Amaç: Bu çalışmanın amacı belirli sürelerdefarklı içeceklerde bekletilen organik modifiye seramik (ormoser) vedimetakrilat-esaslı kompozit rezinlerin renk stabilitelerininkarşılaştırılmasıdır.Gereç ve yöntem: Bu çalışma için ikifarklı visközitede ormoser-esaslı kompozit rezinler (Admira, Admira Flow) veiki farklı dimetakilat-esaslı kompozit rezin (Valux Plus, Filtek Z250)kullanıldı. Her bir kompozitten 2 mm kalınlığında ve 8 mm çapında 20 adet örnekhazırlandı. Rastgele 4 gruba ayrılan örnekler üç farklı solüsyonda (kahve, pH5,5; kola, pH 2,51 ve kırmızı şarap, pH 3,28) ve kontrol grubu olarak distilesuda (pH:6,7) bekletildi (n=5). Renk ölçümleri, örnekler solüsyonlardabekletilmeden önce ve bekletildikten 1, 7, 15 ve 30 gün sonra spektrofotometreile yapıldı ve ΔE değerleri hesaplandı. Verilerin istatistiksel analizinde tekyönlü ANOVA ve Tukey LSD çoklu karşılaştırma testi kullanıldı. İstatistikselanlamlılık düzeyi p<0.05 olarak alındı.Bulgular: Birinci gün sonunda yalnızca kırmızışarapta bekletilen Valux Plus ve Filtek Z250 örneklerinde ΔE>3,3 bulunurken(p<0,05), 30 gün sonunda tüm örneklerde ΔE>3,3 bulundu. Tüm kompozitlerdeen yüksek renk farklılıkları kırmızı şarapta bekletilen örneklerde görülürken(p<0,05), en yüksek ortalama renk farklılıkları Filtek 250 örneklerindetespit edildi. Sonuçlar: Çalışmada kullanılan kompozitrezinlerin farklı içecekler karşısında renk değişimine hassas olduğu bulunmuş,ormoser-esaslı kompozit rezinler dışsal renklenmelere karşı daha dirençlibulunmuştur.Anahtar Kelimeler: Ormoser, dimetakrilat-esaslı kompozit rezin, renk strabilitesit COMPARISONOF COLOR STABILITY OF ORMOCER AND DIMETHACRYLATE-BASED COMPOSITE RESINS AFTER IMMERSIONIN DIFFERENT BEVERAGESABSTRACTAim: The purpose of this study was to compare the color stability of organicmodified ceramic (ormocer) and dimethacrylate-based composite resin materialsafter immersion in different beverages for a certain period.Materials and method: Two different ormocer-based composite resin (Admira, Admira Flow) withdifferent viscosity and two dimethacrylate-based composite resin (ValuxPlus, Filtek Z250) were used in thisstudy. Twenty composite resin discs (8 mm x 2 mm) were prepared from eachmaterial. Specimens were randomly divided into 4 groups and were immersed inthree staining solutions (coffee pH 5,5, cola pH 2,51, red wine pH 3,28) and distilled water for control group (n=5).Color changes were measured with a spectrophotometer at baseline and after 1,7, 15 and 30 days of immersion and ΔE values were calculated. Data were analyzed by using one-way ANOVAand post-hoc Tukey LSD. A p-value <0.05 was considered statisticallysignificant.Results: At the end of the first day, only in Valux Plus and Filtek Z250 samplesimmersed in red wine showed a ΔE value > 3.3, while at the end of 30 days inall samples ΔE was > 3.3. Among all drinks tested, maximal color change wascaused by red wine (p<0.05). The highest color differences were calculatedin Filtek Z250 samples (p<0,05).Conclusions: It can be concluded that the tested compositeresin materials were susceptible to staining with different drinks andOrmocer-based composite resins are more resistant to external discolorations.Key words: Ormocer, Dimethacrylate-based composite,Color stability
