ABSTRACT
This Study Was Conducted To Evaluate The Effect Of Pre- And Post-bleaching On The Color Change Of Resin Infiltrated Enamel Versus Sound Enamel. M&M: A Total Of 30 Bovine Specimens Were Used, On Each; 3 Windows Were Created; Window A �sound Control�, Window B �demineralized� And Window C �demineralized And Resin Infiltrated�, A Spectrophotometer Was Used To Assess Baseline Color In Each Window Then Bleaching Was Performed For All 3 Windows And Resin Infiltration Was Done For Window B Then Final Color Was Re-assessed.

Results: No Clinical Significant Difference Was Found In Color Change (?E) Of Pre- And Post-bleached Resin Infiltrated Specimens Compared To Sound Bleached. Conclusion: Pre-bleaching And Post-bleaching Resin Infiltrated Enamel Lesions Showed A Clinically Similar Color Change To Sound Bleached Enamel.
