Sealer placement techniques have not been examined in teeth with curved canals prepared with Lightspeed instruments. Three traditional methods of placing sealer were studied, using 45 extracted human single-rooted teeth, divided into 3 groups of 15. Root canal preparations were made with Light-speed nickel-titanium, engine-driven instruments. AH26 sealer was applied with either K-file, lentulo ...

Cone beam computed tomography (CBCT) is a recent three-dimensional (3D) radiographic imaging modality used for the accurate diagnosis, management and follow-up of endodontic problems. In tooth with open apex and periapical lesion, the use of new obturation material such as white mineral trioxide aggregate (wMTA) facilitates faster and more predictable closure of root apex and periapical healing...

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 To evaluate the fracture resistance of simulated immature teeth with an apical plug of biodentine followed by composite resin vs total obturation with biodentine tested immediately and after 3 months of aging and also to find out the chemical composition of dentin in contact with these materials. Materials and methods Extracted human maxillary central incisors with simulated immature apex...

Relevance . Under study is based on the fact that every year number of patients with complicated forms caries increases, in addition, complexity a treatment manipulations, often leads to various errors and complications at all stages endodontic treatment. Aim To evaluate tightness root canal obturation depending selected technique antiseptic canals. Materials methods 40 teeth extracted due chro...

The American Association of Endodontists defines root canal obturation as the complete, three-dimensional obturation of the root of canal system, as close as possible to the cemento-dentinal junction without overor underfilling. Moreover, obturation should be carried out using a minimal amount of biocompatible sealer and the obturated canal should demonstrate a radiographically dense filling ex...

A split-tooth model with artificially created intracanal wall defects was used to compare three gutta-percha (GP) obturation techniques, cold lateral, warm lateral, and warm vertical. The techniques were evaluated and compared based on defect replication quality as a function of defect location and size. The obturations were evaluated on an ordinal scale, 0 to 4, based on how much each defect w...

Polyurethane-based micro- and nano-hybrid composites were produced with controlled porosity to be used as obturation materials. In addition to hydroxyapatite (HAp) micro-particles in the composites, two different ceramics particle types were also added: alumina micro-particles and silica nano-particles. Particles of different sizes provide the materials with improved mechanical properties: the ...

introduction: the aim of this study was to evaluate the effects of training duration and case difficulty on the radiographic quality of root canal fillings performed by dental students in saudi arabia. methods and materials: a longitudinal cohort study was conducted at king saud university. root canal treatments performed by 55 dental students from 2012-2014 were included in the study. each stu...
