title: Toothbrush abrasion of color-corrective porcelain stains applied to porcelain-fused-to-metal restorations.
abstract: Normal toothbrushing with a common dentifrice has the ability to wear away color-corrective porcelain stains applied to the surface of porcelain-fused-to-metal restorations in as few as 10 to 12 years unless a protective layer of clear glaze is applied over the stain. The additional layer of clear glaze more than doubled the time required to abrade the stain from the surface.
