ABSTRACT
 Objective: To evaluate the effect of energizing, body resistance-increasing, immune-boosting beverages, multivitamin effervescent, black tea on the color of three bis-acrylic resin composite (BRC) and one computer aided design-computer aided manufacturing (CAD/CAM) polymethyl methacrylate (PMMA) material. Material and Methods: 168 rectangular specimens (2 mm thick) were prepared in (i) BRC1 (Oratemp), (ii) BRC2 (PrimmaArt), (iii) BRC3 (Hexa-Temp), (iv) PMMA (Eray PMMA Disc) (n=42). After baseline color measurements, the specimens were immersed in various beverages. On the 1st, 14th, 28th days, color measurements were repeated. Discolorations were calculated by CIEDE2000 and CIELAB formulas and analyzed by variance and Bonferroni tests (α=0.05). Results: The ΔEab and ΔE00 results of material, beverage and material-beverage pair at days 1, 14 and 28 were statistically significant (p<0.001). After 14 and 28 days, the highest discoloration was in BRC3-black tea (ΔE00=4.4, ΔEab=6.9) and the lowest in PMMA-immune-boosting beverage with Sambucus Nigra (ΔE00=0.7, ΔEab=1.5) (p<0.05). PMMA was more resistant to discoloration than BRCs. The magnitude of discoloration for BRCs was BRC2 (ΔE00=2.3, ΔEab=4.0)>BRC3 (ΔE00=2.0, ΔEab=3.8)>BRC1 (ΔE00=1.5, ΔEab=2.6) (p<0.0001). Conclusion: Black tea and multivitamin may discolor the interim restorations more than energizing, body resistance-increasing, immune-boosting beverages. Regardless of the time point, CAD/CAM PMMA was more resistant to discoloration than tested bis-acrylic resin composites (p<0.005). Regardless of the time point, distilled water was more resistant to discoloration than tested other beverages (p<0.0001).

ÖZET
 Amaç: Bu çalışmanın amacı, enerji verici, vücut direncini artırıcı, bağışıklık sistemini güçlendirici içeceklerin, multivitamin efervesanın, siyah çayın üç bis-akrilik rezin kompozit (BRC) ve bir bilgisayar destekli tasarım/bilgisayar destekli üretim (CAD/CAM) polimetil metakrilat (PMMA) materyalinin rengine etkisini değerlendirmektir. Gereç ve Yöntemler: 168 dikdörtgen numuneler (2 mm kalınlığında) hazırlandı: (i) BRC1 (Oratemp), (ii) BRC2 (PrimmaArt), (iii) BRC3 (Hexa-Temp), (iv) PMMA (Eray PMMA Disk) (n=42). Başlangıç renk ölçümlerinden sonra, numuneler çeşitli içeceklere daldırıldı. 1., 14. ve 28. günlerde renk ölçümleri tekrarlandı. Renk değişimleri CIEDE2000 ve CIELAB formülleri ile hesaplandı ve ANOVA ve Bonferroni kullanılarak analiz gerçekleştirildi (α=0.05). Bulgular: Materyal, içecek ve materyal-içecek çiftinin 1, 14 ve 28. Günlerdeki ΔEab ve ΔE00 sonuçları istatistiksel olarak anlamlıydı (p<0,001). 14 ve 28 gün sonra, en yüksek renk değişikliği BRC3-siyah çayda (ΔE00=4,4, ΔEab=6,9) ve en düşük PMMA-Sambucus Nigra'lı bağışıklık kuvvetlendirici içecekte (ΔE00=0,7, ΔEab=1,5) görüldü (p<0,05). PMMA, BRC'lere göre renk bozulmasına karşı daha dirençliydi. BRC'ler için renk değişiminin büyüklüğü BRC2 (ΔE00=2,3, ΔEab=4,0)>BRC3 (ΔE00=2,0, ΔEab=3,8)>BRC1 (ΔE00=1,5, ΔEab=2,6) şeklindeydi (p<0,0001). Sonuç: Siyah çay ve multivitamin ara restorasyonların rengini, enerji veren, vücut direncini artıran, bağışıklık sistemini güçlendiren içeceklerden daha fazla etkiledi. Zaman noktasından bağımsız olarak CAD/CAM PMMA, test edilen bis-akrilik rezin kompozitlere göre renk değişimine karşı daha dirençliydi (p<0,005). Zaman noktasından bağımsız olarak, distile su renk değişimine karşı test edilen diğer içeceklerden daha dirençliydi (p<0,0001).
