Color stability of bleached tooth enamel brushed with different stain-removing toothpastes.

Objective: The effects of four toothpastes on the color stability of in-office bleached tooth specimens were determined.

Materials And Methods: We evaluated an experimental toothpaste (EXP) and three commercially available toothpastes: Colgate Optic White (OPW), Aquafresh White & Protect (AWP), and Crest 3D White (CDW). OPW, AWP, and CDW contained inorganic abrasives, whereas EXP and AWP contained sodium polyphosphate.

Ultraphosphate, a potent stain control agent that is effective for both stain removal and prevention of stain deposition.

Polyphosphate is a phosphate polymer which is effective for stain removal and prevention of stain deposition. Ultraphosphate belongs to the polyphosphate group and has a highly branched mesh-like structure. To evaluate stain control ability of ultraphosphate, we used HAP powder, glass-ionomer cement and detached human teeth for models of in vitro stain control experiments.
