OBJECTIVES The purpose of this study was to investigate the sealing ability of root-end filling materials such as mineral trioxide aggregate (MTA), Portland cement, and bioaggregate (BA) after irrigation with different solutions. MATERIALS AND METHODS We examined 130 human maxillar central teeth. After cutting the teeth at the cementoenamel junction, the root canals were expanded using nickel...
Mineral trioxide aggregate (MTA) is a bioactive endodontic cement (BEC) mainly comprised of calcium and silicate elements. The cement was introduced by Torabinejad in the 1990s and has been approved by the Food and Drug Administration to be used in the United States in 1997. A number of new BECs have also been introduced to the market, including BioAggregate, Biodentine, BioRoot RCS, calcium-en...
Background: Aim of the study was to evaluate sealing ability of five different root end filling materials by dye penetration method. Materials and Methods: About 100 extracted maxillary central incisors were sectioned at Cementoenamel junction. Access cavities were prepared, instrumented chemo-mechanically, and obturated with laterally condensed gutta-percha and AH Plus sealer. Access cavities ...
