Bleaching and enamel microabrasion techniques are conservative, and provide highly satisfactory results,
without excessive wear of sound dental. They may be used in cases of TFI = 1-2 and TFI = 1-4, respectively
(27). Some authors (28,29) described the association of both techniques (microabrasion and bleaching) in cases
of TFI = 1-4. Firstly, microabrasion is carried out, and in the next appointment, the bleaching. Those authors concluded
that the whole technique provides regularization, planning and recovery of the standard color.
