Pathological changes in pulp and periapical tissues are addressed by endodontic treatment. The material used in this treatment must be biocompatible. The aim of this study is to compare the skin reaction of Calcium Enriched Mixture (CEM) and Mineral Trioxide Aggregate (MTA) produced in Iran on rabbit. Sixteen male newzeland albino rabbits weighting 2 kg were used. The animals back hair was sha...

background and aims: we aimed to assess the bond strength of composite resin to three pulp capping biomaterials; proroot mineral trioxide aggregate (pmta), root mta (rmta) and calcium enriched mixture (cem), using three bonding systems [a total etch (single bond) and two self-etch systems (protect bond and se bond)]. materials and methods: ninety acrylic moulds containing a 6×2 mm hole were div...

PURPOSE To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material. METHODS Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated with MTA as the root-end filling materia...

background and aim(s): this in vitro study compared the effects of mineral trioxide aggregate (mta), calcium enriched mixture (cem) cement, biodentine (bd) and octacalcium phosphate (ocp) on the viability of human gingival fibroblasts (hgfs). material and methods: after completion of the setting time of understudy materials, fibroblasts were placed in 24-well insert plates and 1mg of the unders...

OBJECTIVE This study compared the chemical constitution, radiopacity, and biocompatibility of Portland cement containing bismuth oxide (experimental cement) with those of Portland cement and mineral trioxide aggregate (MTA). STUDY DESIGN The chemical constitution of materials was determined by scanning electron microscopy and energy-dispersive X-ray analysis. The radiopacity of the materials ...

OBJECTIVE To compare the fracture resistance of simulated immature teeth filled with an apical barrier of mineral trioxide aggregate (MTA), Biodentine, and calcium-enriched mixture (CEM). MATERIALS AND METHODS Fifty-two single-rooted human maxillary central incisors were used. For standardization, the teeth were sectioned 6 mm above and 9 mm below the cementoenamel junction to simulate immatu...

OBJECTIVE To characterize the hydration products of white mineral trioxide aggregate (MTA). METHODOLOGY Mineral trioxide aggregate, white Portland cement and bismuth oxide were evaluated using X-ray diffraction (XRD) analysis and Rietveld XRD. The cements were tested un-hydrated and after hydration and curing for 30 days at 37 degrees C. Analysis of hydrated cement leachate was performed week...

OBJECTIVE The presence of arsenic in various types of mineral trioxide aggregate (MTA) and Portland cements were evaluated to verify if they comply with the ISO-recommended limit for water-based cements of 2 mg arsenic/kg material. STUDY DESIGN An amount of 5 mL of hydrochloric acid was added to 2 g each of MTA and Portland cement to be analyzed. After 15 minutes, the material was filtered an...
