Background. This in vitro study aimed to compare the antibacterial effect of different concentrations of sodium hypochlorite on elimination of Enterococcus faecalis from root canal systems of primary teeth with or without a passive sonic irrigation system (EndoActivator). Methods. The root canals of 120 extracted single-rooted primary incisors were prepared using the crown-down technique. The t...

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 ...

2.1 Relationship between Oxidizing Power of Chlorine and Sodium Hypochlorite Many consumers are currently replacing chlorine with sodium hypochlorite as the oxidizing agent. In order to calculate how much sodium hypochlorite is required to replace the oxidizing power of chlorine, the following example is provided. If sodium hypochlorite is used to oxidize iodide in a solution of acetic acid, th...

OBJECTIVES This study aimed to evaluate the capacity of 2% chlorhexidine gel associated with 8% papain gel in comparison with 5.25% sodium hypochlorite in bovine pulp tissue dissolution. MATERIALS AND METHODS Ninety bovine pulps of standardized sizes were used and fragmented into 5-mm sizes. The fragments were removed from the root middle third region. They were divided into 6 experimental gr...

Background and Aim: Hepatitis B virus (HBV) is an important infectious agent in denti-stry necessitating the use of disinfectants to prevent its transmission. This study compared the efficacy of 2/100 sodium hypochlorite disinfectants prepared from 5% solution manufactured by four different manufacturers namely Ashimashi, Paknaz, Vitex and Active for disinfection of surfaces infected with HBV. ...

The purpose of this in vitro study was to compare the efficacy of 24% ethylenediaminetetraacetic acid (EDTA) gel and 17% EDTA solution in cleaning dentine walls after root canal instrumentation. Thirty human canine teeth were divided into three groups of 10 teeth each. In Group 1, 1% sodium hypochlorite was used as the irrigating solution; in Group 2, 1% sodium hypochlorite was used with 17% ED...

abstract       background and aim: dimensional changes of the impression materials after disinfection is a serious problem in dentistry which could fail the treatment. the aim of this study is to determine the effect of three disinfectants:2% deconex,5.25% sodium hypochlorite and nanosil d2 ,on dimensional changes of bayer alginate.       materials and methods: this experimental study was condu...

Background. The aim of the present study was to evaluate the effect of Corega and 2.5% sodium hypochlorite cleansing agents on the shear and tensile bond strengths of GC soft liner to denture base. Methods. A total of 144 samples (72 samples for tensile and 72 for shear bond strength evaluations) were prepared. The samples in each group were subdivided into three subgroups in terms of the clean...

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...
