ÖZET
 Amaç: Bu çalışmanın amacı, 2 farklı kompozit rezin örneklerinin 3 farklı zaman diliminde farklı içeceklerde bekletilmesiyle kompozit rezinlerde meydana gelen renk ve translusenstlik değişimin değerlendirilmesidir. Gereç ve Yöntemler: Bu çalışmada, 2 farklı kompozit rezin kullanıldı: Universal nanohibrit kompozit Palfique Omnichroma (OMN) ve nanohibrit kompozit Estelite Sigma Quick (ESQ). Kompozitlerin renk stabilitesini değerlendirmek için A1, B2 ve C3 olmak üzere 3 farklı renkte ESQ kompozit ve tek renkli OMN kompozit kullanıldı. Her materyal için 90 adet silindirik örnek (2 mm kalınlık, 6 mm çap) hazırlandı. Başlangıç renk ölçümleri alındıktan sonra örnekler distile su, kırmızı şarap ve kahve gibi farklı içeceklerde bekletildi. Devamında sırasıyla 24 saat, 1 hafta ve 1 ay sonra ölçümler yapıldı. Tüm renk ölçümleri, klinik bir spektrofotometre ile CIEDE2000 renk koordinatlarına göre yapıldı. Translusentlikte meydana gelen değişiklikleri değerlendirmek için translusentlik parametresi (TP) kullanıldı. Verilerin normalliğini analiz etmek için Kolmogorov-Smirnov testi kullanıldı. Farklı solüsyonlara daldırılan örneklerin ΔE00 ve ΔTP değerleri arasındaki farklar bağımsız örneklem t-testi, tek yönlü varyans analizi ve Tukey dürüst anlamlı fark post-hoc testleri ile analiz edildi. ΔE00 ve TP değerlerinin zamana bağlı değişimlerini belirlemek için tekrarlı varyans analizi testi kullanıldı. Bulgular: Her iki kompozitin A1 ve B2 renkli örneklerinin distile su ve diğer renklendirici sıvılarda aynı süre bekletilmesi sonucunda ∆E değerleri arasında istatistiksel olarak anlamlı fark tespit edildi (p<0,05). Sonuç: Renklendirici içecekler, kompozitlerin fizikokimyasal özelliklerinden bağımsız olarak her iki kompozit rezinde de renklenmeye neden olmuştur. Her iki nanohibrit kompozitte de tüm zaman dilimlerinde renklendirme sıvılarında meydana gelen renk değişimi arasında fark yoktur.

ABSTRACT
 Objective: The aim of this study is to evaluate the color and translucency changes that occur in composite resins by keeping 2 different composite resin samples in different beverages for 3 different time periods. Material and Methods: Two resin-based composites were used in present study: an universal nanohybrid composite Palfique Omnichroma (OMN), and a nanohybrid resin Estelite Sigma Quick (ESQ). In order to evaluate the color stability of the composites, ESQ composite in 3 different colors, A1, B2 and C3, and single color OMN composite were used. Ninety cylindrical specimens were prepared for each material (2 mm in thickness, 6 mm in diameter). After the baseline color measurements were taken, the samples were kept in different beverages such as distilled water, red wine and coffee. After baseline measurements, 24 hours, 1 week and 1 month measurement were taken respectively. All color measurements were performed according to the CIEDE2000 color coordinates with a clinical spectrophotometer. The translucency parameter (TP) was used to evaluate changes in translucency. The Kolmogorov-Smirnov test was used to analyze the normality of the data. Differences between ΔE00 and ΔTP values of samples immersed in different solutions were analyzed by independent samples t-test, one-way analysis of variance and Tukey honest significance test post-hoc tests. Repeated measure analysis of variance test was used to determine the time dependent changes of ΔE00 and TP values. Results: A statistically significant difference was found between ∆E values as a result of keeping the A1 and B2 colored samples of both composites in distilled water and other coloring beverages for the same time (p<0.05). Conclusion: Coloring beverages caused coloration in both composite resins, independent of the physicochemical properties of the composites. In both nanohybrid composites, there is no difference between the discoloration that occurs in the coloring beverages over all time periods.
