Assessment of Surface Topography and Microhardness of Acrylic Resins and a Bisacrylic Resin Submitted to Different Polishing Techniques
Introduction: Acrylic resins are indicated mainly for making temporary restorations fixed partial denture. This work aims to verify the influence of different polishing systems on the surface topography and microhardness of three acrylic resins: Dencôr, Dencrilay Speed, Duralay and a bisacrylic resin: Proviplast.
Methodology: 140 specimens were made with a cylindrical silicone matrix of dimensions 5 x 2 mm (ISO 4872) that were distributed in fourteen test groups, according to the polishing (n: 10): ecs - Silicon Carbide brush, pbd - rubber tips impregnated with diamond, pd - paste diamond and GL: application of glaze. The roughness (Ra), Atomic Force Microscopy (mfa) and Microhardness (Ma) were obtained before and after polishing performed with the described systems.
Results: The data obtained in the study were tabulated and analyzed by anova and Student’s “t” test 5% (α = 0.05). The roughness values varied between 0.05 and 6.2 μm and the bisacrylic resin with glaze presented the lowest average of roughness (0.05) and Dencrilay without polishing presented the highest value (6.2). The microhardness values varied between 23.3 and 11.6 where Duralay with abrasive rubber presented the highest average microhardness (23.3) and Duralay with paste the lowest value (11.6). Among the tested materials, resin bisacrylic with glaze obtained the lowest surface roughness value and Duralay resin with rubber obtained the highest microhardness value.
