4.022 mm Hg), which did not surpass the CVP threshold. Pressure produced by theXP3D was the lowest of the adjuncts that produced positive pressure. The EndoVac was the only adjunct that produced negative pressure. Conclusion: The XP3Dproduced an apical pressure below CVP, reducing the chance of irrigant extrusion. No significant difference was observed when compared to the EA or PUI.
