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.

D007180	Incisor	Any of the eight frontal teeth (four maxillary and four mandibular) having a sharp incisal edge for cutting food and a single root, which occurs in man both as a deciduous and a permanent tooth. (Jablonski, Dictionary of Dentistry, 1992, p820)	Incisors
D009050	Fluorosis, Dental	A chronic endemic form of ENAMEL HYPOMINERALIZATION caused by drinking water with a high fluorine content during the time of tooth formation, and characterized by defective calcification that gives a white chalky appearance to the enamel, which gradually undergoes brown discoloration.
