Evaluation of root canal obturation: a three-dimensional in vitro study.
The aim of the study was to measure percentage of volume of voids and gaps in root canals obturated with different obturation materials by using micro-computed tomography (micro-CT). Forty-eight single-rooted teeth were collected and decoronated, and root canals were prepared by using rotary files. The roots were randomly allocated into 4 groups, and each group was obturated by using cold later...

متن کاملEx-vivo Apical Seal Comparison of Root Canal Obturation Using MTA Fillapex Versus MTA Orthograde
Introduction: Mineral trioxide aggregate (MTA) as an alternative material to gutta-percha for obturation of root canal in special cases has several drawbacks. The purpose of this study was to compare the apical sealing ability of a new MTA-based sealer versus MTA. Materials and Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and randomly divided into 3...

Objective: Root canal obturation is an important step in endodontic therapy aiming at achieving a complete three-dimensional seal of the canal and preventing microleakage, reentry or growth of microorganisms in the root canal system. Several techniques and materials are available for root canal filling. Achieving an apical seal is among the most important characteristics of filling materials....
