introduction: to evaluate the effects of using sodium hypochlorite irrigant on pull-out bond strength of self-etch and self-adhesive resin cements to dentin. methods: sixty intact premolars were decoronated and the root canals were prepared by step-back technique. the teeth were divided into two groups according to the irrigant used during root canal treatment: 5.25% sodium hypochlorite and nor...

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: sodium hypochlorite is found in bleaching agents used to cleaning dishes and bleach laundry. the ingestion of sodium hypochlorite causes acute corrosive esophagitis and gastritis. in establishing the diagnosis and therapeutic approach of acute corrosive poisonings, the upper endoscopy has great importance. the aim of this study was to determine predictive factors of gastrointestinal...

the purpose of the review was to assess the effect of root canal irrigants on dentin bonding. a pubmed-based search was conducted on the articles published from 1980 to 2016. a brief overview and reviewing the effect on dentin bonding of common root canal irrigation solutions such as sodium hypochlorite (naocl), chlorhexidine (chx), ethylenediaminetetraacetic acid (edta), mixture of a tetracycl...

the purpose of this study was to assess the in vitro effect of ascorbic acid on the antibacterial substantivity of tetraclean in bovine root dentin pretreated with sodium hypochlorite (naocl).eighty dentin tubes prepared from bovine incisor teeth were infected with enterococcus faecalis for 14 days. the specimens were divided into five groups as follows: tetraclean; 5.25% naocl/tetraclean; 5.25...

introduction: this study compared the efficacy of light-activated low-power laser, 2% chlorhexidine (chx) and 2.5% naocl in eliminating enterococcus faecalis ( e. faecalis) from the root canal system. methods and materials: the root canals of 60 maxillary central incisors were contaminated with e. faecalis and then the bacteria were incubated for 24 h. all the root canals were instrumented in a...

To evaluate disinfection methods for environments contaminated with bioterrorism-associated microorganism (Bacillus anthracis), we performed the following experiments. First, the sporicidal effects of sodium hypochlorite on spores of five bacterial species were evaluated. Bacillus atrophaeus was the most resistant to hypochlorite, followed in order by B. anthracis, Clostridium botulinum and Clo...
