The use of chelating agents with passive ultrasonic irrigation enhances root canal filling sealing ability

The aim of this study was to compare the influence a final rinse with and without passive ultrasonic irrigation (PUI), using 17% ethylenediaminetetraacetic acid (EDTA) or 10% citric (CA), 2.5% sodium hypochlorite (NaOCl) PUI, on sealing ability root canal fillings. Root instrumentation performed in single-rooted premolars NaOCl as irrigant. Subsequently, roots were randomly allocated into four experimental groups (n=23): EDTA+PUI, EDTA, CA+PUI, CA control group: NaOCl+PUI. specimens root-filled gutta-percha resin-based sealer inserted device measure glucose leakage at 7 30 days. Kruskal-Wallis Mann- Whitney tests used evaluate differences between solutions PUI. Friedman’s ANOVA time points (P<0.05). PUI showed lower infiltration values (EDTA+PUI 0.74±0.77 CA+PUI 5.32±1.45) when compared which not (EDTA 7.20±2.18 20.73±4.70), difference significant for EDTA (P<0.01) (P=0.000). Also, less than CA, (P<0.005). NaOCl+PUI higher cumulative (22.92±9.71). A enhances infiltration.
