Description:This study examined the effects of peroxide tooth bleaching, including Crest Whitestrips hydrogen peroxide treatments, on the fracture susceptibility and surface morphology of human tooth enamel in vitro. Extracted human molars were ground and polished to prepare a uniform substrate for bleaching treatments. A cycling treatment methodology was employed which alternated ex vivo human salivary exposures with bleaching treatments under conditions of controlled temperature and durations of treatment. Bleaching treatments included commercial Crest Whitestrips bleaching gels, which utilize hydrogen peroxide as the in situ bleaching source, and several commercial carbamide peroxide bleaching gels. Control treatments included placebo gels and an untreated group.
