EVALUATION OF CHANGES IN THE MICROSTRUCTURE OF THE ENAMEL OF THE RELIEF AND ITS MICRO-HARDNESS, DEPENDING ON THE IMPACT OF DIFFERENT BLEACHING SYSTEMS
This article presents the scientific and practical research, which based on the data of the pilot study proved the efficacy of diode laser in comparison with other whitening systems. Analysis bleaching systems having different concentrations of hydrogen peroxide and a source of activating a bleaching gel. The effect of the bleaching agent on the discoloration of tooth enamel caused by various etiological factors. In addition, it shows the effectiveness of bleach with a different mechanism of action, which must be considered when choosing a method of whitening. The efficacy of laser bleaching in the algorithm to eliminate discoloration of the teeth. It is shown that the relative efficiency of existing methods of whitening. It justified the present study. The results confirmed morphologically and proved in the experimental conditions.
