background and aims. the aim of this study was to compare the biocompatibility of calcium-enriched mixture ce-ment (cem), composite resin and nano-particled mineral trioxide aggregate (np-mta) using human gingival fibroblasts. materials and methods. a comparative in vitro cell culture study was carried out using 60 single-rooted teeth which were assigned to the following four groups: 1) untreat...

conclusions this study suggested that chlorhexidine had no negative effect on the bond strengths of mta-treated dentin. results there were no statistically significant differences between all the experimental groups. the mode of bond failure was predominantly mixed for distilled water groups and cohesive for chx groups. materials and methods sixty dentin disks with a thickness of 1.5 ± 0.2 mm a...

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...

The purpose of this study was to compare the ability of different thicknesses of mineral trioxide aggregate (MTA) to prevent apical leakage through the use of a protein-dye complex with Coomassie Brilliant Blue G. Sixty-four teeth were divided into 4 groups, then filled with MTA to depths of 1, 2, 3, or 4 mm. Two teeth served as the positive controls. Another 2 teeth served as the negative cont...

"It has been said that Mineral Trioxide Aggregate is driving an endodontic revolution. Discuss this statement considering the biological and clinical attributes of this innovative material."

External inflammatory root resorption (EIR) represents a challenge in endodontic practice. EIR commonly occurs after dental trauma that results in periodontal ligament injury, pulp necrosis and subsequent infection.  Treatment of EIR is based on disinfecting the root canal system through chemomechanical procedures and then filling it with calcium hydroxide or triple antibiotic paste. Dental tra...

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...
