Özet
To examine the color stability of 3 preheated\rcomposite resins immersed in different beverages for 1, 7, and 30 days.\rMaterial and Methods: Ninety disc-shaped specimens were prepared,\r30 specimens from each of three different restorative materials\r[GrandioSO (GSO), GrandioSO x-tra (GSX), VisCalor bulk (VCB)],\rusing 8-mm diameter and 4-mm thickness molds. Each group was divided into 3 subgroups (n=10) to be immersed into beverages (red wine,\rcoffee, and distilled water). The color change values [CIEDE2000\r(?E00)] were calculated at the end of the 1st, 7th, and 30th days. Generalized linear models and multiple comparison tests with Bonferroni correction at a significance level of p<0.05 were performed for the\rcomparisons of ?E00 values. Results: Among all composite and immersion media combinations, at the end of 30 days, the most prominent color change values were observed in the GSX group immersed in\rcoffee and red wine and the VCB group immersed in red wine. For all\rcomposite groups, the lowest color change values were measured after\rimmersion in distilled water in all evaluation periods. All composite\rgroups immersed in red wine showed the color change from the 1st day,\rwhile those exposed to coffee from the 7th day, above the clinically acceptable values. Conclusion: The color change values of preheated\rresin-based composites kept in coffee and red wine were affected by the\rproperties of the immersion solution and storage times rather than the\rtype of the material.
