title: Bond strengths of a silorane composite to various substrates.
abstract: OBJECTIVE
  To evaluate the shear bond strength (SBS) of a novel low-shrink posterior resin composite (Filtek LS) to various substrates.
  
  
  METHODS
  The dedicated LS System Adhesive was used to bond Filtek LS to bovine dentin, ground bovine enamel, resin-modified glass-ionomer liner (Vitrebond Plus), conventional glass-ionomer restorative material (Fuji IX GP Extra), and bovine dentin previously exposed to zinc oxide-eugenol (IRM) (n=10 for each group). Vitrebond Plus and Fuji IX GP Extra substrates were fabricated by filling standardized preparations that had been made in epoxy resin. Adper Scotchbond SE/Filtek Z250 was used as a control. Composites were applied using the Ultradent specimen former. The bonded specimens were stored in water at 37 degrees C for 24 hours, and SBS testing was done using an Instron universal testing machine. The data were analyzed using ANOVA and Tukey-Kramer HSD test at a significance level of 0.05.
  
  
  RESULTS
  The mean SBS values of the Filtek LS system were generally somewhat lower than the values of Adper Scotchbond SE/Filtek Z250 to the various substrates, but the differences were not statistically significant. Exposure of dentin to IRM resulted in a statistically significant reduction in the mean SBS values of Adper Scotchbond SE/Z250 and a slight but statistically insignificant reduction for the Filtek LS system.
