Background: The SBS is always affected by the bleaching procedures which can alter the effectiveness of bonding protocols of the restoration. Objective: This study evaluates the SBS of porcelain laminate veneers bonded to bleached enamel using two different resin cements under various conditions. Study Design: Forty maxillary central incisors were separated from their roots and attached to acrylic blocks. Specimens were assigned to four groups after bleaching: Group A (control), Group B (immediate bonding), Group C (delayed bonding), and Group D (antioxidant treatment). Each group was divided into two subgroups based on the resin cement used: Group VL (Variolink) and Group RX (Rely X). Lithium disilicate glass-ceramic discs were bonded to each group, and shear bond testing was conducted using a universal testing machine. Results: In Group A, Subgroup AVL showed a SBS of 2.95 MPa, significantly higher than Subgroup ARX, which showed 1.09 MPa (p=0.014). Subgroups BVL and BRX showed no significant difference. In Group C, Subgroup CVL exhibited a SBS of 2.87 MPa, significantly higher than Subgroup CRX, which showed 0.97 MPa (p=0.035). Subgroups DVL and DRX showed no significant difference. Conclusion: The bond strength of bleached enamel returns to normal after one week. Surface treatment with 10% sodium ascorbate is an effective alternative to delayed bonding. Variolink resin cement resulted in higher SBS compared to RelyX U200.
