| Summary: | Background: All ceramics are the material of choice for
aesthetic tooth replacements. The success of all ceramic
restoration depends on the bond between the ceramic and the
tooth surface hence this study was done to evaluate the shear
bond strength of Feldspathic CAD/CAM ceramic with <5%
hydrofluoric acid and hydrofluoric acid combined with silane
coupling agent.
Aim: To evaluate the shear bond strength of Feldspathic CAD/
CAM ceramic with Dentin using bonding agents Prime & Bond
NT, XenoIII and surface treatments <5% hydrofluric acid,
hydrofluric acid combined with silane coupling agent.
Materials and Methods: Forty cylinders with 6mm diameter
and 5mm height were milled from CEREC Blocs through CAD/
CAM technology. Cerec blocks were bonded to etch freshly
extracted tooth surface using a self etch and total etch bonding
agent. The samples were divided into 4 groups. Group A1-
Ceramic cylinders were treated with < 5% HF and bonded using
Prime & Bond NT and Variolink II. Group A2- treated with < 5%
HF and silane coupling agent and bonded same as group A1.
Group B1- treated with < 5% HF and bonded using Xeno III and
Variolink II. Group B2- treated with < 5% HF and silane coupling
agent, and bonded same as Group A3. The shear bond strength
was evaluated after 24 hours by Storing in distilled water in
Instron 3385 universal testing machine with 10-KN force.
Results: Statistical analysis was done using student's t-test and
Lavene's test. The p-value <0.05 shows significant difference in
bond strength between A1 and A2 & B1and B2.
Conclusion: The application of a silane coupling agent to the
ceramic surface after etching with hydrofluoric acid increased
the adhesion strength with both bonding agents. Student’s
t-test revealed a significant effect of silanization. |
