AIM The aim of this study was to evaluate the minimum bactericidal concentrations (MBC) of root-end filling materials ProRoot MTA, MTA Angelus and IRM. MATERIALS AND METHODS Macrodilution broth method was used. Microorganisms used were: Staphylococcus aureus (ATCC 29213), Enterococcus faecalis (ATCC 29212) and Streptococcus mutans. Serial two-fold dilutions of root-end filling samples were pr...

objective: one of the principle purposes of root canal obturation is to obtain hermetic sealing of the root canal system. according to the development of technology, many materials are now used in root canal filling. an in vitro dye leakage study was performed to evaluate the apical sealability of white-colored mineral trioxide aggregate (wmta) and gray-colored portland cement (gpc) when used a...

introduction: the aim of this in vitro study was to compare the efficacy of protaper retreatment (protaper r) and mtwo retreatment (mtwo r) files in removing gutta-percha and guttaflow from endodontically treated straight root canals. methods and materials: the root canals of 60 human mandibular single-rooted premolars were prepared and randomly divided into two groups ( n =30). in groups a and...

PURPOSE To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material. METHODS Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated with MTA as the root-end filling materia...

the aim of this study was to evaluate the marginal adaptation of biodentine in comparison with mineral trioxide aggregate (mta) and intermediate restorative material (irm), as a root end filling material, using scanning electron microscopy (sem).thirty permanent maxillary central incisors were chemo-mechanically prepared and obturated. three millimetres of the root end were resected and 3mm ret...

Nowadays, in endodontic field mineral trioxide aggregate (MTA; Dentsply, Tulsa Dental, Tulsa, OK, USA) has been introduced and widely used in many indications such as root-end filling, perforation repair, apexification, and pulp capping. Traditionally, various materials, such as amalgam, zinc oxide eugenol (ZOE), Intermediate Restorative Material (IRM; Dentsply Caulk, Milford, DE, USA), and sup...

AIM To compare the technical quality and long-term outcomes of root canal treatment by general practitioners of a Swedish Public Dental Service, before and after an endodontic education including Ni-Ti rotary technique (NiTiR). METHODOLOGY A random sample was compiled, comprising one root filled tooth from each of 830 patients, treated by 69 general practitioners participating in the educatio...

1. The infected root canal space cannot be cleaned and disinfected with the standard root canal protocol using an aggressive procedure with endodontic files. 2. After the disinfecting phase of treatment has been completed, filling the root canal is difficult because the open apex provides no barrier for containing the root filling material without impinging on periodontal tissues. 3. Even after...

INTRODUCTION The aim of this study was to obtain a three-dimensional analysis of the isthmus area of the mesiobuccal root canal system in mandibular molars using high-resolution micro-computed tomography (μ-CT) scanning and to measure the amount of debris and root filling material in the isthmus after instrumentation/irrigation and root filling. METHODS Mandibular molars with two separated me...

INTRODUCTION The outcome predictors identified with data from periapical radiographs (PA) and cone-beam computed tomography (CBCT) scans might not be the same. This retrospective study evaluated various factors that might affect the outcome of root canal therapy. METHODS In total, 115 teeth (143 roots) with vital pulps were endodontically treated and followed up 2 years after treatment. Multi...
