This study was conducted to evaluate the efficacy of sodium hypochlorite (NaOCl, 0-200 mg/kg), thiamine dilauryl sulfate (TDS, 1,000 mg/kg), and ultrasound (37 kHz, 380 W) on reducing Salmonella Typhimurim, mesophilic aerobic bacteria (MAB), and coliforms on chicken skin. Chemical and physical treatments were applied for 5 min either singly or jointly, and Salmonella previously inoculated on ch...

background. this study evaluated the antimicrobial activity of tetraacetylethylenediamine-sodium perborate (taed-sp) in comparison to 2.5% and 5% sodium hypochlorite (naocl) against enterococcus faecalis. methods. a standard suspension of e. faecalis was inoculated on 60 plates containing mueller-hinton agar culture medium. four sterile disks of beckman filtration paper were placed on each plat...

AIM: The study was done to assess the antimicrobial effectiveness of Chitosan Nanoparticles (CNPs), Chlorhexidine (CHX), and their combination (CHX/CNPs) versus that Sodium hypochlorite (NaOCl) in patients with mandibular necrotic premolars evaluate effects on post-operative pain after single-visit endodontic treatment. MATERIALS AND METHODS: Sixty were divided randomly four groups (n = 15) acc...

Background: The persistence of microorganisms in the root canal system is one leading causes treatment failure. Biofilms putative pathogens hidden inside dentin tubules and other ramifications may limit current disinfection protocols. Photodynamic therapy (PDT) with a wavelength 628 nm can be used as an antimicrobial strategy that uses low-power laser energy to activate non-toxic photosensitize...

In dentistry, root canal therapy is the internal cleaning of a complex channel network contained within the tooth. The aim is to disinfect the canal and remove any remaining bacteria to prevent further infection prior to root filling. Irrigant solutions play an important role in this procedure as they allow canal debridement. Sodium hypochlorite (NaOCL) is an irrigant that is clinically recomme...

ABSTRACT The genus Melocactus (“cabeça-de-frade”) comprises 32 species in Brazil, of which M. glaucescens and paucispinus are threatened with extinction. present work evaluated the effects different concentrations Murashige & Skoog (MS, MS/2 MS/4) culture medium sucrose (15 g L-1 30 L-1) on vitro seed germination plant growth efficiency sterilization sodium hypochlorite (NaOCl) when using s...

OBJECTIVES This study evaluated the effect of three antioxidizing agents on pull-out bond strengths of dentin treated with sodium hypochlorite. MATERIALS AND METHODS Root canals of 75 single-rooted human teeth were prepared. Fifteen teeth were irrigated with normal saline for a negative control group, and the remaining 60 teeth (groups 2 - 5) with 2.5% NaOCl. The teeth in group 2 served as a ...

introduction: the purpose of this in vitro study was to assess the antifungal activity of final canal rinse with either three concentrations of sodium hypochlorite (naocl) (0.5, 2.6 and 6%), two concentrations of chlorhexidine (chx) (2% and 0.2%), mtad, tetraclean, hypoclean and chlor-xtra on candida albicans (c. albicans ) in a human tooth model. methods and materials: two hundred and thirty f...

AIM To specifically investigate the effect of endodontic irrigants at their clinical concentration on matrix polysaccharides of cultured biofilms. METHODOLOGY Saccharolytic effects of 3% H2 O2 , 2% chlorhexidine (CHX), 17% EDTA, 5% NaOCl and 0.9% saline (control) were tested using agarose (α 1-3 and β 1-4 glycosidic bonds) blocks (n = 3) in a weight assay. The irrigants were also applied to t...

Background and Aim: To compare time, concentration and temperature dependent antimicrobial activity of sodium hypochlorite (NaOCl) against Enterococcus faecalis (E. faecalis). Materials and Methods: A total of 144 antibiotic discs were infected by E. faecalis; 6 antibiotic discs served as negative controls. Discs were further divided into 12 subgroups according to 2 contact times (1and 5min) an...
