introduction: microleakage is of the causes of endodontic treatment failure. the aim of this in vitro study, was to compare the microleakage of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement apical plugs in three environments. methods and materials: a total of 130 human extracted single rooted teeth were collected. after decoronation, preparation of the root canal sp...

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...

background and aims: in various clinical situations, mineral trioxide aggregate (mta) may come into direct contact with blood. the aim of the present study was to evaluate the effect of exposure to blood on marginal adaptation and surface microstructure of mta. materials and methods: thirty extracted human single-rooted teeth were used in this study. standard root canal treatment was carried ou...

background and aims. it is important to evaluate the effects of endodontic materials on tooth structures to avoid endodontic treatment failure. the aim of the present study was to investigate the effect of mineral trioxide aggregates (mta) and portland cement (pc) on fracture resistance of dentin. materials and methods. thirty-six freshly extracted human single-rooted premolar teeth were select...

the aim of this study was to compare the effect of an acidic environment on dislocation resistance (push-out bond strength) of endosequence root repair material (errm putty and errm paste), a new bioceramic-based material, to that of mineral tri-oxide aggregate (mta).one-hundred twenty root dentin slices with standardized canal spaces were divided into 6 groups (n = 20 each) and filled with too...

root perforations are an undesired complication of endodontic treatment which result in loss of integrity of the root, and adversely affect the prognosis of the treatment. recently, iranian mineral trioxide aggregate (root mta) has been introduced as an ideal material for perforation repair. in this article a successful repair of strip root perforation of mandibular molar using root mta is pres...

introduction: the materials used for root-end filling and perforation repair are in direct contact with live tissues e.g. bone and connective tissue; their effects however, are uncertain. the aim of this ex vivo study was to evaluate the osteoblastic secretory activity adjacent to gray and white mineral trioxide aggregate (mta) and intermediate restorative material (irm). materials & methods: t...
