Abstract
It was evaluated the bleaching effect of whitening toothpastes with use associated or not of special toothbrush. Sixty-four patients were randomly divided into groups according to the bleaching treatment used (G1A: neutral fluoride gel; G1B: nightguard vital bleaching / carbamide peroxide 10%; G2: Colgate ® Branqueadora , G3: Malvatricin Branqueadora; G4: manipulated toothpaste - Phormula Ativa). The experimental groups were divided into subgroups A: Use of conventional toothbrush Oral B Indicator ® plus; B: use of special toothbrush Oral B ® Advanced Artica. The analysis of the difference of color observed initially and after four weeks of treatment using the Mann-Whitney test didn´t show significant differences (p> 0.05) when compared experimental groups with the Negative Control Group, but showed difference when compared to the Positive Control Group, with better results for the nightguard vital bleaching. The comparison between the toothbrushes used didn´t reveal statistical differences. It was possible to conclude that the toothpastes evaluated were not effective in producing a significant whitening effect; the combination with special toothbrush didnt' exercise significant statistically influence on the whitening effect of any of the products used.
