The objective of this study was to evaluate the sealing ability and antibacterial activity of Ca3SiO5/CaCl2 composite cement. Fifty maxillary anterior teeth were instrumented according to step-back technique and filled with experimental and control materials. To evaluate the sealing ability, a fluid transport model using glucose was employed for quantitative analysis of endodontic microleakage....

the main objective of endodontic therapy is the thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material. failure to find and fill a canal contributes toward the failure of endodontic therapy .the root canal anatomy of mandibular first molars is complex. studies of the morphologic structure of root canal systems have d...

Aim: The aim of this study was to investigate the variations in root canal morphology of the Mandibular premolars in the population of Uttarakhand using periapical radiographs. Objective: For the success of the endodontic treatment, shaping and sealing of the root canals in the three dimension is mandatory, for which the thorough understanding of the root canal system and its variation is impor...

an important goal in endodontic treatment. To achieve this goal, the root canal filling must seal the pulp space both apically and laterally to prevent further apical irritation from incomplete elimination of bacterial products.1 In the past, the adequacy of root canal filling procedure was primarily based on its vertical appearance on the dental radiograph and whether the material had reached ...

Background: Aim of the study was to evaluate sealing ability of five different root end filling materials by dye penetration method. Materials and Methods: About 100 extracted maxillary central incisors were sectioned at Cementoenamel junction. Access cavities were prepared, instrumented chemo-mechanically, and obturated with laterally condensed gutta-percha and AH Plus sealer. Access cavities ...

background: sealing ability is one of the most important features of endodontic sealers. the purpose of this in vitro study was to compare the sealing ability of a resin-based sealer with a mineral trioxide aggregate-based sealer. materials and methods: a total of 60 single-rooted extracted human teeth were randomly divided into two experimental groups (n = 25) and two control groups (n = 5). a...

OBJECTIVE The aim of this study was to make a quantitative assessment of the sealing ability of Super-EBA, IRM, and Pro Root MTA root-end fillings subjected to 3 different finishing techniques. STUDY DESIGN Eighty-one ultrasonically prepared root-end cavities in human canines were separated randomly into 3 test groups of 27 roots each. The cavities were filled with Super-EBA, IRM, or Pro Root...

Context Endodontic retreatment is performed in teeth with endodontic failures. The main goal of retreatment is cleaning and shaping of the root canal with removal of old root filling material. Hand instruments and rotary instruments are mainly used for removing this filling material. Aim of Study To compare the relative efficacy of three rotary instrumentation systems for removal of gutta-per...
