INFLUENCE OFHOME AND OFFICE BLEACHING AGENTS ON COLOR AND TRANSLUCENCY OF COMPOSITE RESINSABSTRACT: Aim: The purpose of this in-vitro study was toassess the effect of two bleaching agents on the color and translucency of agedcomposite resin materials (Filtek Z250, Estelite Flow Quick, and Tetric N-Ceram),as compared to re-polishing. Material andMethods: Thirty composite discs from each material were madeusing circular molds, and were subjected to a thermocycling process for 5000cycles, then immersed in the prepared staining solution. The aged samples were randomlydivided into three treatment groups: re-polishing, 16% carbamide peroxide(Opalescence), or 35% hydrogen peroxide (Whiteness HP). After aging andwhitening treatments, the color reading was performed via a spectrophotometer.Color change (ΔE00) and translucency parameters were calculated. Datawere evaluated by two-way ANOVA and Tukey’s test (p < 0.05).Results: Bleaching agents produced significantly higher colorchange in composite resins compared to re-polishing (p < 0.05). Bleachingagents caused similar color change in each composite resin, but carbamideperoxide caused significantly higher color change in Filtek Z250 than hydrogenperoxide. Bleaching increased significantly the translucency of all agedcomposite resins. When bleaching agents were compared to re-polishing, only carbamideperoxide significantly increased the translucency of Filtek Z250. The re-polishingtreatment did not significantly affect the translucency of Filtek Z250 and EsteliteFlow Quick, whereas the translucency of Tetric N-Ceram significantly increased.Conclusions: The applied treatments generated clinicallyperceptible whitening. The performance of bleaching agents was higher thanthat of re-polishing. The effect of bleaching agents on the translucency ofcomposite resins depended on the material used and the treatment applied.Keywords: Tooth bleaching, Color, Composite resins, PolishingKOMPOZİTREZİNLERİN RENK VE TRANSLÜSENTLİĞİNDE EV VE OFİS BEYAZLATMA AJANLARININ ETKİSİ ÖZAmaç: Bu çalışmanın amacı, yaşlandırılmışkompozit rezinlerin renk ve translüsentliğinde iki farklı beyazlatma ajanınınetkisini re-polisaj işlemi ile karşılaştırmalı olarak değerlendirmektir.Gereç ve Yöntem: Silindirik kalıplar kullanılarakher bir kompozit materyalden 30 adet silindir örnek hazırlandı. Örnekler 5000 keztermal döngüye maruz bırakıldı, daha sonra renklendirici solüsyonda bekletildi.Yaşlandırılmış örnekler rastgele 3 tedavi grubuna ayrıldı; re-polisaj, %16 karbamitperoksit (Opalescence), ve %35 hydrojen peroksit (Whiteness HP). Renk ölçümüyaşlandırma ve beyazlatma tedavilerinden sonra spektrofotometre ilegerçekleştirildi. Renk değişimi (ΔE00) ve translüsentlikparametreleri hesaplandı. Veriler iki yönlü ANOVA ve Tukey’s testi iledeğerlendirildi (p < 0.05).Bulgular: Beyazlatma ajanları re-polisaj işlemiile karşılaştırıldığında önemli derecede yüksek renk değişikliği oluşturdu. Beyazlatmaajanları her bir kompozit rezinde benzer renk değişikliğine sebep oldu, yalnızcaFiltek Z250 de karbamit peroksit hidrojen peroksitten yüksek renk değişikliğisağladı. Beyazlatma ajanları re-polisaj işlemi ile karşılaştırıldığında yalnızcakarbamit peroksit Filtek Z250’nin translüsentliğini önemli derecede artırdı. Re-polisajişlemi Tetric N-Ceram’ın translüsentliğini artırmasına karşın, FiltekZ250 ve Estelite Flow Quick’in translüsentliğini etkilemedi.
