introduction: the purpose of this in-vitro study was to investigate the influence of the remaining calcium hydroxide (ch) as an intracanal dressing on the apical sealing ability of three endodontic sealers. materials and methods: sixty-six single and straight canals of recently extracted human permanent maxillary central incisors were used. all canals were prepared and sixty of them were random...

introduction: the ideal endodontic treatment for the teeth with in complete root-ends and necrotic pulps may involve the use of material which forms an immediate apical barrier instead of long term calcium hydroxide therapy. such procedure may lead us to a single appointment endodontic treatment. the purpose of the present study was to evaluate clinical and radiographic success rate in necrotic...

objective : application of sodium ascorbate as an antioxidant and calcium hydroxide as a buffering agent following intracoronal bleaching has been recommended. the aim of this study was to investigate the effect of using the mentioned materials on shear bond strength of composite resin to the bleached dentin. materials and methods: in this in vitro investigation, sixty human sound premolars wer...

The solubility of disodium terephthalate in aqueous sodium hydroxide and hydroxide–ethylene glycol mixtures was determined experimentally by temperature analysis, gravimetry titration. experimental results were compared with existing literature data the phase diagrams from −25 to 70 °C. has no considerable dependence on temperature. freezing points solutions vary composition like any other solu...
