This in-vitro study aims to evaluate the surface roughness and coloration of four different CAD/CAM ceramic materials applied with different finishing and polishing sets. In this study, the surface roughness of IPS e. Max (EX), Shofu Block HC (SH), VITA Enamic (EN), GC Cerasmart (CS) materials were measured before and after the use of the Ceramaster Coarse Assorted-Ceramaster Assorted-Dura polish DIA (CCA-CA-DPD), GZ Eve Diapol (ED), Optrafine (OF), Vita Enamic (VE) polishing sets. The material specimens were kept in coffee solution at 37 ° C for 60 days to examine their coloration. The colors of the specimens were measured at the beginning and then 7, 14, 30 and 60 days of immersion in solution. The obtained roughness and ΔE data were evaluated according to the material and polishing sets. The significance of the change in coloration and roughness over time; for each material/polishing set, the analysis of whether the change in coloration and roughness over time is similar between the material/polishing set types and whether there is a significant difference between material/polishing sets were examined by two-way repeated measures analysis of variance. Kolmogorof-Simirnof goodness of fit test was used to test whether the change of coloration and roughness values over time was normal or not. Differences between materials/polishing sets were determined using the Tamhane Multiple Comparison test. How the changes over time changed between the material/polishing sets were graphically explained. Pearson's correlation coefficient was used to determine the relationship between coloration and roughness, and the relationship was shown with scatter plots. p<0.05 was taken as the limit of significance in all statistical tests. The difference between the roughness values obtained by using OF and VE for EX was significant (p <0.05). When VE was applied to EX, the surface roughness remained above the natural enamel roughness. The color change values obtained from applying OF to EX were significantly lower than all other sets (p <0.05) and remained below the clinically acceptable threshold value.
