“…One of the important properties of MTA is its superior ability to resist leakage (15), which may be explained by its superior marginal adaptation (16). High alkalinity, due to the predominant presence of calcium hydroxide in the formulation of MTA after mixing with water, results in biologic properties similar to those of calcium hydroxide (17). Thus, it is hypothesized that MTA may be used to prevent or arrest tooth resorption.…”

Objectives: There is some evidence that the pH at the root surface is reduced by intracoronal placement of bleaching pastes, which is known to enhance osteoclastic activity. Therefore, it is recommended that a protective barrier be used over the canal filling to prevent leakage of bleaching agents. Glass-ionomer (GI) is commonly used as a coronal barrier before nonvital bleaching. Because mineral trioxide aggregate (MTA) creates high alkalinity after mixing with water, using MTA as a protective barrier over the canal filling may not only prevent leakage of bleaching agents and microorganisms, but may prevent cervical resorption. The aim of this study was to evaluate sealing ability of white mineral trioxide aggregate (WMTA) as a coronal barrier before nonvital bleaching. Study design: Root canals of one hundred thirty human maxillary incisors were instrumented and filled with gutta-percha without sealer. Gutta-percha was removed up to 3 mm below the cementoenamel junction (CEJ). The teeth were randomly divided into six experimental groups of 20 teeth each and two control groups of 5. In three experimental groups, WMTA was packed into the canal to the level of CEJ. In the remaining experimental groups, glass-ionomer (GI) was used as a coronal barrier. After a 24-hour incubation period, one of the following three bleaching agents was placed in the access cavity of each of the WMTA or GI groups. These three bleaching agents were 30% hydrogen peroxide, sodium perborate mixed with 30% hydrogen peroxide, and sodium perborate mixed with distilled water. The bleaching agents were replaced every 3 days for three times. In the positive controls, no Comparison of glass-ionomer and white mineral trioxide aggregate used as a coronal barrier e1018 coronal barrier was used. In the negative controls, all the tooth surfaces were covered by two layers of nail varnish. Microleakage was evaluated using protein leakage test. Statistical analyses were performed with the Kruskal-Wallis and Mann-Whitney tests.Results: The experimental groups showed minimum leakage which was not significantly more than tha in the negative controls. There was no statistically significant difference in leakage between the experimental groups (p<0.05).Conclusions: This study indicated that different bleaching agents have no effect on sealing ability of WMTA.

“…Tooth discoloration has been reported with the use of gray MTA in direct pulp capping 74) and therefore the use of white MTA has generally been recommended in the esthetic zone. However, tooth discoloration associated with white MTA was also described in case reports in endodontic treatments 75,76) . Tooth color change was reported to be induced by both gray and white MTA in vitro 77) .…”

“…Taken together, the antimicrobial activity of MTA may not be as strong as those of traditional calcium hydroxide-based cements and sealers 70) . In spite of its many positive properties, some disadvantages of MTA include long setting times, poor handling [71][72][73] , and coronal tooth discoloration [74][75][76][77] . Reported setting times have shown variations: 50 min 73) , less than 4 h 78) and 70 and 175 min for the initial and final setting times 79) , respectively.…”

Direct pulp-capping is a method for treating exposed vital pulp with dental material to facilitate the formation of reparative dentin and to maintain vital pulp. Two types of pulp-capping materials, calcium hydroxide and mineral trioxide aggregate, have been most commonly used in clinics, and an adhesive resin has been considered a promising capping material. However, until now, there has been no comprehensive review of these materials. Therefore, in this paper, the composition, working mechanisms and clinical outcome of these types of pulp-capping materials are reviewed.

“…Durante os anos 90 a Doxa AB finalizou a formulação do material em uma versão comercial do cimento aluminoso chamado de Doxadent ® , recebendo o selo CE no ano de 2000 e introduzido no mercado odontológico em outubro do mesmo ano [3]. Um cimento endodôntico a base de cimento de aluminato de cálcio (ECAC) também foi desenvolvido [4,5] visando preservar e ampliar as propriedades positivas e aplicações clínicas do material mais utilizado atualmente como um cimento reparador conhecido por MTA (mineral trioxide aggregate), além de superar as suas limitações dentre as quais se destacam a baixa resistência mecânica [6,7], escurecimento do dente ao longo do tempo, pega lenta e alto custo [8,9]. O aluminato de cálcio também tem sido estudado como um cimento reparador em ortopedia [10].…”

88Cerâmica 60 (2014) [88][89][90][91][92][93][94][95] INTRODUÇÃOOs cimentos de aluminato de cálcio constituem os agentes ligantes mais utilizados em aplicações refratárias industriais, devido principalmente a sua disponibilidade, baixo custo, capacidade de conferir alta resistência mecânica e resistência ao ataque por agentes agressivos, quando em uso [1,2].O cimento de aluminato de cálcio também tem sido utilizado na área da saúde. Sua aplicação iniciou-se no campo odontológico, onde em 1987, Hermansson desenvolveu um processo químico com o objetivo de criar um novo restaurador dental mais biocompatível do que a amalgama. No mesmo ano ele fundou a Doxa Certex AB, posteriormente Doxa AB, dando continuidade ao desenvolvimento do cimento aluminoso. A primeira patente foi depositada em 1990 como um material restaurador dental. Durante os anos 90 a Doxa AB finalizou a formulação do material em uma versão comercial do cimento aluminoso chamado de Doxadent ® , recebendo o selo CE no ano de 2000 e introduzido no mercado odontológico em outubro do mesmo ano [3].
