This study was conducted to observe the healing process of intentional lateral root perforation repaired with mineral trioxide aggregate (MTA). Forty-eight root canals of dogs' teeth were instrumented and filled. After partial removal of the filling, an intentional perforation was made with a bur in the lateral area of the root. The perforations were repaired with MTA or Sealapex (control group...
This experiment investigated the ability of tooth-colored mineral trioxide aggregate (MTA) to maintain an apical seal in the presence of bacteria when contaminated with blood, saline or saliva. Ninety extracted human teeth with single canals were randomly placed into six groups of 15. Canals were prepared to size 50. The apical 3 mm of each root was removed and 3 mm root-end preparations were m...
AIM The aim of this study was to evaluate the fracture resistance of simulated immature teeth, when the root canals were completely filled either with mineral trioxide aggregate (MTA) or Biodentine, comparing with that of roots filled with apexification procedure. MATERIALS AND METHODS Sixty mandibular premolar teeth with single, straight canals decoronated at cementoenamel junction were divi...
AIM Mineral trioxide aggregate (MTA) is the material of choice for apical barrier techniques during root canal treatment of teeth with open apices. However, the precise control of MTA during the placement of an apical plug is challenging. This article describes the outcomes of unintentional extrusion of MTA into the periradicular tissue during apical barrier treatment in three cases. SUMMARY ...
Introduction: Mineral trioxide aggregate (MTA) has a variety of possible uses, including root-end filling material due to its excellent sealing ability in the presence of moisture and a high degree of biocompatibility. Aim: This case report demonstrates the use of MTA as an obturating material to promote periapical healing of root canals with large apical rarefactions. Materials and Methods: An...
The purpose of this study was to evaluate whether intracoronal delivery of an apical barrier of mineral trioxide aggregate (MTA) placed ultrasonically, non-ultrasonically, or ultrasonically with the addition of an intracanal composite resin provided a better seal against bacterial leakage. A second purpose was to determine whether intracanal composite resin or gutta-percha and sealer placed aga...
INTRODUCTION Broken instruments in root canals complicate routine endodontic treatment. This study aimed to compare apical microleakage in root canals containing broken rotary instruments filled with mineral trioxide aggregate (MTA), calcium-enriched mixture (CEM) cement, laterally compacted gutta-percha and injected gutta-percha. METHODS AND MATERIALS In this in vitro, experimental study, 80...
OBJECTIVE This study compared the push-out bond strength of EndoSequence Root Repair Material (ERRM) and Bioaggregate (BA), new bioceramic materials, to that of mineral trioxide aggregate (MTA) after incubation in phosphate-buffered saline (PBS), a synthetic tissue fluid, for either 1 week or 2 months. MATERIALS AND METHODS One-hundred and twenty root sections were filled with ProRoot MTA, BA...
Materials and Methods: 15 single rooted premolars were selected and middle portion of each root was sectioned perpendicular to the long axis to produce two discs of 2.00 ± 0.05 mm thickness using a diamond disk. 30 root slices were produced and canal lumen was widened using Gates Glidden drills to produce standardized internal diameter of 1.3mm and root sections were filled with ERRM, MTA and B...
