ABSTRACT
 Objective: To examine the color stability of 3 preheated composite resins immersed in different beverages for 1, 7, and 30 days. Material and Methods: Ninety disc-shaped specimens were prepared, 30 specimens from each of three different restorative materials [GrandioSO (GSO), GrandioSO x-tra (GSX), VisCalor bulk (VCB)], using 8-mm diameter and 4-mm thickness molds. Each group was divided into 3 subgroups (n=10) to be immersed into beverages (red wine, coffee, and distilled water). The color change values [CIEDE2000 (ΔE00)] 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 comparisons of ΔE00 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 coffee and red wine and the VCB group immersed in red wine. For all composite groups, the lowest color change values were measured after immersion in distilled water in all evaluation periods. All composite groups immersed in red wine showed the color change from the 1st day, while those exposed to coffee from the 7th day, above the clinically acceptable values. Conclusion: The color change values of preheated resin-based composites kept in coffee and red wine were affected by the properties of the immersion solution and storage times rather than the type of the material.

ÖZET
 Amaç: Bu çalışma, 1, 7 ve 30 gün boyunca farklı içeceklerde bekletilen ön-ısıtma uygulanmış 3 farklı kompozit rezinin renk stabilitelerini incelemektedir. Gereç ve Yöntemler: Üç farklı restoratif materyalin [GrandioSO (GSO), GrandioSO x-tra (GSX), VisCalor bulk (VCB)] her birinden 30 örnek olmak üzere, 8×4 mm kalıplar kullanılarak 90 adet disk şeklinde örnek hazırlandı. Her bir grup, 3 farklı içecekte (kırmızı şarap, kahve ve distile su) bekletilmek üzere alt gruplara ayrıldı (n=10). Renk değişim değerleri [CIEDE2000 (ΔE00)] 1, 7 ve 30. günlerin sonunda hesaplandı. ΔE00 değerlerinin karşılaştırılmasında p<0,05 anlamlılık düzeyinde genelleştirilmiş lineer modeller yöntemi ve çoklu karşılaştırmalar için Bonferroni düzeltmesi kullanıldı. Bulgular: Otuz günün sonunda, tüm kompozit ve bekletme ortamı kombinasyonları arasında en belirgin renk değişim değerleri, kahve ve kırmızı şarapta bekletilen GSX ile kırmızı şarapta bekletilen VCB gruplarında gözlemlendi. Tüm kompozit grupları için en düşük renk değişim değerleri, tüm değerlendirme periyotlarında distile suda bekletme sonrasında ölçüldü. Tüm kompozit grupları için kırmızı şarapta bekletme 1. günden itibaren klinik olarak kabul edilebilir düzeyin üzerinde renk değişimine neden olurken, bu durum kahveye maruz kalan örneklerde 7. günden itibaren geçerliydi. Sonuç: Kahve ve kırmızı şarapta bekletilen ön-ısıtma uygulanmış rezin bazlı kompozitlerin renk değişim değerleri, materyalin tipinden çok bekletilen solüsyonun özellikleri ve bekletilme sürelerinden etkilenmiştir.
