title: Shear bond strength of a self-etched resin cement to an indirect composite: effect of different surface treatments.
abstract: OBJECTIVE
  The aim of this study was to compare the shear bond strength of resin cement (Rely X-U200) bonded to differently conditioned indirect composite samples.
  
  
  METHODS
  Sixty-six composite resin specimens (5 mm in diameter and 3 mm in thickness) were prepared with an indirect composite resin (Grandia) and randomly divided into six groups. Surfaces of the samples were treated with one of the following treatments; %37 phosphoric acid etching, sandblasting, 1,5 W, 2 W and 3 W erbium, chromium: Yttrium-scandium-gallium-garnet laser application. An untreated group was used as a control. In each group surface of the sample was analyzed with scanning electron microscopy. The remaining samples (n = 60) were built up with a self-adhesive resin cement (Rely X-U200) 3 mm in diameter and 2 mm height. After 24 h water storage at 37°C, the prepared specimens were submitted to shear bond strength test. One-way analysis of variance was used to analyze the bond strength values of different groups.
  
  
  RESULTS
  Highest shear bond strength values were observed in sandblasting group however there were not statistical difference among the tested surface treatment methods.
  
  
  CONCLUSIONS
  In Shear bond strength of resin, cement was independent of the surface conditioning methods applied on tested indirect resin composite.
