TI  - Shear bond strength of several new core materials.
PG  - 154-8
AB  - This study compared the shear bond strengths of three core materials: a light 
      activated glass-ionomer cement (VariGlass VLC), a fluoride-release dual cure 
      composite resin (Fluoro Core), and a conventional silver-reinforced glass-ionomer 
      cement (Miracle Mix) when cured to dentin. Fifty-four noncarious molar teeth were 
      extracted, cleaned, mounted in acrylic resin, and sectioned horizontally to 
      expose the dentin surface. Each material was mixed according to manufacturer's 
      instructions, applied in a premade mold to the exposed dentin, and then cured. 
      The specimens were randomized into three group (six teeth from each material) and 
      stored (37 degrees C, 100% humidity) for 15 minutes, 24 hours, and 24 hours and 
      were then thermocycled (5 degrees to 55 degrees C) for 125 cycles. The specimens 
      were tested for shear bond strength with the Instron universal testing machine. 
      The differences among time groups were not statistically significant except for 
      Miracle Mix and VariGlass VLC cements, which showed a greater improvement with 
      thermocycling. This study indicated that the FluoroCore resin exhibited the 
      greatest shear bond strength of the core materials and that VariGlass VLC cement 
      had greater bond strength than Miracle Mix cement except after thermocycling, 
      when VariGlass VLC cement and FluoroCore resin were not significantly different.
