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

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
