Design outcomes

Primary

MeasureTime frame
Expected closure 1:Darkening of the enamel blocks after the use of pigment solutions verified by means of analysis with the classic Vita color scale with a difference of 3.3 color in the anterior and posterior measurements of the treatment ;Expected closure 2: Increased roughness of the enamel blocks after the use of pigment solutions verified by mean roughness values (Ra) with roughness values after the intervention above 0.2um.

Secondary

MeasureTime frame
Expected closure 3 :Bleaching of the enamel blocks without exposure to pigment solutions, verified after the treatment, by means of Vita Classical color scale analysis with values of color difference of 3.3 color in the anterior and posterior measurements of the treatment;Expected closure 4: No modification of the roughness of the enamel blocks after the use of pigment solutions verified by mean roughness values (Ra) with values post intervention similar to the initial measurement.
