abstract aims: chemical precipitation is a simple, efficient, and cost-effective method for eliminating heavy metals found in landfill leachate. the aim of the present study was to compare the efficacy rates of cadmium removal with the coagulants like poly aluminum chloride and lime using chemical precipitation method. materials & methods: in this experimental study, the raw studied samples wer...
calcium hydroxide is the most widely used intracanal medicament in endodontics, which should be removed prior to permanent root canal filling to minimize its intervention with the bonding of endodontic sealers. this ex-vivo study aimed to evaluate the effect of pretreatment with calcium hydroxide on the bond strength of resilon/epiphany self etch (se) to the radicular dentin after removing the ...
This study was designed to determine the effects of an aluminum hydroxide antacid and a calcium carbonate antacid on the bioavailability of ciprofloxacin (Cipro). Cipro (750 mg) was administered orally to 12 healthy volunteers in a three-way randomized crossover design. The three treatments included Cipro alone, four 850-mg calcium carbonate tablets taken 5 min before Cipro, and three 600-mg al...
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...

Several different techniques for placing calcium hydroxide into root canals have been proposed, such as amalgam carriers, vertical pluggers, McSpadden compactors, Lentulo drills, files and special syringes. Because correct filling of the root canal is necessary for calcium hydroxide paste to act effectively, the aim of this research was to study different techniques of root canal filling with c...
Currently calcium hydroxide is often used as an intra-canal medication during root canal treatment. It has a pH of approximately 12.5, and it has antimicrobial activity, tissue-dissolving ability, inhibits tooth resorption and induces repair by hard tissue formation. It has been promoted for intra-canal placement for various endodontic conditions, including apexification, apexogenesis, after tr...
We present 2 cases of intra-arterial injection of endodontic calcium hydroxide via the root canal system of molar teeth. Nonsetting calcium hydroxide paste was used as a temporary dressing during endodontic treatment and in both cases delivered via an injectable syringe technique. Retrograde flow of the calcium hydroxide occurred along the artery until its origin where orthograde flow continued...
