introduction: biocompatibility and antimicrobial activity of endodontic materials are of utmost importance. considering the extensive applications of mineral trioxide aggregate (mta) in dentistry and antimicrobial properties of silver nanoparticles, this study aimed to evaluate the subcutaneous inflammatory reaction of rat connective tissues to white mta with and without nanosilver (ns) particl...

Carrier and syringe-type devices are currently used to deliver mineral trioxide aggregate as a root-end filling material. In certain surgical situations these devices may be too difficult to use because of the location of the surgical site and the small size of the root-end preparation. This paper describes a new technique to overcome these difficulties by the formation and delivery of mineral ...

objective: the purpose of this study was to investigate the histological response to delib-erate perforation repaired using amalgam or mta either immediately or with delay on cats’ molars. materials and methods: twenty-eight molar teeth from four cats were used in this ex-perimental randomized study. after preparing the access cavity, the floor of pulp cham-bers were deliberately perforated wit...

introduction: the aim of this study was to evaluate the effect of adding propylene glycol (pg) to mineral trioxide aggregate (mta) liquid with volume ratio of 20% on the compressive strength (cs) of mta in two time periods (4 and 21 days) after mixing. methods and materials: four groups of steel cylinders ( n =15) with an internal diameter of 3 and a height of 6 mm were prepared and mta (groups...

internal resorption is rare in permanent teeth. treatment is usually performed through warm gutta-percha technique. if the resorptive process perforates the root, treatment may be more difficult and is usually performed via surgical approach. non-surgical repair of a perforating internal root resorption with mta was conducted in this case. before repairing the resorption, a master gutta-percha ...

introduction: the aim of this study was to compare the cytotoxicity of proroot mta (pmta), root mta (rmta) and portland cement (pc) on human gingival fibroblasts (hgfs). materials and methods: the extracts of the test materials were placed close to human gingival fibroblasts (hgfs) within 96-well plates. cellular viability was assessed using mtt assay in different intervals (freshly mixed, 4, 2...

The aim of this study was to compare the effectiveness of white mineral trioxide aggregate and gray mineral trioxide aggregate with different thicknesses and light curing glass ionomer cement when used as a barrier material in intracoronal bleaching procedures. In this study, 130 freshly extracted, caries free human permanent single rooted maxillary canine teeth were used. The teeth were random...

immediate restoration after vital pulp therapy is essential in order to create and maintain effective coronal seal.the aim of this study was to evaluate the shear bond strength of recently used pulp capping materials: white mineral trioxide aggregate (mta), and calcium enriched mixture cement (cem) to composite resin with the use of etch-and-rinse and self-etch adhesive systems and compare them...

background: fungi may play a key part in periradicular diseases. the aim of this study was to evaluate and compare the antifungal properties of two root-end filling materials, proroot mineral trioxide aggregate (mta) and mta-angelus, against candida albicans using tube-dilution test. materials and methods: the antifungal properties of proroot mta and mta-angelus against c. albicans was assessed...
