AIM To evaluate the antibacterial activity of sodium hypochlorite (NaOCl) and chlorhexidine (CHX) alone or associated with cetrimide (CTR), and QMiX against biofilm and planktonic Enterococcus faecalis (E. faecalis) [American type culture collection (ATCC) 29212]. MATERIALS AND METHODS The solutions 2.5% NaOCl, 2.5% NaOCl + 0.2% CTR, 2% CHX, 2% CHX + 0.2% CTR, 0.2% CTR, and QMiX were evaluate...

BACKGROUND The aim of this study was to investigate the effect of wettability enhancement for 17% EDTA, 2.5% sodium hypochlorite and 7% maleic acid solutions on push out bond strength of gutta percha /AH Plus to root dentin. MATERIAL AND METHODS One hundred and eight extracted single rooted human lower premolars were instrumented up to Protaper Universal F5 then irrigated with 3ml of 2.5% NaO...

Root canal irrigants play a significant role in elimination of the microorganisms, tissue remnants, and removal of the debris and smear layer. No single solution is able to fulfill all these actions completely; therefore, a combination of irrigants may be required. The aim of this investigation was to review the agonistic and antagonistic interactions between chlorhexidine (CHX) and other irrig...

AIM This study was undertaken to determine the antimicrobial effect of various endodontic irrigants against six selected microorganisms. METHODOLOGY Staphylococcus aureus, Enterococcus faecalis, Streptococcus salivarius, Str. pyogenes, Escherichia coli and Candida albicans were included in the study. Pre-sterilized Whatman paper discs, 6 mm in diameter and soaked with the test solution, were ...

Introduction: Endocyn, a super-oxidized water-based irrigation solution, has been reported to be non-toxic against mammalian cells, yet highly efficacious against bacteria; however, its effect against fungi and fungal biofilms remain unknown. This study evaluated the antifungal efficacy of Endocyn compared to sodium hypochlorite (NaOCl) and chlorhexidine (CHX). Methods: An in vitro biofilm syst...

Abstract Background Given the favorable antimicrobial properties of zinc oxide (ZnONPs), standard silver (AgNPs), and imidazolium-based (Im-AgNPs) nanoparticles, this study aimed to evaluate their influence on microhardness root canal dentin. Methods In experimental study, 40 mandibular premolars were decoronated at cementoenamel junction longitudinally sectioned into halves create 80 specimens...

Adequate removal of the previous filling material may be pivotal to a favorable outcome root canal retreatment teeth with post-treatment periodontitis in order permit access irrigants and medicaments persistent bacteria. However, even recent technological advances, including introduction specially designed instruments, no technique has been shown predictably promote complete removal. Supplement...
