objective: one of the principle purposes of root canal obturation is to obtain hermetic sealing of the root canal system. according to the development of technology, many materials are now used in root canal filling. an in vitro dye leakage study was performed to evaluate the apical sealability of white-colored mineral trioxide aggregate (wmta) and gray-colored portland cement (gpc) when used a...

OBJECTIVES The aim of this study was to evaluate the apical sealability of Fillapex®, endo-CPM-Sealer® and Sealapex®. MATERIAL AND METHODS Ninety-four freshly extracted single-rooted teeth were selected and decoronated. All teeth were radiographed to confirm the existence of a single and straight root canal, which was prepared using Protaper Universal and 2.5% sodium hypochlorite. The teeth w...

statement of problem: when a tooth is treated endodontically, there are several objectives, which must be met for the root canal therapy to be successful. one of those objectives is the complete obturation of the root canal system. purpose: the purpose of this study was to evaluate the apical sealability of the theramfil endodontic obturation technique and compared it with lateral condensation....

INTRODUCTION The purpose of this study was to compare the sealability of three different commercial types of mineral trioxide aggregate (MTA) and calcium enrichment mixture (CEM) cement as an experimental root-end filling material. MATERIALS AND METHODS Forty-six single rooted teeth were cleaned, shaped, and obturated. The apical 3 mm of each root was resected and root-end cavities with 3 mm ...

3 F a bstract he purpose of treating furcal perforation is to sea rtificial communication between the endodontic spa nd the periradicular tissue to prevent alveolar b esorption and damage to the periodontal ligame hese complications are not infrequent in cases urcal and/or old perforations, which show a w rognosis than fresh, small, coronal, and apical pe ations. Mineral trioxide aggregate (MTA...

The present investigations on sealability evaluation for tubing and casing premium connections depend the FEM with testing. This paper proposed a theoretical model to evaluate of sphere-type connection based make-up torque, which combines Hertz contact pressure von Mises yield criterion calculating elastic–plastic distribution sealing interface adopts gas obtained from Murtagian’s experimental ...

Several features make Java an attractive choice for scientific applications. In order to gauge the applicability of Java to Computational Fluid Dynamics (CFD), we have implemented the NAS Parallel Benchmarks in Java. The performance and sealability of the benchmarks point out the areas where improvement in Java compiler technology and in Java thread implementation would position Java closer to ...

Abstract In this experimental study, two different cementitious materials, including (i) a class of expansive cement currently used for plug and abandonment (P&A) operations (ii) non-cement-based naturally occurring rock, known as geopolymer, are selected to examine the hydraulic bond strength shear strength. Clean machined steel rusty corroded were represent casing. The test samples cured ...
