AIM To evaluate the radiographic technical quality of root fillings performed by undergraduate students at a dentistry faculty in Turkey. METHODOLOGY A random sample of 2000 records of patients who received dental treatment at the Faculty of Dentistry, University of Gazi between 2000 and 2003 was investigated. The final sample consisted of 1,893(More)
AIM The aim of this study was to evaluate by means of radiographs the technical quality of root fillings performed by dental practitioners. METHODS AND MATERIAL Standardized periapical radiographs were made on 484 patients who received endodontic treatment in private practice. A total of 831 endodontically treated teeth with 1448 roots were evaluated for(More)
AIM To compare the fracture resistance of roots filled with different materials. METHODOLOGY Thirty-four freshly extracted human maxillary central incisor teeth with similar dimension were selected. Crowns were sectioned at the cemento-enamel junction, and the length of the roots were adjusted to 13 mm. Following the preparation of the root canals and(More)
INTRODUCTION Our objective was to determine the effects of intracoronal bleaching on the shear bond strength and failure side location of metallic brackets at 2 times (bleaching immediately before bonding and 30 days before bonding). METHODS Sixty freshly extracted mandibular incisors were randomly divided into 3 groups; each group contained 20 teeth.(More)
AIM To evaluate the apical extrusion of debris associated with several root canal preparation systems in vitro. METHODOLOGY Forty-five extracted human mandibular premolars with single canals and similar lengths were used. The root canals were instrumented using ProTaper Next (Dentsply Maillefer, Ballaigues, Switzerland), Twisted File (SybronEndo, Orange,(More)
OBJECTIVE To evaluate the antimicrobial effect by measuring the minimum inhibitory concentration MIC and minimum bactericidal concentration MBC of propolis, BioPure MTAD, 5% sodium hypochlorite (NaOCl), and 2% chlorhexidine CHX on Enterococcus faecalis (E. faecalis) and Candida albicans (C. albicans) in vitro. METHODS This study was performed in the(More)
OBJECTIVE The aim of this study was to assess the solubility of the new root canal sealer Epiphany and to compare it with 2 conventional sealers against 2 organic solvents commonly used in retreatment. STUDY DESIGN Standardized cylindric glass molds 5 mm wide and 2 mm high were filled with freshly mixed root canal sealers AH Plus, Ketac-Endo, and(More)
OBJECTIVE The aim of this study was to determine how physical and morphological properties affect the fracture resistance of roots, and which criteria are important for root specimen standardization in fracture resistance studies. MATERIALS AND METHODS Seventy-five freshly extracted human canine teeth were selected. Crowns were sectioned from the(More)
OBJECTIVES The aim of this study was to assess the apical sealing ability of different core materials used with Epiphany(TM) sealer and to evaluate the effect of Resilon/Epiphany(TM) system on creating an apical mono-block seal. METHODS Fifty-five extracted human teeth were used. Forty-five were selected and randomly divided into three groups and ten(More)
PURPOSE The purpose was to evaluate temperature increases during dowel space preparations with oval and circular fiber dowel systems. MATERIALS AND METHODS This study included 42 single-rooted human mandibular premolars. Roots were scanned with cone-beam computerized tomography (CBCT) to determine the ovoid root canal morphology. Root canals were treated(More)
