introduction: vertical root fracture (vrf) is common in endodontically treated teeth. conventional and digital radiographies have limitations for detection of vrfs. cone-beam computed tomography (cbct) offers greater detection accuracy of vrfs in comparison with conventional radiography. this study compared the effects of metal artifacts on detection of vrfs by using two cbct systems. methods a...

Aim. To determine the root and canal morphology of permanent maxillary first molars in a Sri Lankan population with special emphasis on the presence of a second canal in the mesiobuccal root. Materials and Methods. One hundred and fourteen permanent maxillary first molars were examined. The root numbers of the molars were recorded. Root canal morphology was studied using a clearing technique. T...

UNLABELLED The aim of this study was to evaluate the incidence of intraradicular retention and the prevalence of different types of posts used for the restoration of endodontically treated teeth, in clinical practice. MATERIALS AND METHODS The study was performed on 94 digital panoramic radiographies that allowed a comprehensive appreciation. Root canal fillings and the posts were identified ...

AIM To compare histological responses to zinc oxide-eugenol (ZOE) and calcium hydroxide (CH) pulpectomies in primary molar teeth with inflamed pulps. STUDY DESIGN This was an experimental study in 17 juvenile baboons (Papio ursinus). METHODS Pulpitis was induced with fresh human carious dentine or Streptococcus mutans placed into occlusal cavities in 78 primary molars; after 14 days a pulpe...

INTRODUCTION Vertical root fracture (VRF) is common in endodontically treated teeth. Conventional and digital radiographies have limitations for detection of VRFs. Cone-beam computed tomography (CBCT) offers greater detection accuracy of VRFs in comparison with conventional radiography. This study compared the effects of metal artifacts on detection of VRFs by using two CBCT systems. METHODS ...

INTRODUCTION Mineral trioxide aggregate (MTA) was developed because existing materials did not have the ideal characteristics for orthograde or retrograde root-end fillings. MTA has been recommended primarily as a root-end filling material, but it has also been used in pulp capping, pulpotomy, apical barrier formation in teeth with open apexes, repair of root perforations, and root canal fillin...

The aim of this review was to identify and analyse all studies related to the effects of alkaline materials used in dentistry on roots of teeth. The first part of the review focused on mechanical property alterations of root dentine due to sodium hypochlorite (SH) used as an irrigant solution based on MeSH (Medical Subject Heading) terms from a previous study by Pascon et al in 2009. The second...

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...
