INRODUCTION High-quality filling of root canals is one of indicators of successful endodontic treatment. However, poor-quality of the filling is still a common phenomenon in the work of general practitioners. Better training of dental students of modern odontology is possible solution of the problem. The aim of this study was to evaluate the quality of root canal filling performed by undergradu...

OBJECTIVE The aim of this study was to evaluate whether the gap between the post restoration and the remaining root canal filling had an impact on the periapical health of endodontically treated teeth in a Turkish subpopulation. STUDY DESIGN Digital panoramic radiographs, evaluated for this cross-sectional study, were randomly selected from files of patients who attended to Yeditepe Universit...

Objectives This study evaluated the amount of remaining root canal filling materials after retreatment procedures performed by undergraduate students using manual, rotary, and reciprocating techniques through micro-computed tomographic analysis. The incidence of instrument fracture and the instrumentation time were also evaluated. Materials and Methods Thirty maxillary single rooted teeth wer...

Background: The education of undergraduate dental students in endodontics should be of high standards to enable newly graduate dentists to deal with the most commonly encountered endodontic clinical problems. Hence, the objective of this study is to evaluate radiographically the quality of root canal fillings done by undergraduate students in the College of Dentistry, King Khalid University, Sa...

BACKGROUND Various materials have been added to mineral trioxide aggregate to enhance its properties. This study was aimed to compare the sealing efficacy of MTA with and without nanosilver using bacterial leakage approach. MATERIAL AND METHODS Seventy canine teeth were prepared and obturated. Then, after apical resection, the root-end cavities were prepared by ultrasonic retrotips. Teeth wer...

AIM The aim of this in vitro study was to assess the microleakage of composite restorations following contamination of access cavity with root canal filling materials of primary teeth. MATERIALS AND METHODS Forty primary canines were selected for this study. Standardized access cavity on the lingual surface of the canine was prepared. The margins of preparation were ended on enamel. The teeth...

Objective: To investigate the effect of warm gutta-percha filling with microscopic root canal technique. Methods: 120 patients with pulposis treated in our hospital from February, 2014 to December, 2015 were enrolled and randomized equally into observation and control group. The patients in the control group were treated with traditional root canal therapy, but those in the observation group we...
