520			_aThe aim of this study was to investigate the effect of two different bleaching procedures , home and in - office bleaching using Whitesmile products on enamel ultrastructure , the microhardness of human treated enamel and the color of teeth . Twenty extracted sound and healthy human premolars were collected . Since they may differ in many properties as the enamel thickness , there was standardization through the use of the same tooth to be investigated before and after bleaching
