title: [Clinical evaluation of two tooth bleaching techniques].
abstract: The purpose of this paper was to assess the clinical ability of two bleaching techniques. Patients with at least one darkened teeth caused by mechanical injuries or imperfection in the endodontic therapy were included in this study. The first step was to take an initial photography. After that the teeth were subjected to the bleaching procedures. The techniques employed were proposed by NUTTING & POE or LACERDA et alii. The assessments were made by three trained examiners using the initial and final pictures. The scores were attributed according to the color of the teeth. The data were submitted to the statistical analysis, when was possible to verify that both techniques were equally effective.
