Aim of the study is to compare quality apical seal offered by a zinc-eugenol and tricalcium-silicate-based sealer, both used with single-cone or continuous wave condensation technique. Forty central incisors were divided into four groups (n = 10), according two sealers obturation techniques under investigation, their outer surface was isolated nail varnish. After endodontic treatment, samples i...

The aim of this study was to evaluate the influence of eugenol-containing endodontic sealers and luting strategy on the pull-out bond strength of glass fiber posts to dentin. Sixty-four bovine incisors were randomly assigned into two groups of 32 specimens each for obturation procedure with gutta-percha only, or with Pulp Canal Sealer EWT Subsequently, the roots were prepared for the fiber post...

INTRODUCTION One of the key factors in successful endodontic therapy is to adequately fill the root canals. The aim of this in vitro study was to compare the quality of four different root canal obturation techniques: cold lateral condensation (CLC), warm vertical condensation (WVC), Obtura II (OII) and Gutta Flow (GF) by using micro-computed tomography (micro CT). MATERIALS AND METHODS A tot...

PURPOSE Clinical, radiological and histological evaluation of root perforations treated with mineral trioxide aggregate (MTA) or Portland cements, and calcium sulfate barrier. METHODS One molar and 11 premolar teeth of a male mongrel dog received endodontic treatment and furcations were perforated with a high-speed round bur and treated with a calcium sulfate barrier. MTA, Portland cement typ...

BACKGROUND Endodontic procedures such as root canal treatment would be at the risk of failure like other medical interventions due to any unsuitable conditions. This has a causative effect in making the procedure more complicated to resulting in weak prognosis finally. Technical errors such as ledge, perforation, obstruction, broken instrument, etc. make infection control too hard or impossible...

To perform successful endodontic therapy, it is important to know the anatomy and morphology of the root canal system. Peculiarities with possible anatomic variations may lead to failure due to insufficient instrumentation and inadequate three-dimensional obturation of the root canal system.[1,2] Accurate radiographic examination using different horizontal angles is crucial for the endodontist ...

statement of problem: failure of endodontic treatment is determined on the basis of radiographic findings and clinical signs and/ or symptoms of the treated teeth. purpose: the purpose of this study was to determine endodontic treatment failure in relation to various factors influencing it in teeth with periapical lesions (clinically and radiographically). materials and methods: teeth which had...
