Sodium hypochlorite is often used as an irrigation solution during routine endodontic treatment. Before recementation of a post-retained crown on the upper left lateral incisor, the root canal was irrigated with sodium hypochlorite. There was no root filling in the root canal, and the apex was open after an earlier apicoectomy. Sudden pain with swelling of the left face side occurred during roo...

Granular activated carbon (GAC), in the presence of dilute aqueous hypochlorite solutions typical of those used in water treatment, was converted to a reagent capable of carrying out free-radical coupling reactions and other oxidations of dilute aqueous solutions of phenols. The products included biphenyls with chlorine and hydroxyl substitution (hydroxylated polychlorinated biphenyls). For exa...

The ETP sludge of a hypochlorite manufacturing industry can be a potent pollutant of an aquatic environment. The hyposludge is highly alkaline with high TDS. It is milky white with sodium hypochlorite as a major constituent. The present work attempts to identify micro algae which can tolerate and grow in the hyposludge, Preliminary laboratory screening revealed that Chlorococcum humicola and Ch...

Water hyacinth ( Eichhornia crassipes ) is one of the potential feedstocks for bioethanol production due to their higher cellulose content. It needs optimization pretreatment remove lignin and release hemicellulose from lignocellulosic complex. Pretreatment was done using sulfuric acid, sodium hydroxide, calcium hypochlorite as soaking agents. Experiment carried out at 121 °C 15 minutes. with 1...

Failure of seed sterilization methods and breakdown in sterile technique can result in catabolism of thymidine by microorganisms during seedling incubation in radioisotope. The effectiveness of some sterilizing agents was monitored by microbiological methods and by thin layer chromatography for the presence of thymidine degradation products. Sodium hypochlorite and ethylene oxide each sterilize...

Hypomineralized enamel defects frequently are manifest as a mottled-white appearance and can be associated with variable degrees of discrete yellow-brown intrinsic staining. Numerous treatment approaches have been proposed, ranging from bleaching to enamel reduction to restorative techniques. Bleaching of hypomineralized enamel lesions, using 1 to 2 applications (10 to 15 minutes each) of 5% so...

introduction: formocresol is widely used in primary teeth pulpotomies; however it is known to have several side effects. the purpose of this study was to assess pulpal changes of primary teeth pulps after pulpotomy with sodium hypochlorite and formocresol. materials and methods: in this randomized clinical trial, 22 teeth were selected. these teeth were randomly divided into 2 groups (formocres...

Fibrinogen, a major constituent of blood plasma, is highly susceptible to reaction with biological oxidants. It has been proposed that fibrinogen plays role in antioxidant defence, but oxidation also known disrupt normal clotting and implicated the pathology atherosclerosis. In present study, we show oxidant hypochlorite promotes formation soluble high molecular weight assemblies ≥40 × 106 Da, ...
