BACKGROUND The common recovery of Candida albicans and Enterococcus faecalis from failed root canals of teeth in which previous treatment has failed is notable. These organisms have been shown to be resistant to antimicrobial action of calcium hydroxide but are sensitive to chlorhexidine gluconate. The aim of the present in vitro study was to investigate(More)
AIM The objective of the present study was to evaluate and compare the wetting behavior of three different root canal sealers on the root canal dentin surface treated with irrigants and their combination. MATERIALS AND METHODS Decoronation and apical third resections of 27 extracted single-rooted human mandibular premolars were done. The roots were then(More)
The purpose of this article is to report a rare case of orthodontically induced external root resorption of a maxillary left central incisor with a large periapical radiolucency; it was treated successfully with a conservative approach that included the use of calcium hydroxide. The tooth was nonvital and had grade III mobility. It was treated(More)
INTRODUCTION Accurate determination of working length (WL) is a critical factor for endodontic success. This is commonly achieved using an apex locator which is influenced by the presence or absence of the apical constriction. Hence, this study was done to compare the accuracy of two generations of apex locators in teeth with simulated apical root(More)
