Introduction: The aim of this study was to evaluate the sealing ability of Bioactive glass (BG) and Bioactive glass-Hydroxyapatite (BG-HA) in comparison to Mineral Trioxide Aggregate (MTA). Methods: The sealing ability of Bioactive glass and Bioactive glass-hydroxyapatite mixed with glass ionomer cement and Mineral Trioxide Aggregate used as retrograde filling material was assessed by bacterial...

Mineral trioxide aggregate (MTA) has been recommended for various uses in endodontics. To understand the effects of MTA on alveolar bone, we examined whether MTA induces osteoblastic differentiation using MC3T3-E1 cells. MTA enhanced mineralization concomitant with alkaline phosphatase activity in a dose- and time-dependent manner. MTA increased production of collagens (Type I and Type III) and...

mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. molten sulfur reacted with olefinic additive, at 130-140 ºc, and then mixed with preheated filler and aggregates. sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 % filler and 58 % ...

introduction: the aim of this in vitro study was to evaluate the effect of various irrigants on the push-out bond strength of calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta). methods and materials: a total of 140 dentin disks with a thickness of 1.5±0.2 mm and lumen size of 1.3 mm, were randomly divided into 12 groups ( n =10) and 4 control groups ( n =5). the lumen o...

introduction: the aim of this in vitro study was to evaluate the tooth discoloration induced by calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta). methods and materials: forty five endodontically treated human maxillary central incisors were selected and divided into three groups ( n =15) after removing the coronal 3 mm of the obturating materials. in the mta group, whi...

introduction : the aim of this quantitative systematic review/meta-analysis was to compare the treatment outcomes of mineral trioxide aggregate (mta) and calcium hydroxide (ch) in pulpotomy of human primary molars. the focused pico question was “in case of pulp exposure in vital primary molars, how does mta pulpotomy compare to ch in terms of clinical/radiographic success?” methods and material...

introduction : this in vitro study was designed to evaluate the effect of smear layer removal on push-out bond strength of white mineral trioxide aggregate (wmta) and calcium-enriched mixture cement (cem). materials and methods: dentin discs with 3 mm thicknesses were divided into 4 groups ( n =15): group 1: irrigation of the canal with normal saline and filling with wmta; group 2: irrigation w...

introduction : the aim of this in vitro study was to evaluate the effect of smear layer on the push-out bond strength of white mineral trioxide aggregate (wmta) with and without disodium hydrogen phosphate (na 2 hpo 4 ). materials and methods: dentin discs with standard cavities were obtained from extracted human single-rooted teeth and divided to 4 groups ( n =15) according to the irrigation r...

objective: one of the principle purposes of root canal obturation is to obtain hermetic sealing of the root canal system. according to the development of technology, many materials are now used in root canal filling. an in vitro dye leakage study was performed to evaluate the apical sealability of white-colored mineral trioxide aggregate (wmta) and gray-colored portland cement (gpc) when used a...
