marginal adaptation of new bioceramic materials and mineral trioxide aggregate: a scanning electron microscopy study
introduction: this study aimed to compare the marginal adaptation of new bioceramic materials, endosequence root repair material (errm putty and errm paste), to that of mineral trioxide aggregate (mta) as root-end filling materials. materials and methods: thirty-six extracted human single-rooted teeth were prepared and obturated with gutta-percha and ah-26 sealer. the roots were resected 3 mm f...
متن کاملRoot perforations treatment using mineral trioxide aggregate and Portland cements.
PURPOSE Clinical, radiological and histological evaluation of root perforations treated with mineral trioxide aggregate (MTA) or Portland cements, and calcium sulfate barrier. METHODS One molar and 11 premolar teeth of a male mongrel dog received endodontic treatment and furcations were perforated with a high-speed round bur and treated with a calcium sulfate barrier. MTA, Portland cement typ...
متن کاملRemoval of White Mineral Trioxide Aggregate Cement: A Promising Approach
Removal of MTA from dentin by applying 37% hydrochloric acid (HCl) to reduce microhardness and push-out bond strength. Forty dentin slices were filled with WMTA and divided into two groups (n = 20). Ten slices remained untreated while others were exposed to either HCl or phosphate buffer saline (PBS) and all samples were subjected to pushout test. The mode of bond failures was determined by SEM...
متن کاملHealing of Root Perforations Treated with Mineral Trioxide Aggregate (mta) and Portland Cement
Fourteen root perforations were performed for microscopic evaluation of the repair of interradicular tissue in dogs' teeth. These perforations were accomplished at low-speed with a STP 58 bur at the cervical third of the mesial root toward the furcation under irrigation with saline solution, followed by immediate sealing with ProRoot MTA, MTA-Angelus and white Portland cement. The dogs were kil...
متن کاملSetting expansion of gray and white mineral trioxide aggregate and Portland cement.
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...
