OBJECTIVE This study evaluated the effect of two different eugenol-based root canal sealers on the retention of prefabricated metal posts luted with adhesive resin cement. MATERIALS AND METHODS Thirty prefabricated ParaPosts randomly divided among three groups of 10 each were luted into extracted single-rooted teeth with adhesive resin cement. Two of the groups had been obturated with Gutta-P...

introduction: computed tomography (ct) and cone-beam ct (cbct) are valuable diagnostic aids for many clinical applications. this study was designed to compare the gray scale value (gsv) and hounsfield unit (hu) of selected dental materials and various hard tissues using ct or cbct. methods and materials: three samples of all test materials including amalgam (am), composite resin (cr), glass ion...

Objective To evaluate solubility and sealing ability of Mineral Trioxide Aggregate (MTA) and root-end filling materials. Material and Methods The materials evaluated were: MTA, Calcium Silicate Cement with zirconium oxide (CSC/ZrO2), and zinc oxide/eugenol (ZOE). Solubility test was performed according to ANSI/ADA. The difference between initial and final mass of the materials was analyzed afte...

Successful final restoration is important for the long term success of root canal treatment. A lack of adhesion in a final restoration could result in apical or coronal leakage that causes problems in the root canal treatment. Endodontically-treated teeth frequently require extensive restorations with post-core system. ABSTRACT The Influence of AH-26 and Zinc Oxide-Eugenol Root Canal Sealer on ...

Aim: To evaluate the resistance of union between a glass fiber post and radicular dentine after cleaning root with 17% EDTA filling different endodontic cements. Methods: Forty uniradicular bovine incisors were removed to obtain lengths 18 mm. Endodontic treatment was performed on all roots using cements (zinc oxide eugenol-based, OZE; cement based epoxy resin, AH) solutions (saline, SA or EDTA...
