ÖZET
Amaç: Bu çalışmanın amacı, iki farklı bitirme-cila sistemi kullanıldıktan sonra iki farklı yüzey örtücü uygulanan bir supra-nano-dolduruculu kompozit rezinin renk stabilitesini değerlendirmektir. Gereç ve Yöntemler: Standart boyuttaki (8mm çap, 2mm yükseklik) kalıplar aracılığıyla 60 adet disk şeklinde kompozit örneği (Estelite Sigma Quick, Tokuyama, A2 renk) elde edildi. Örnekler, uygulanan cila prosedürüne göre rastgele 6 gruba ayrıldı (n=10): OD=Optidisc (Kerr), ODB=Optidisc+Biscover LV (Bisco), ODP=Optidisc+PermaSeal (Ultradent), SS=Super-Snap-Rainbow-Kit (Shofu), SSB=Super-Snap Rainbow Kit+BisCover LV, SSP=Super-Snap Rainbow Kit+PermaSeal. CIE L*a*b* sistemini kullanan bir spektrofotometre (Easy Shade, Vita) aracılığıyla ilk renk ölçümleri gerçekleştirildi ve değerler (L*a*b*) kaydedildi. Daha sonra her örnek günde 4 saat süreyle çözülebilir kahvede (Nescafe, Nestle), sonraki 20 saatlik sürede ise distile suda bekletildi. Renk ölçümleri 2., 7. ve 90. günlerde tekrarlandı. Renk değişimleri ΔE*=[(ΔL*)2+(Δa*)2+(Δb*)2]½ formülüne göre hesaplandı. Verilerin istatistiksel analizinde Kruskal Wallis ve Mann-Whitney-U testleri kullanıldı. İstatistiksel anlamlılık düzeyi p3,3) gözlendi. Doksan günlük süre sonunda SS ve ODB grupları arasında istatistiksel olarak anlamlı farklılık bulunmazken (p>0,05), diğer tüm gruplar arasında istatistiksel olarak anlamlı farklılık tespit edildi (p3,3) gözlenirken yalnızca SS grubunda klinik olarak kabul edilebilir (ΔE≤3,3) düzeyde renk değişimi tespit edildi. En yüksek renk değişim değeri (ΔE*), PermaSeal yüzey örtücü uygulanan gruplarda gözlendi (p>0,05). Sonuç: PermaSeal yüzey örtücü supra-nano dolduruculu rezinin renk stabilitesini olumsuz etkilemiştir. Biscover LV yüzey örtücünün kompozit rezinlerin renk stabilitesine etkisini inceleyen daha kapsamlı çalışmalara ihtiyaç vardır.

ABSTRACT
Objective: The aim of this study was to evaluate the color stability of a supra-nano-filled composite resin after treating with two different finishing/polishing systems and surface sealants, respectively. Meterial and Methods: Sixty composite discs (Estelite Sigma Quick, Tokuyama, A2 shade) were prepared using Standard cylindrical molds (8mm diameter, 2mm height) and randomly divided into 6 groups (n=10) according to polishing procedures: OD=Optidisc (Kerr), ODB=Optidisc+Biscover LV (Bisco), ODP=Optidisc+ PermaSeal (Ultradent), SR=Super-Snap-Rainbow-Kit (Shofu), SSB=Super-Snap-Rainbow-Kit+BisCover LV, SSP=Super-Snap- Rainbow-Kit+PermaSeal. Baseline color measurements were performed using a spectrophotometer (Easy Shade, Vita) based on CIE (L*a*b*) color system and the mean data (L* a* b*) was recorded. Afterwards, each specimen was immersed within instant coffee (Nescafe, Nestle) for 4h and then within distilled water for the next 20h-per-day. The color measurements were repeated following 2., 7. and 90. days. Color difference (ΔE*) was calculated based on CIE (L*a*b*) formula. Data were assessed with Kruskal Wallis and Mann- Whitney-U tests statistically. A p-value <0.05 was considered statistically significant. Results: The findings in the 2. and 7. days revealed that Permaseal-applied groups, ODP and SSP, exhibited a clinically unacceptable level of color change (ΔE>3.3). Considering the 90 day results; significant differences were observed between groups (p<0.05) except SS and ODB (p>0.05). However all sealant applied groups exhibited clinically unacceptable level of color change (ΔE>3.3). Only the level of color change in SS was clinically acceptable (ΔE≤3.3). PermaSeal applied groups exhibited the highest color change (ΔE*) values among all groups tested (p<0.05). Conclusion: PermaSeal surface sealent negatively affected the color stability of the supra-nano resin composite. Further studies investigating the effect of Biscover LV on color stability of supra-nano resin composite are needed.
