Özet

Introduction: The aim of this study is to evaluate the translucency and color change of two computer-aided design and computer aided manufacturing (CAD/CAM) blocks after subjected to mechanic polishing, coffee staining, and prophylactic paste polishing procedures. Methods: 26 specimens (n=13) were obtained from each CAD/CAM block (Cerasmart A2-HT; GC, Initial-LRF, A2-HT: GC). Colorchange values were evaluated after subjected to mechanic polishing, coffee staining, and prophylactic polishing procedures. Datawere analyzed by a Shapiro-Wilk normality test and the translucency and color change values were evaluated statistically withFriedman test. Mann Whitney-U test was used to determine the statistical significance between the Cerasmart and Initial-LRF interms of translucency and color change (α=.05). Results: For baseline measurements and after mechanic polishing measurement, the mean translucency value of the Cerasmartwas significantly higher than Initial-LRF (p<0.05). In Cerasmart and Initial-LRF groups, coffee storage significantly increased thecolor change value, polishing with a prophylactic paste significantly decreased the color change value (p<0.05). Discussion and Conclusion: Cerasmart, showed higher discoloration rate in coffee than Initial-LRF, and the translucency values ofboth Cerasmart and Initial-LRF specimens stored in the coffee solution decreased. Also, polishing with a prophylactic paste can berecommended.
