“…36 The reduction in root canal debris after performing PUI has been reported by several studies. 4,7,11,37 As expected, in the present study, PUI decreased the percentage of debris in the middle third after preparation with PDL and HEDM. However, PUI did not reduce the percentage of debris in the apical third.…”

“…Having increased the mechanical cleaning efficiency of the root canal system by providing efficient flow dynamics, acoustic streaming, which is highly effective in the penetration of irrigation solution into the dentinal tubule, is more efficient than conventional needle irrigation groups in irrigation solutions to reach the working length. In the present study, this can be considered as one of the possible reasons for the statistically significant difference between the PUA and the CSI methods (Bueno et al, 2019;Rödig et al, 2010).…”

“…Thus, NaOCl gel may be safer due to its minor apical extrusion tendency ( Nesser & Bshara, 2019 ). Passive ultrasonic irrigation (PUI) improves RCS disinfection ( Plotino et al ., 2007 ), removing the smear layer and vapor lock during endodontic treatment ( Bueno et al ., 2019 ; Dioguardi et al ., 2019 ), and permits greater penetration of irrigants to the dentinal tubules ( Sáinz-Pardo et al ., 2014 ).…”

Background: Sodium hypochlorite (NaOCl) is the most commonly used irrigant in endodontics. The purpose of this study was to evaluate the effect of NaOCl solution (2.5%) and gel (3%) with/without passive ultrasonic irrigation (PUI) on Enterococcus faecalis, Escherichia coli, and their endotoxins, lipopolysaccharide (LPS) and lipoteichoic acid (LTA). Methods: 40 human lower premolars were contaminated with E. coli (ATCC 25922) for 28 days and E. faecalis (ATCC 29212) for 21 days. Specimens were randomly divided into four groups: (1) 2.5% NaOCl irrigating the canals without PUI activation; (2) 2.5% NaOCl with PUI; (3) 3% NaOCl gel irrigating the canals without PUI; and (4) 3% NaOCl gel with PUI. 40 mL of irrigant was used for each group. PUI activation was carried out using E1-Irrisonic stainless-steel tip at 10% frequency. After treatment, all specimens were filled with 3mL of 17% ethylenediaminetetraacetic acid (EDTA) for 3min and then washed with nonpyrogenic saline solution. Three samples were collected from the canals: S1, at baseline to confirm biofilm formation; S2 after treatment; and S3 after EDTA. Samples were assessed for E. coli and E. faecalis colony forming units, and LPS and LTA were assessed using chromogenic kinetic LAL assay and ELISA, respectively. Data were analyzed by Kruskal-Wallis, Friedmann and Dunn tests with α≤0.05. Results: All groups were effective in reducing the microbial load of E. coli and E. faecalis after treatment without a significant difference among the groups. NaOCl and NaOCl gel groups had no significant difference in reducing LPS and LTA. Statistically increased reduction was seen for NaOCL + PUI and NaOCl gel + PUI compared for groups without PUI. Conclusions: NaOCl gel has the same antimicrobial action of NaOCl solution and can partially detoxify endotoxins. PUI improves NaOCl (gel or solution) action over E. faecalis and E. coli and their endotoxins.
