Abstract
This study was performed to evaluate the effect of themal changes on the shear bond strength of one total-etch adhesive and two self-etch adhesives to ground enamel .A total of thirty-six extracted sound human molars were selected for the study. The root portion of each tooth was removed and crown of each tooth was sectioned mesio-distally , The sectioned crowns were embedded in a self-curing acrylic resin with the buccal or lingual surfaces positioned for surface treatment and composite blacement.The enamel surfaces were ground flat with 600-grit Silicon Carbid papers,to obtain flat enamel surface.
