MeasureTime frame
The expected outcome 1: Whitening of the patients teeth after the whitening treatment, whichever technique is used, verified by means of Vita Classical color scale analysis with values of color differences in the post treatment measurements.

Secondary

MeasureTime frame
Expected outcome 2: Decreased calcium and phosphorus concentration of dental enamel after the use of bleaching agents, verified by micro-enamel of dental enamel and analysis of microbiopsy done in X-ray fluorescence.
