Pode a pigmentação extrínseca de cerâmicas odontológicas causar significativas alterações na rugosidade e no acumulo de biofilme?

Abstract

CAD/CAM monolithic ceramic restorations are milled from monochromatic blocks, which generally require extrinsic characterization/pigmentation, popularly known as stain. However, it is suspected that this technique can change the topography of the ceramic material. In view of this, this study aimed to review the literature about possible changes in the surface of dental ceramics, such as roughness and biofilm formation, after stain application. The PICO strategy was then adopted to carry out this literary review: laboratory studies were included whose population (P) was composed of dental ceramics, which had as intervention (I) the application of “stain/extrinsic characterization” and/or glaze, compared (C) to ceramics without stain and/or glaze and the outcome (O) being the observation of the surface properties. Pubmed, Medline, Web of Science, Scopus, LILACS, Scielo and gray literature databases were used between January and February 2020. Clinical studies, in vivo studies, literature cases or studies that did not meet the PICO criteria were excluded. With this, it is concluded that the makeup and/or glaze used to characterize monolithic dental restorations in ceramics can cause an increase in surface roughness and bacterial adhesion to the surface of the same.
