Hardening of a dual-cure resin cement using QTH and LED curing units
OBJECTIVE This study evaluated the surface hardness of a resin cement (RelyX ARC) photoactivated through indirect composite resin (Cristobal) disks of different thicknesses using either a light-emitting diode (LED) or quartz tungsten halogen (QTH) light source. MATERIAL AND METHODS Eighteen resin cement specimens were prepared and divided into 6 groups according to the type of curing unit and...
متن کاملHardening of dual-cure resin cements and a resin composite restorative cured with QTH and LED curing units.
OBJECTIVE The aim of this study was to determine the effects of light intensity and type of light unit (quartztungsten-halogen [QTH] or light-emitting diode [LED]) on the hardening of various resin cements and a resin composite restorative. METHODS Disk specimens were prepared from 4 dual-cured resin cements (Variolink II, Calibra, Nexus 2 and RelyX ARC). Two QTH light-curing units (Visilux 2...

متن کاملColor Stability of a Microhybrid Resin Composite Polymerized with LED and QTH Light Curing Units
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...
متن کاملCuring efficiency of dual-cure resin cement under zirconia with two different light curing units
PURPOSE Adequate polymerization is a crucial factor in obtaining optimal physical properties and a satisfying clinical performance from composite resin materials. The aim of this study was to evaluate the polymerization efficiency of dual-cure resin cement cured with two different light curing units under zirconia structures having differing thicknesses. MATERIALS AND METHODS 4 zirconia discs...
