Comparison of the Vibringe System with Syringe and Passive Ultrasonic Irrigation in Removing Debris from Simulated Root Canal Irregularities

IntroductionThe aim of this study was to compare the efficiency of a sonic device (Vibringe), syringe irrigation, and passive ultrasonic irrigation in the removal of debris from simulated root canal irregularities.MethodsRoot canals with 2 standardized grooves in the apical and coronal parts were filled with dentin debris. Three different irrigation procedures were performed with NaOCl (1%) and (1) syringe irrigation, (2) Vibringe, and (3) passive ultrasonic irrigation. The amount of remaining debris was evaluated by using a 4-grade scoring system.ResultsUltrasonic irrigation removed debris significantly better from the artificial canal irregularities than the Vibringe System and syringe irrigation (P < .0001). The Vibringe System demonstrated significantly better results than syringe irrigation in the apical part of the root canal (P = .011).ConclusionsPassive ultrasonic irrigation is more effective than the Vibringe System or syringe irrigation in removing debris. The sonic device demonstrated significantly better results than syringe irrigation in the apical root canal third.
