Objective: To evaluate the cytotoxicity and antibacterial effect of bleached turmeric hydro-alcoholic extractcompared to sodium hypochlorite as an endodontic irrigant. Material Methods: Cytotoxicity was evaluatedon human skin fibroblasts using MTT assay. The irrigants were tested at 1, 5- 15-minutes time intervals. Aftercontact time, solution added well plates incubated. After incubation period...

background and aims. increasing the temperature of sodium hypochlorite (naocl) enhances its dissolution and antibacterial properties. however, the high resistance of multi-species biofilms could restrict the effect of the solution regardless of its temperature, enabling the long-term recovery of the surviving bacteria. the aim of this study was to investigate if the increase of temperature of n...

introduction: this in vitro study compared the antibacterial efficacy of 2.5% sodium hypochlorite gel and 2.5% and 5.25% sodium hypochlorite solutions on enterococcus faecalis ( e. faecalis ) biofilm. methods and materials: the root canals of 60 extracted human single-rooted teeth were contaminated with e. faecalis and incubated for 6 weeks. the samples were randomly assigned to three experimen...

introduction: sodium hypochlorite (naocl) is an effective antimicrobial irrigant, however its toxic effects and deterrent odor are not ideal. carvacrol is an edible plant extract with anti-inflammatory and anti-bacterial properties that is effective against enterococcus ( e ) faecalis . the aim of this study was to evaluate carvacrol's antibacterial efficacy against e. faecalis bacteria as a fi...

Introduction: Sodium hypochlorite is a solution used in endodontic treatment, and if an accidental apical extrusion occurs, serious complications may affect soft tissue. Objective: The aim of this article is to present a case of apical extrusion of sodium hypochlorite (NaOCl) during root canal system instrumentation. Case report: A 28-year-old woman sought a local dental service for root canal ...

A spectrofluorimetric method for the determination of paracetamol is presented, based on the oxidation of the analyte to give the fluorophore 2,2'-dihydroxy-5,5'-diacetyldiaminebiphenyl. Sodium hypochlorite was used as an oxidizing reagent and the optimum pH was found to be 10.0 (sodium carbonate-boric acid buffer solution). The linear concentration range of application was 0.1-100.0 micrograms...

A 12-year-old girl, with a previous history of bronchial reaction and contact dermatitis to sodium hypochlorite, was referred for root canal treatment. Complete immunologic evaluation revealed a mild hypersensitivity condition, as it was assessed by the RAST investigation to different allergens and the DTH reactivity expressed though migration inhibition test. The absence of a serious immunolog...

sodium hypochlorite has been used for disinfecting of cryptosporidium in some contaminated environments by this parasite and also in laboratory works it has been used for the purification of the parasite from bacteria and as a treatment for facilitating of releasing the sporozoites of cryptosporidium (excystation). the excystation is a critical stage of life cycle of the parasite. the purpose o...
