Effect of Universal Adhesive on Shear Bond Strength of Resin Composite to Feldspathic Ceramic
Objective: To investigate the shear bond strength between resin composite and feldspathic ceramic using a new adhesive system (Single Bond Universal Adhesive) compared with conventional technique for ceramic repair.
Materials and Methods: Twenty one cylindrical specimens were fabricated with feldspathic ceramic; each specimen has two bond area tests (42 bond areas). All specimens were etched with 5% hydrofluoric acid for 60 seconds, rinsed and air dried. Specimens were randomly divided into three groups, seven specimens and fourteen bond areas each. Group 1 treated with silane coupling agent and applied Scotchbond™ Multi-Purpose adhesive. Group 2 treated with silane coupling agent and applied Single Bond Universal Adhesive. Group 3 applied Single Bond Universal Adhesive. Adhesive layer of all specimens were light cured for 20 seconds. Each bond area on feldspathic ceramic specimen was bond with resin composite in diameter of 3 mm and 2 mm thick and light cure for 40 seconds. All specimens were then stored in 37°C distilled water for 24 hours. Universal Testing Machine was used for shear bond strength testing at a cross-head speed of 0.5 mm/ min. Mean shear bond strength was analyzed by One-way ANOVA and Tukey multiple comparison test (p<0.05). The failure surfaces were examined by light stereomicroscope.
Results: The highest mean shear bond strength was Group 2 (26.93±5.53 MPa) followed by Group 1 (26.74±4.58 MPa) and Group 3 (18.51±4.24 MPa). Control group and the group used silane with Single Bond Universal Adhesive showed significant higher shear bond strength compared to non-silane group. Most of the failure were cohesive in feldspathic ceramics.
Conclusions: Using silane coupling agent with Single Bond Universal Adhesive could improve shear bond strength of resin composite and feldspathic ceramic.
