BACKGROUND Evaluation of the additive effect of photodynamic therapy (PDT) on the antibacterial activity of 2.5% sodium hypochlorite (NaOCl) and QMix against 6-week Enterococcus faecalis biofilms contaminated root canals. AIMS To establish the most suitable irrigant for eradication of 6-week E. faecalis biofilms. SETTINGS AND DESIGN In vitro study. MATERIALS AND METHODS A 6-week E. faecal...

Objective: To investigate the effects of surface preparation with sodium hypochlorite (NaOCl) on bracket shear bond strength and amount residual adhesive primary permanent teeth. Materials Methods: 24 premolars, 12 in each group (groups I III), molars, II IV) were included. In II, 37% phosphoric acid was applied to tooth surfaces, without using any other agent. Group III IV, 5.25% NaOCl first a...

BACKGROUND Sodium hypochlorite (NaOCl) is the most widely used endodontic irrigant because of its excellent antimicrobial, organic tissue dissolving, and lubricating properties. However, it is highly cytotoxic to the periapical tissues. AIM This study evaluated in vitro the extrusion of 5.25% NaOCl through the apical foramina of mesiobuccal (MB) root canals of maxillary first molars in two ex...

AIM: To monitor chlorine consumption from nonagitated aqueous sodium hypochlorite (NaOCl) solutions in human root canals using a recently developed assay, which can determine the order of magnitude of available chlorine in small volumes of liquid. METHODOLOGY: The root canals of 80 extracted single-rooted human teeth were instrumented to ProTaper Universal F4 and irrigated using 1% NaOCl. Subse...

BACKGROUND AND OBJECTIVES Peritoneal dialysis (PD) is a common maintenance renal replacement modality for children with ESRD frequently compromised by infectious peritonitis and catheter exit site and tunnel infections (ESI/TI). The effect of topical mupirocin (Mup) and sodium hypochlorite (NaOCl) solution was evaluated as part of routine daily exit site care on peritonitis and ESI/TI rates, ca...

Background The aim of the present study was to compare the amount of the smear layer remaining in prepared root canals with different protocols of Bio RaCe files and XP-endo Finisher file (XPF) in association with 17% EDTA and sodium hypochlorite solution. Material and Methods A total of 68 extracted single-rooted teeth were randomly divided into 4 experimental groups (n=14) and two control g...

Since natural alternatives are needed in dentistry for the treatment of root canal, where standard irrigant is NaOCl with significant toxicity, aim study was to assess antibacterial properties non-chemical root-canal irrigants (aqueous extracts oregano, thyme, lemongrass, melaleuca and clove essential oils) against Enterococcus faecalis. For this, aqueous each oil (AqEO) were prepared. A soluti...

Irrigation has been performed in conjunction with endodontic therapy for many years. One of the primary reasons for irrigating the root canal system is to ensure cleanliness of the canals prior to obturation. This cleanliness involves both elimination of microorganisms and removal of organic matter. Sodium hypochlorite [NaOCl] is the most commonly used solution in root canal treatments, despite...

Background: Bleaching agents have evolved in improving the appearance of discolored teeth. These agents can be hydrogen peroxide, carbamide peroxide or other proprietary material that breaks down into water and oxygen. The dissociated products penetrate through pores of enamel and dentine changing the value of the tooth. Some of the materials used in endodontics as an irrigant have mechanism of...

OBJECTIVE This clinical study was undertaken to compare the effectiveness of 2.5% sodium hypochlorite (NaOCl) and 0.12% chlorhexidine digluconate as irrigants in reducing the cultivable bacterial populations in infected root canals of teeth with apical periodontitis. STUDY DESIGN According to stringent inclusion/exclusion criteria, 32 teeth with primary intraradicular infections and chronic a...
