INTRODUCTION The aim of the present investigation was to compare the efficacy of mineral trioxide aggregate (MTA) and 0.2% chlorhexidine (CHX) mixture to pure MTA, as a pulp capping material. METHODS AND MATERIALS The pulp of 24 lateral incisors and canines from four dogs were exposed and capped either with MTA or MTA+0.2% CHX. After 2 months the animals were sacrificed and the teeth were pre...

OBJECTIVE To characterize the hydration products of white mineral trioxide aggregate (MTA). METHODOLOGY Mineral trioxide aggregate, white Portland cement and bismuth oxide were evaluated using X-ray diffraction (XRD) analysis and Rietveld XRD. The cements were tested un-hydrated and after hydration and curing for 30 days at 37 degrees C. Analysis of hydrated cement leachate was performed week...

background: to evaluate and compare the efficacy of mineral trioxide aggregate (mta) and traditionally used calcium hydroxide (ca(oh)2) in inducing root end formation of immature roots of traumatized young permanent anterior teeth. materials and methods: the study was carried out on 22 nonvital, immature permanent maxillary incisors. samples were allotted into two groups – group i mta and group...

PURPOSE The purpose of this study was to compare mineral trioxide aggregate (MTA) with calcium hydroxide (Ca(OH)2) clinically and radiographically as a pulpotomy agent in immature permanent teeth (apexogenesis). METHODS Fifteen children, each with at least 2 immature permanent teeth requiring pulpotomy (apexogenesis), were selected for this study. All selected teeth were evenly divided into 2...

Background and Aim: The use of ceramics has a long history. A new category of these materials was used in medicine in 1960 introduced as bioceramics. Biocompatibility, osteoinductivity and sealing ability are among the most favorable characteristics of endodontic bioceramics. Introduction of mineral trioxide aggregate (MTA) revolutionized endodontics and this new era is progressively growing. ...

OBJECTIVE Several studies reported the local tissue reaction caused by mineral aggregate-based cements. However, few studies have investigated the systemic effects promoted by these cements on liver and kidney when directly applied to connective tissue. The purpose of this in vivo study was to investigate the systemic effect of mineral aggregate-based cements on the livers and kidneys of rats. ...

Introduction: In teeth with incomplete rhizogenesis, the canal is frustoconical and broad, foramen absent. The disinfection obturation protocol must be adapted to keep treatment within root limits. Mineral Trioxide Aggregate (MTA) performs an apexification by creating a hard tissue barrier cement deposits, it not toxic periradicular tissues. Hypoplasia quantitative enamel defect caused heredita...

PURPOSE The aim of this study was to compare mineral trioxide aggregate (MTA) with calcium hydroxide [Ca(OH)2] clinically and radiographically as materials used to induce root-end closure in necrotic permanent teeth with immature apices (apexification). METHODS Fifteen children, each with at least 2 necrotic permanent teeth requiring root-end closure (apexification), were selected for this st...
