Abstract

Background and Aim: The aim of this study was to evaluate the effects of laser-assisted in-office bleaching on the surface roughness of three types of resin composite materials.Materials and Methods: Three types of resin composites (Ceram-X Mono, Filtek Silorane, Tetric EvoCeram Bulk Fill) were used for the study. A total number of ten samples measuring 9mm in diameter X 2mm thick were prepared from each one of the restorative materials. The samples were bleached with 35% hydrogen peroxide gel (LaserWhite20) with diode laser (Epic, 940nm) at 7 Watts in continuous mode. The roughness of the specimens (Ra, ?m) was measured before and immediately after the bleaching procedure using a surface profilometer. Data were analyzed using KruskalWallis and Wilcoxon tests.Results: There were no significant differences in roughness values among the groups before the bleaching procedures (p>0.05). After bleaching, significant differences were observed between Ceram-X Mono and Tetric EvoCeram Bulk Fill (p<0.05).Laser-assisted in-office bleaching significantly increased only the surface roughness of Ceram-X Mono (p<0.05). The results showed no difference in Ra values of Filtek Silorane and Tetric EvoCeram Bulk Fill after bleaching (p>0.05).Conclusion: An increase in surface roughness was reported only in nanoceramic resin composite, Ceram-X Mono following bleaching. The effect of laser-assisted in-office bleaching on surface roughness was found to be material dependent.

Özet

Amaç: Bu çalışmanın amacı lazerle yapılan ofis tipi beyazlatmanın üç farklı türdeki kompozit rezinlerin yüzey pürüzlülüğüne etkisini değerlendirmektir.Gereç ve Yöntem: Bu çalışmada üç tür kompozit rezin (Ceram-X Mono, Filtek Silorane, Tetric EvoCeram Bulk Fill) kullanıldı. Her restoratif materyalden on adet 9mm çapında 2mm kalınlığında örnekler hazırlandı. Örnekler, %35'lik hidrojen peroksit jel (LaserWhite 20) ile 7 Watt gücünde sürekli moddaki diyot lazer (Epic, 940nm) kullanılarak beyazlatma işlemine tabi tutuldu. Örneklerin pürüzlülüğü (Ra, ?m) beyazlatma işlemi öncesi ve sonrasında yüzey profilometresi ile ölçüldü. Elde edilen veriler Kruskal-Wallis ve Wilcoxon testleri ile analiz edildi.Bulgular: Beyazlatma işlemi öncesinde grupların pürüzlülük değerleri arasında anlamlı bir farka rastlanılmamıştır (p>0.05). Beyazlatma sonrasında ise Ceram-X Mono ve Tetric EvoCeram Bulk Fill arasındaki fark istatistiksel olarak anlamlı bulunmuştur (p 0.05).Sonuç: Beyazlatma sonrasında sadece nanoseramik kompozit olan Ceram-X mono örneklerinin yüzey pürüzlülüğünde artış görülmüştür. Lazerle yapılan ofis tipi beyazlatmanın yüzey pürüzlülüğüne etkisi materyale göre değişim göstermektedir.
