The long-term success of root canal treatment requires the prevention bacterial leakage between walls and obturation. In this study, we compared Enterococcus faecalis in thirty single-rooted mandibular premolars divided into three groups. roots two experimental groups were obturated using a single-cone obturation technique with different bio-ceramic sealers (MTA Fillapex CeraSeal) while convent...

A prospective in vivo investigation was conducted to determine radiographic and clinical factors associated with contemporary nonsurgical endodontic retreatments. Approximately 1,100 failing endodontically treated teeth were screened to determine an appropriate treatment plan. Using magnification, 337 consecutive retreatment cases were evaluated and treated. The vast majority of the retreated c...

Mineral trioxide aggregate (MTA) has emerged as a reliable bioactive material with extended applications in endodontics that include the obturation of the root canal space. This article examines the literature supporting MTA as a canal filling material, suggests methods for its delivery and placement, and presents clinical cases that demonstrate its effectiveness in resolving apical periodontit...

BACKGROUND Although prosthetic obturation is the "gold standard" for restoration of hard-palate defects, obturators can be problematic. We present 10 cases of palatal reconstruction with the radial forearm free flap and compare patient satisfaction with defect-matched patients rehabilitated with prosthetic obturation. METHODS Twelve patients who underwent radial forearm free flap (RFFF) recon...

Two surgical cases are presented in which retrograde instrumentation of the root canal was accomplished with sonic or ultrasonic instruments. The canals were obturated from a retrograde direction with thermoplasticized gutta-percha and root canal sealer. Success of these treatment approaches is attributed to thorough debridement and satisfactory obturation with equipment only recently available...
