Within the experimental limitations of this in-vitro study, it can be concluded that in teeth exposed to vital bleaching with 20% carbamide peroxide the application of 10% SA in an aceton-water solution prior to bonding procedures can restore compromised enamel bond strength to its unbleached state within a clinical acceptable time of 1 min. Further research is suggested to elucidate the effects of different bleaching agents and adhesive resins.
