Amaç: Bu in vitro çalışmanın amacı, kondanse edilebilen ve yüksek dolduruculu akıcı kompozitlerin renk uyumu ve floresans özelliklerinin doğal diş dokuları ile karşılaştırmalı olarak değerlendirilmesidir. Gereç ve Yöntemler: On bir kondanse edilebilen rezin kompozit ve dört yüksek dolduruculu akıcı kompozit grupları araştırıldı. Toplam 120 örnek hazırlandı ve 24 saat distile su içinde bekletildi (n=8). Fotoğrafları çekmek için çapraz polarizasyon fotoğrafçılığı ve çapraz polarizasyon filtrelerinin floresan aydınlatmayla kombinasyonu kullanıldı. Her görüntüde bir örnek ve doğal diş yan yana yer alıyordu. Çekilen fotoğraflar üzerinden L*, a* ve b* koordinatları elde edildi, diş ve örnek arasındaki ΔE00 değeri hesaplandı. Doğal diş ve kompozit materyaller arasındaki renk uyumu ve floresans uyumu Photoshop CC yazılımı kullanılarak değerlendirildi. Veriler General Linear Model yöntemi ve Tukey HSD testleri kullanılarak istatistiksel olarak analiz edildi (p<0,05). Bulgular: Renk uyumu ve floresans uyumu verilerine göre kompozitlerin ortalama değerleri arasında fark vardır (p<0,001). Filtek grubu hariç tüm grupların renk uyumu ve floresans uyumu değerleri arasında anlamlı fark vardır. Floresans uyumu (16,76±6,05) değeri renk uyumu (5,7±2,8) değerine göre anlamlı şekilde yüksek bulundu (p<0,001). Akıcı (14,96±8,06) ve kondanse edilebilir (9,87±6,47) kompozitlerin ortalama ∆E00 değeri arasında anlamlı fark vardır (p<0,001). Sonuç: Rezin kompozit materyal ile doğal diş arasında iyi bir renk uyumu olması, her zaman iyi bir floresans uyumu olduğu anlamına gelmeyebilir. Akıcı kompozitler floresans ışık altında ışığı daha fazla yansıttıkları için, anterior bölgede vestibül yüzeyin tamamını içermeyen restorasyonlarda kullanımı sınırlı olabilir.

Objective: This in vitro study aimed to evaluate the color adjustment and fluorescence features of paste-type and flowable resin composites in comparison with the natural tooth. Material and Methods: Eleven paste-type and four flowable resin composites were investigated. A total of 120 samples were prepared and kept in distilled water for 24 hours (n=8). Cross-polarization photography and the combination of it with fluorescence illumination were used to take the photographs. In each image, one sample and an extracted tooth were included side-by-side. L* , a*, and b* coordinates were measured, and ΔE00 values between the tooth and the samples were calculated. Color adjustment and fluorescence adjustments between the natural tooth and the composite samples were assessed by using the Photoshop CC software. Data were analyzed statistically using the General Linear Model and Tukey HSD tests (p<0.05). Results: A significant difference between the composites' average color adjustment and fluorescence adjustment values was observed (p<0.001). There was a significant difference between the color adjustment and fluorescence adjustment values for all the groups except the Filtek group. The total fluorescence adjustment (16.76±6.05) values were significantly higher than the total color adjustment (5.7±2.8) values (p<0.001). A significant difference was also observed between the ∆E00 values of flowable (14.96±8.06) and paste-type (9.87±6.47) composites (p<0.001). Conclusion: A good color adjustment between the resin composite materials and natural teeth may not always indicate good fluorescence compatibility. Since the flowable resin composites were generally brighter under fluorescence illumination, the use of these materials may be limited for the anterior partial coverage restorations in patients with high esthetic expectations.
