o bjectives: the purpose of this experimental study was to compare the disinfection efficacy of sodium hypochlorite and peroxygenic acid (virkon) solutions for dental stone casts contaminated with microbial strains . materials and methods : a total of 960 spherical stone beads with a diameter of 10 mm were prepared and used as carriers of bacterial inoculums. they were individually inoculated b...

BACKGROUND The present study compared both the antiseptic efficacy of sodium hypochlorite against that of chlorhexidine gluconate in isopropyl alcohol and the substantive effect of chlorhexidine, povidone iodine, and sodium hypochlorite. METHODS This was a 2-step study that included volunteers. In step 1, 4 skin areas were tested for bacteria in colony-forming units (CFU): 2 were controls to ...

OBJECTIVE The goal of this study was to compare the dissolving potential of Dakin's solution with that of equivalent buffered and unbuffered sodium hypochlorite solutions on fresh and decayed tissues. In addition, the antimicrobial effect of Dakin's solution and equivalent unbuffered hypochlorite was tested. STUDY DESIGN Tissue specimens were obtained from freshly dissected pig palates. Unbuf...

AIM This case report describes a serious and life-threatening complication of the use of sodium hypochlorite as an irrigation solution in root canal therapy. SUMMARY This case report describes a hypochlorite accident that occurred in a healthy 42-year-old female who was undergoing routine root canal therapy for the lower right central incisor (tooth #41). After approximately 1 hour of irrigat...

materials and methods: eighty-four single rooted human teeth were randomly divided into 7 groups, 12 cases each, and canals were instrumented with mtwo rotary systems. 5.25% sodium hypochlorite, smear clear and 17% edta were used for irrigation of the canal during and/ or after instrumentation. after completion of instrumentation, all canals were dried with paper points and prepared to examine ...

introduction: effective debridement of the root canal system with chemical irrigants prior to obturation is the key to long-term success of endodontic therapy. the purpose of this study is to compare the antibacterial activity of 2.5% sodium hypochlorite (naocl) and 2% iodine potassium iodide (iki) solutions as intracanal disinfectant in infected root canals during one-visit endodontic treatmen...

background and aims. the aim of the present study was to compare 1.3% sodium hypochlorite (naocl) in mtad (mixture of tetracycline isomer, acid, and detergent) for the removal of the smear layer and induction of canal erosion. materials and methods. 38 maxillary incisors were divided in three experimental groups of 10 and two positive and negative control groups of each 4 teeth, and prepared us...

A wireless, passive, remote-query sensor for monitoring sodium hypochlorite (bleach) solutions is reported. The sensor is comprised of a magnetically-soft ferromagnetic ribbon, coated with a layer of polyurethane and alumina, having a large and nonlinear permeability that supports higher-order harmonics in response to a time varying magnetic field. The hypochlorite ions induce swelling in the c...

AIM To report the presentation and management of two cases with neurological complications secondary to the extrusion of sodium hypochlorite solution into the facial soft tissues during root canal treatment. SUMMARY The clinical features, with particular emphasis on nerve deficit following inadvertent extrusion of sodium hypochlorite, are discussed and its management highlighted. Early and ag...
