Objective The purpose of this prospective randomized clinical study was to compare the performance thermo-viscous bulk-fill resin composite versus conventional in proximal compound posterior restorations. Materials and Methods: A total fifty-four Class II cavities were prepared forty-seven patients. patients divided into two groups according type used (n=27).Group 1 : bulk fill (Viscalor,Voco) ...

To determine the influence of light curing units (LCUs) and material viscosity on degree conversion (DC) bulk-fill (BF) resin-based composites (RBCs) placed in deep cavity preparations. Four LCUs were tested: Valo cordless, Bluephase-G2, Poly wireless Radii-cal. Light irradiance was determined at 0 mm 6 distance to reading sensor. The following RBCs considered: Filtek BF, BF Flow, Opus Tetric N...

OBJECTIVES To assess compressive strength and effect of duration after photoactivation on the compressive strength of different dual cure bulk fill composites. METHODS Seventy-two disc shaped (4x10mm) specimens were prepared from three dual cure bulk fill materials, ZirconCore (ZC) (n=24), MulticCore Flow (MC) (n=24) and Luxacore Dual (LC) (n=24). Half of the specimens in each material were t...

Abstract Machining of fiber-reinforced composites produces delamination in the workpiece. In bidirectional long fiber fabric reinforced composites, depends on different parameters. this work, two parameters are studied: orientation angle respect to machining direction and distance warp yarn from trimmed edge until next dip below crossing fill. This work defines angles relating with cutting feed...
