Abstract:

The shear bond strength (SBS) of Th eraCal LC to resin composite was evaluated in comparison to mineral trioxide aggregate (ProRoot MTA) and conventional glass ionomer cement (GIC) using two adhesive systems. A hole was prepared in 90 acrylic blocks (6 mm diameter, 2 mm deep) then fi lled with Th eraCal LC, MTA or Fuji IX (n=30/group). Each group was bonded with either etch and rinse or 1-step self-etch adhesive. Filtek Z250 composite was bonded to each capping material. Bond strength was tested in a universal testing machine and data were analyzed using 2-way ANOVA and Duncan�??s multiple range test (p<0.05). Th eraCal LC displayed the highest SBS (p<0.001). MTA bonded with the 1 step self-etch adhesive showed the lowest SBS (p<0.001), while SBS of Th eraCal LC and Fuji IX did not diff er between either adhesive (p>0.05). Th eraCal LC is the preferred choice in pulp capping procedures when using resin composite restorations.
