The purpose of this study was to compare the shear bond strength (SBS) four resin-based composite materials a silicate-based cement using “no-wait” universal with self-etch (SE) and etch-and-rinse (ER) modes. Acrylic blocks (n=80, 2mm depth, 5mm diameter central hole) were prepared. holes filled BiodentineTM (BD) divided into 4 main groups (n=20) according resin type used: Group FZ250: FiltekTM...

AIM The purpose of this study was to investigate the effect of light-emitting diode (LED) light curing units (LCUs) compared with halogen LCUs on the shear bond strength (SBS) of one nanofill composite (Filtek Supreme) and one microhibrid composite (Artemis) with self-etch adhesives. METHODS AND MATERIALS The buccal surfaces of 60 non-carious extracted human molars were flattened to expose de...

Introduction: Discoloration of resin composites is a common reason for replacement of these restorations. The aim of this study was to eva-luate the influence of different light curing de-vices on color stability of a microhybrid resin composite.  Materials and Methods: 80 disc-shaped speci-mens (8 mm in diameter, 2-mm height) were fabricated from filtek Z250 resin composite. Specimens wer...

The purpose of this in vitro study was to compare the effect staining, glazing, and polishing on wear behavior stabilized zirconia with 5 mol% yttrium oxide (5Y-TZP) opposing 5Y-TZP, leucite-reinforced ceramic (LC), lithium disilicate (LD), microhybrid composite resin (MCR). Hemispheres 5Y-TZP were divided into six groups (n = 10) according finishing procedure: C (control), S (staining), G (gla...
