ABSTRACT
Introduction:
Thermocycling is an in-vitro process; it may affect the bonding strength between tooth and resin which is depending upon the adhesive system. Aim andObjectives:
To evaluate and compare the thermocycling effect on shear bond strength of RelyX Unicem and G-CEM Linkace to polyether ether ketone (PEEK) surface. Materials andMethods:
A total of 40 PEEK disk-shaped specimens were fabricated with dimensions of 10 × 3 mm and randomly allocated into two groups. Group A was cemented with Rely X Unicem material and Group B was cemented with G-CEM Linkace. About 10 specimens from each group were thermocycled 500 times at 5°C and 55°C. By applying force at the speed of 1 mm/min using a universal testing machine, shear bond strength was measured.Results:
The mean bond strength was compared using paired t test. There was a significant difference even before and after thermocycling.Conclusion:
In this experiment, Shear bond strength (SBS) of G-CEM Linkace showed more even before and after thermocycling when compared to RelyX. Also bond strengths of two cements decreased after thermocycling.
