INTRODUCTION The present study was designed to investigate the bond strength produced by Epiphany and Epiphany SE to root canal dentin. METHODS A sample of 36 human upper canines was prepared and assigned to experimental groups (n = 12), designated as group 1, Resilon/Epiphany; group 2, Resilon/Epiphany SE; and group 3, AH Plus/gutta-percha. After the filling procedures, each tooth was prepar...

background: reinforcement of root canals obturated with resilon was reported by several investigators, but no studies reported the reinforcement of overtly fl ared root canals obturated with resilon material. the aim of this study was to investigate the fracture resistance of overtly fl ared root canals fi lled with resilon as compared to similar root canals fi lled with gutta-percha (gp). mate...

The appearance of Linked Open Data (LOD) was an important milestone for reaching a Web of Data. More and more RDF data sets get published to be consumed and integrated into a variety of applications. Pointing out one application, Linked Data can be used to enrich web pages with semantic annotations. This gives readers the chance to recall Semantic Web’s knowledge about text passages. RDFa provi...

OBJECTIVE To assess the effects of different final irrigants on the bond strength of bonded root filling materials, Epiphany/Resilon and Epiphany self-etch (SE)/Resilon. MATERIALS AND METHODS The root canals of eighty single-rooted extracted human teeth were prepared. After the smear layer was removed using 17% EDTA, the samples were randomly divided into eight groups. In groups 1 and 2, no a...

Introduction: After endodontic procedures, root canal reinfection is a main concern for dentists. However, application of a proper apical seal can prevent such contamination. Therefore, it seems necessary to study the factors affecting the development of a suitable apical seal. Materials and Methods: In this study, 64 extracted human single-canal premolars were used. An equal length of roots wa...

introduction: the aim of this study was to evaluate the apical and coronal sealing of endodontic fillings promoted by the associations of sealer 26/gutta-percha, endofill/gutta-percha and resilon/ epiphany. materials and methods: it was used 38 human canines, 10 teeth for each test group and 4 teeth for each control group. after teeth conventional endodontic treatment, they were immersed in sal...
