Clareamento dental supervisionado : comparação de técnicas.

Abstract

The aim of this study was to indicate the effectiveness of a conventional supervised whitening method compared to the whitening technique with plastic strips impregnated with bleaching material, after carrying out a clinical evaluation. The study had the participation of three volunteer students of the Dentistry Course from the University of Santa Cruz do Sul, who presented natural teeth and healthy tooth of a second premolar and premolar ones. One of the students made use of the 10% hydrogen peroxide gel, another student used the carbamide peroxide gel at 16% and the third student the kit of plastic tape impregnated with 10% hydrogen peroxide. The effectiveness was determined through a vitta color scale and by taking pictures before the procedure, then again after two weeks, and thirty days post use of the bleaching gel. In both whitening methods some color change was noticed even with the continued intake of foods and pigmented beverages. The whitening method performed with adhesive tapes showed better results on the usage of time to reach the saturation point, two weeks being necessary to achieve the whitening effect, presenting slight sensitivity at the end of the second week. However, both patients who used the conventional method of supervised whitening with trays had the same result in regards to the saturation point, but taking twice as long, requiring thirty days to the effectiveness of whitening. In this method the patients reported greater sensitivity. However, it is clear that both methods are effective in teeth whitening.
