Cleaning of long oval canals with WaveOne Gold system associated with different irrigant agitation protocols

Aim: The aim of the study was to evaluate cleaning mandibular incisors with WaveOne Gold® (WO) under different preparation techniques. Methods: A total 210 human were selected and divided into seven groups (n = 30), prepared by WO single-files (Small 20/.07 – WOS; Primary 25/.07 WOP; Medium 35/.06 WOM; or Large 45/.05 - WOL) sequential-file techniques (WOS WOS WOL). Further subdivision made according irrigation protocol: control group (manual CON), E1 Irrisonic® EIR, EDDY® EDD. Debris removal smear layer evaluated scanning electron microscopy. Data analyzed using Spearman’s correlation test. significance level set at 5%. Results: For debris removal, WOP, EIR differed from CON EDD (p <0.05). Conclusion: Regardless instrumentation used, agitation irrigant solution provided better cleanability. These findings reinforce need for as adjuvants in root canal systems incisors.
