[Scanning electronic microscopy analysis of the effect of bleaching solutions on fluorosed enamel].
The authors observed the bleaching of fluorosed human teeth with scanning electronic microscope (SEM). They found that the essence of the bleaching is the demineralization caused by the hydrochloric acid in the bleaching solutions. Physical grinding of the surface of the fluorosed enamel can accelerate the penetration of the solutions into enamel and shorten the bleaching time. The authors also observed the ultrastructural changes caused by the bleaching, and pointed out that the treatment of the bleached enamel surface is very important.
