ABSTRACT
The study was inspired by the chemical surface analysis of a pigmented ceramic sample of a clinical case, which was submitted to a surface study, by means of a chemical chromatographic and electronic microscope. We also performed an "in-vitro" quali-quantitative experiment with 200 ceramic surfaces made of lithium disilicate and feldspar. Which were divided into different surface variables. We also executed mathematical calculations in order to calculate the Delta-E-1976 indicator, which determines the difference of color in ceramic surfaces. In this sense, we analyzed the values obtained with standardized polarized photographs, before and after submerging them into different pigmentation containers for 20 days. These values were compared with visual tests. We performed the mathematical analysis by using the SPSS-22 statistical package.
