Özet:

 Purpose: The objective of this study was to investigate the color changes of various computeraided designcomputer-aided manufacturing CADCAM materials polished with different polishing systems and immersed in various colored drinks. Materials and Methods: Three different resin-based CADCAM blocks Cerasmart, Coltene Brilliant Crios, and SHOFU Block HC were utilized. A total of 540 CADCAM blocks were prepared with a thickness of 2 mm and categorized into three main groups based on the polishing systems employed. The Sof-Lex, Identoflex, and Coltene Diatech polishing systems were administered to the materials. Subsequently, the specimens were further subdivided into three subgroups and immersed in three different colored solutions for one hour twice a day for 15 days. Filter coffee, cola, and distilled water served as the coloring agents. Color measurements were conducted at baseline and on Days 1, 7, and 15 using the VITA Easyshade compact spectrophotometer device. Results: By the end of Day 15, Cerasmart specimens exhibited the least color change when immersed in coffee and distilled water, whereas Coltene specimens demonstrated the least color change when subjected to cola. Irrespective of the CADCAM blocks and polishing systems utilized, a statistically significant difference was observed among the beverages p0.001. Particularly, coffee induced a more pronounced color change compared to the other beverages p0.001. Conclusion: The ΔE value increases proportionally with the duration of immersion in colored drinks. Specimens immersed in coffee displayed the highest color change for each CADCAM material.
