The purpose of this study is to evaluate the effect of bleaching on the bond strength of ceramic laminate veneers (E.max press) to bleached enamel using two adhesive resin cements with different modes of curing:
Rely X Ultimate (dual cure).
Variolink N (light cure).
E.max Discs were cemented to prepared enamel teeth surfaces at different time intervals tested :
E.max discs were cemented to the prepared enamel teeth surfaces immediately after bleaching.
E.max discs were cemented to the prepared enamel teeth surfaces 2 week after bleaching
