title: Shear bond strength of one-step self-etch adhesives with different co-solvent ingredients to dry or moist dentin.
abstract: OBJECTIVE
  To evaluate the shear bond strength of one-step self-etch adhesives with different co-solvent ingredients to dry or moist dentin.
  
  
  METHODS
  A total of 60 extracted teeth were used in this study, and were divided according to the adhesive systems and dentin conditions into 6 groups of 10 teeth each [Xeno III - dry dentin, Xeno III - moist dentin, Adper Prompot L-Pop - dry dentin, Adper Prompot L-Pop - moist dentin, iBond - dry dentin, and iBond - moist dentin]. Resin composite cylinder was built up on each specimen, and then thermocycled. A shear load was applied to the specimens using universal testing (Instron machine) at a cross-head speed of 0.5 mm/min until failure occurred. Data were statistically analyzed by one-way ANOVA and Bonferroni multiple comparison test at 95% confidence level.
  
  
  CONCLUSIONS
  BASED ON THE FINDINGS OF THIS STUDY: The highest mean shear bond strength to dry dentin was seen when Xeno III containing ethanol co-solvent ingredient was used. The highest mean shear bond strength to moist dentin was seen when iBond which contains acetone co-solvent ingredient was used. In the absence of a co-solvent ingredient in self-etch adhesive (Adper Prompot L-Pop), the mean shear bond strengths to dry and moist dentin were low with no significant difference between them.
