Achieving adequate disinfection and preventing reinfection is the major goal in endodontic treatment. Variation canal morphology open porosity of dentine prevents achieving complete disinfection. Questionable biocompatibility materials as well a lack sealing ability questions usefulness current obturation methods. With novel approach based on use boron-doped diamond (BDD) electrodes having show...

The amounts of apical enlargement have been a controversial issue for a long time. The enlargement of the apical part of the canal may severely impact the endodontic prognosis. Enlargement of the apical portion to a larger size may negatively affect the ability to control the filling material during root canal obturation. In addition, an open-apex increases the risk for overfilling which has be...

background and aims. various materials and methods have been introduced for obturating cleaned and shaped root canal systems. this in vitro study aimed to evaluate the sealing ability of single-cone obturation technique with mineral tri-oxide aggregate and calcium-enriched mixture based on bacterial leakage approach. materials and methods. sixty-four single-canal teeth were prepared and randoml...

Root canal retreatment is often the preferred method of treating a tooth in which root canal treatment has failed. Part one of this two-part article discusses reasons for failure of root canal treatment, case assessment and treatment planning. Part two describes some of the practical techniques that are available to the practitioner and the rationale for root canal retreatment. Dent Update 2004...

Non surgical root canal treatment is carried out to salvage the teeth in oral cavity. Although the success rate is found to be ranging from 81-95%, for variety of reasons failure of root canal is still seen in day to day practice. This is a cross sectional study done in Nepali population to evaluate the causes for such failures. It was found that inadequate obturation (45%) was the major cause ...

The meticulous knowledge of anatomic characteristics and their variations is essential for the clinician. Radix entomolaris (RE) is one such anomaly where an extra root is present on the distolingual aspect of the mandibular first molar. 18-year-old patient was referred for the root canal treatment of mandibular right and left first molars. Intraoral periapical radiograph revealed additional pe...

The aim of this study was to compare the apical sealing ability of three different obturation techniques using an electrochemical evaluation and evaluating dye penetration. One hundred and thirty-two maxillary anterior teeth were randomly divided into six groups. There were 20 teeth in each group. The teeth were obturated as follows: Groups 1 and 4 with Thermafil, Groups 2 and 5 with System B, ...

Recognition of aberrant root canal configurations is critical to successfully negotiate and treat a one such aberrancies C shape system. The fins webs present in system presents challenge debridement obturation. Knowledge variations through advanced imaging modalities like CBCT, rotary hand instruments assisted with ultrasonics modified obturation techniques aid effective management shaped cana...
