title: Bonding performance of two newly developed self-adhering materials between zirconium and dentin.
abstract: OBJECTIVE
  This study evaluated the effect of four resin materials on the shear bond strength (SBS) of a ceramic core material to dentin.
  
  
  METHODS
  Sixty molar teeth were embedded in a self-curing acrylic resin. All specimens were randomly divided into four groups of teeth, each according to the resin cement used. Sixty cylinders were then luted with one of the four resin materials to dentin (GC EQUIA, Panavia F, Variolink II and Vertise). Then, specimens were stored in distilled water at 37 o C for one day. Shear bond strength of each specimen was measured using a universal testing machine at a crosshead speed of 0.5 mm/minute. The bond strength values were calculated in N, and the results were statistically analyzed using a Kruskal-Wallis and Bonferroni corrected Mann-Whitney U tests.
  
  
  RESULTS
  The shear bond strength varied significantly depending on the resin materials used ( P < 0.05). The specimens luted with GC EQUIA showed the highest shear bond strength (25.19 ± 6.12), whereas, the specimens luted with Vertise flow (8.1 ± 2.75) and Panavia F (11.17 ± 3.89) showed the lowest.
  
  
  CONCLUSIONS
  GC EQUIA material showed a higher shear bond strength value than other resin materials.
