INTRODUCTION Root canal obturation seals the root canal system to prevent re-entry and/or growth of microorganisms. The provision of an appropriate restoration to coronally seal the access cavity affects the success of endodontic treatment. The purpose of this study was to evaluate the coronal microbial leakage in root canals that were either filled by(More)
INTRODUCTION The aim of this in vitro study was to compare the effectiveness of three intracanal medicaments in disinfecting the root canal and dentin of experimentally infected human teeth with Enterococcus faecalis (EF). MATERIALS AND METHODS One hundred extracted human single-rooted teeth were used. After root canal preparation, teeth were mounted in(More)
INTRODUCTION The aim of this study was to compare the cytotoxicity of ProRoot MTA (PMTA), Root MTA (RMTA) and Portland cement (PC) on human gingival fibroblasts (HGFs). MATERIALS AND METHODS The extracts of the test materials were placed close to human gingival fibroblasts (HGFs) within 96-well plates. Cellular viability was assessed using MTT assay in(More)
Familiarity with the intricacies and variations of root canal morphology is essential for successful endodontic treatment. Maxillary central and lateral incisors are known to be single-rooted with one canal, however, this case report describes endodontic treatment of maxillary central and lateral incisors with two buccopalatal root canals.
BACKGROUND The aim of this study was to compare push-out bond strength of a new bioceramic endodontic sealer, EndoSequence BC sealer (Brasseler USA, Savannah, GA), used with gutta-percha in the presence or absence of phosphate-buffered saline solution (PBS) within the root canals. MATERIALS AND METHODS Forty single-rooted human teeth were prepared and(More)
OBJECTIVE Use of rotary Nickel-Titanium (NiTi) instruments for endodontic preparation has introduced a new era in endodontic practice, but this issue has undergone dramatic modifications in order to achieve improved shaping abilities. Cone-beam computed tomography (CBCT) has made it possible to accurately evaluate geometrical changes following canal(More)
OBJECTIVE A detailed knowledge of root canal anatomy is a prerequisite for successful endodontic treatment. Such information is highly dependent upon the ethnicity of the population of interest. Lack of sufficient national information concerning internal anatomy can lead clinicians to increase their rate of treatment success. The aim of this study was to(More)
INTRODUCTION The aim of this study was to compare the accuracy of cone-beam computed tomography (CBCT), digital radiography and tooth sectioning in evaluating root canal morphology of mandibular incisors in an in vitro setting. METHODS AND MATERIALS A total of 76 samples were imaged using CBCT, and digital radiography in straight and angled views. The(More)
OBJECTIVES Cytotoxic effects of obturation materials were tested in presence and absence of endotoxin on human monocytes in vitro. MATERIALS AND METHODS Human monocytes from THP-1 cell line were cultured. Three millimeters from the tip of each Resilon and gutta percha points were cut and directly placed at the bottom of the culture wells. Cultured cells(More)
A case with two simultaneous dens invaginations (DIs) and one dens evagination (DE) in a permanent maxillary lateral incisor is reported for the first time in a 21-year-old girl. DE known as talon cusp of the anterior teeth is a rare entity and its co-existence with DI has been reported scarcely in the literature. Simultaneous occurrence of two DIs with one(More)
