BACKGROUND Endodontic treatment, involves removal of the dental pulp and its replacement by a root canal filling. Restoration of root filled teeth can be challenging due to structural differences between vital and non-vital root filled teeth. Direct restoration involves placement of a restorative material e.g. amalgam or composite directly into the tooth. Indirect restorations consist of cast m...
This article reports a case who was treated with immediate replacement of periodontally compromised mandibular incisors using the extracted incisors as a natural tooth pontic. Following extraction and root resection of the mandibular incisors, radicular pulp was cleaned and filled with composite resin and then bonded to adjacent teeth with fiber reinforced composite resin. This is a simple, eco...
abstract listening is a key and main tool in second language skill and its development is of prime concern to teachers and learners. furthermore, the application of technology in language classrooms has become more commonplace in the last fifty years. computer and the internet have made foreign language materials easy to access and use. so, the present study is an attempt to examine the effec...
the present study aimed at investigating the relationship between iranian efl teachers’ classroom management orientations and their teaching styles. additionally, the difference between male and female teachers’ teaching styles and classroom management orientations and their relationship with experience and age were explored. three hundred efl teachers filled in attitudes and beliefs on classro...
introduction : dentin removal during root canal instrumentation creates a weaker root structure and increases its potential to fracture. the aim of this in vitro experimental study was to compare fracture resistance of teeth filled with gutta-percha, and resilon using two different techniques. materials and methods: this study was performed on 105 single-canal extracted maxillary incisors. samp...
introduction: this study compared apical dye penetration using lateral condensation technique (lc) and lc technique with a reciprocal handpiece (mechanical lateral condensation or mlc) as a new method. materials and methods: forty-eight human extracted straight canine teeth were used. after crown amputation, the teeth were randomly divided into four experimental groups of 10 teeth each and two ...
INTRODUCTION The purpose of this study was to compare the ability of ProRoot mineral trioxide aggregate (PMTA) and Root mineral trioxide aggregate (RMTA) as root-end filling materials, and Portland cement (PC) to prevent bacterial leakage through filled root end cavities. MATERIALS AND METHODS Fifty-one extracted human single rooted teeth were cleaned and shaped using a step back technique. T...
introduction: the purpose of this study was to evaluate the sealing ability of gray-colored mineral trioxide aggregate (gmta), white-colored mta (wmta), and resilon as root filling materials. materials and methods: sixty-six human maxillary central incisors were used in the present study. in the group a, 20 teeth were filled with gmta. in the group b, 20 teeth were filled with wmta and in the g...
OBJECTIVE The aim was to evaluate the influence of multiple factors on the periapical status of endodontically treated (ET) teeth. METHODS The patients were clinically and radiographically reevaluated after root canal therapy. The quality of the root-filled canals, coronal restorations, intraradicular posts, dental caries, and periodontal parameters were associated with the teeth's periapical...
Introduction: Vertical root fractures (VRFs) in endodontic treatment teeth are most serious complication. VRFs have a poor prognosis and usually result in tooth extraction. The purpose of this study was to evaluate the clinical outcomes of mineral trioxide aggregate (MTA) filled teeth for VRFs using by dental operate microscope (DOM). Methods: Fifty-two endodontic treatment teeth with VRFs were...
