Introduction: Thermocycling is an process; it may affect the bonding strength between tooth and resin which is depending upon the adhesive system.
Aim And Objectives: 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 And Methods: A total of 40 PEEK disk-shaped specimens were fabricated with dimensions of 10 × 3 mm and randomly allocated into two groups.
