Wear Resistance of Bulk-fill Composite Resin Restorative Materials Polymerized under different Curing Intensities.
INTRODUCTION The aim of this study was to assess the wear resistance of four bulk-fill composite resin restorative materials cured using high- and low-intensity lights. MATERIALS AND METHODS Twenty-four samples were prepared from each composite resin material (Tetric N-Ceram, SonicFill, Smart Dentin Replacement, Filtek Bulk-Fill) resulting in a total of 96 samples; they were placed into a mol...
متن کاملEffect of resin thickness, and curing time on the micro-hardness of bulk-fill resin composites
BACKGROUND Bulk-fill resin composite has been introduced, their manufacturers claimed that they can be applied in bulks of 4mm, without necessitating a prolonged curing time, or a light curing unit with increased irradiance. Thus this study was conducted to evaluate the effect of resin thickness, and curing time on the micro-hardness of two bulk -fill resin composites; Tetric Evo-Ceram [TE], an...

Objectives: Microleakage is the main concern in composite restorations. This study aimed to compare the microleakage of two bulk-fill and one conventional composite at two different time points. Methods: Class II cavities were prepared in 60 premolar teeth and divided into six groups of 20. Groups 1 and 4 were incrementally filled with Grandio composite. Groups 2 and 5 were filled with X-tra...
متن کاملOptical hazard evaluation of dental curing lights.
The potential ocular hazards associated with the use of dental curing lights were evaluated. Recommendations are provided for precluding exposure of personnel to hazardous levels of optical radiation. Users should not stare directly into the dental curing lights at distances shorter than 25 cm (which would not be a likely event). Eye protectors which filter wavelengths below 500 nm may be desir...
