In ‐office bleaching efficacy on stain removal from CAD/CAM and direct resin composite materials

ConclusionsBased on material nature, 40% hydrogen peroxide bleaching can remove staining. The new resin‐based CAD/CAM blocks showed promising results in terms of color stability.
Clinical SignificanceBleaching using 40% hydrogen peroxide can be an effective method to remove stains from dental restorations. In this way, restoration replacement as a result of discoloration may no longer be necessary.
