INFLUENCE OF HOME AND OFFICE BLEACHING AGENTS ON COLOR AND TRANSLUCENCY OF COMPOSITE RESINS

INFLUENCE OF HOME AND OFFICE BLEACHING AGENTS ON COLOR AND TRANSLUCENCY OF COMPOSITE RESINS ABSTRACT: Aim: The purpose of this in-vitro study was to assess the effect of two bleaching agents on the color and translucency of aged composite resin materials (Filtek Z250, Estelite Flow Quick, and Tetric N-Ceram), as compared to re-polishing. Material and Methods: Thirty composite discs from each material were made using circular molds, and were subjected to a thermocycling process for 5000 cycles, then immersed in the prepared staining solution. The aged samples were randomly divided into three treatment groups: re-polishing, 16% carbamide peroxide (Opalescence), or 35% hydrogen peroxide (Whiteness HP). After aging and whitening treatments, the color reading was performed via a spectrophotometer. Color change (ΔE00) and translucency parameters were calculated. Data were evaluated by two-way ANOVA and Tukey’s test (p < 0.05). Results: Bleaching agents produced significantly higher color change in composite resins compared to re-polishing (p < 0.05). Bleaching agents caused similar color change in each composite resin, but carbamide peroxide caused significantly higher color change in Filtek Z250 than hydrogen peroxide. Bleaching increased significantly the translucency of all aged composite resins. When bleaching agents were compared to re-polishing, only carbamide peroxide significantly increased the translucency of Filtek Z250. The re-polishing treatment did not significantly affect the translucency of Filtek Z250 and Estelite Flow Quick, whereas the translucency of Tetric N-Ceram significantly increased. Conclusions: The applied treatments generated clinically perceptible whitening. The performance of bleaching agents was higher than that of re-polishing. The effect of bleaching agents on the translucency of composite resins depended on the material used and the treatment applied.

Gereç ve Yöntem: Silindirik kalıplar kullanılarak her bir kompozit materyalden 30 adet silindir örnek hazırlandı. Örnekler 5000 kez termal döngüye maruz bırakıldı, daha sonra renklendirici solüsyonda bekletildi. Yaşlandırılmış örnekler rastgele 3 tedavi grubuna ayrıldı; re-polisaj, %16 karbamit peroksit (Opalescence), ve %35 hydrojen peroksit (Whiteness HP). Renk ölçümü yaşlandırma ve beyazlatma tedavilerinden sonra spektrofotometre ile gerçekleştirildi. Renk değişimi (ΔE00) ve translüsentlik parametreleri hesaplandı. Veriler iki yönlü ANOVA ve Tukey’s testi ile değerlendirildi (p < 0.05). Bulgular: Beyazlatma ajanları re-polisaj işlemi ile karşılaştırıldığında önemli derecede yüksek renk değişikliği oluşturdu. Beyazlatma ajanları her bir kompozit rezinde benzer renk değişikliğine sebep oldu, yalnızca Filtek Z250 de karbamit peroksit hidrojen peroksitten yüksek renk değişikliği sağladı. Beyazlatma ajanları re-polisaj işlemi ile karşılaştırıldığında yalnızca karbamit peroksit Filtek Z250’nin translüsentliğini önemli derecede artırdı. Re-polisaj işlemi Tetric N-Ceram’ın translüsentliğini artırmasına karşın, Filtek Z250 ve Estelite Flow Quick’in translüsentliğini etkilemedi.
