The purpose of this in vitro study was to compare the apical sealing ability of mineral trioxide aggregate and glass ionomer cement by a dye penetration test. It was carried out at Queen Marry and Westfield College, University of London during 2010-2011 session. Time duration was 6 months. A total of 16 samples of elephant tusk dentine (ivory) were prepared and finished for dye penetration test...

Objective: The Purpose of this investigation was to assess the effectiveness of Mineral Trioxide Aggregate in providing an apical seal in comparison with High Copper Silver Amalgam, Conventional Glass Ionomer Cement Type 2, and Glass Cermet cement by using a dye penetration method. Methods: The root canals of seventy extracted teeth were instrumented and obturated with gutta-percha. Each tooth ...

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...

One possible reason for the sealing ability of mineral trioxide aggregate (MTA) is its slight expansion upon setting. Both gray mineral trioxide aggregate (GMTA) and white mineral trioxide aggregate (WMTA) are composed of approximately 75% Portland cement (PC). WMTA differs from GMTA in its lower content of tetracalcium aluminoferrite. This difference in composition may affect setting expansion...

this case report describes the treatment of two immature maxillary central incisors in a 7- year-old female patient. she suffered complicated crown fracture because of trauma, and the root formation was incomplete. white mineral trioxide aggregate (mta) was selected as the pulp-capping material after cervical pulpotomy to preserve the pulp tissue vitality and achieve maturogenesis. follow-up ev...

o bjectives: the aim of this study was to evaluate marginal adaptation of mineral trioxide aggregate (mta), calcium enriched mixture (cem) cement, biodentine and bioaggregate in presence of normal saline and human blood. materials and methods: in this in-vitro experimental study, 80 extracted single-rooted human teeth were instrumented and filled with gutta-percha. after resect- ing the root-en...

introduction: the aim of this study was to evaluate the effects of remnant root canal medicament, calcium hydroxide on the short and long term sealing ability of mineral trioxide aggregate (mta) apical barrier. materials & methods: fifty single-rooted teeth were prepared and apical resorptions were made using sulfuric acid. the teeth were allocated into two experimental groups and two control g...

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...
