Overview

Experimental analysis shows that catalysts enhance esthetics and minimize enamel damage in teeth, indicating potential benefits of combined treatments.

Key Points

  • GTL treatment significantly improved chromatic change (ΔE00) but had similar results to G45 after 15 minutes.
  • Hydrogen peroxide diffusion was 69% lower with enzyme treatment compared to conventional methods.
  • Microhardness and surface roughness remained stable in GT and NC groups, unlike G45 which showed significant deterioration.
  • Combined treatment strategies reduced enamel alterations while achieving comparable esthetic outcomes in less time.
