Abstract

Amaç: Bu çalışmanın amacı %20 karbamid peroksit içeren evde uygulanan beyazlatma ajanının, bir nanofil, bir nanoseramik, bir mikrohibrit kompozit rezinin yüzey pürüzlülüğüne etkisinin incelenmesidir. Gereç ve Yöntem: materyallerden (Filtek Supreme XT, Ceram-X Mono, Aelite All Purpose Body) 42’şer adet örnek elde edilerek rastgele iki gruba ayrılmıştır (n=21). Bir gruba Opalescence PF %20 8 gün boyunca günde 6 saat uygulanırken, diğer grup örnekler distile suda saklanmıştır. Tüm örneklerin yüzey pürüzlülüğü değerleri (Ra) profilometre ile ölçülmüştür. Elde edilen veriler Kruskal Wallis testi ve Wilcoxon İşaret testi ile istatistiksel olarak analiz edilmiştir (p

EFFECT OF CARBAMIDE PEROXIDE BLEACHING AGENT ON SURFACE ROUGHNESS OF RESIN COMPOSITES

Abstract

Objective: The aim of the study was to evaluate the effect of 20% carbamide peroxide home bleaching agent on surface roughness of a nanofil, nanoceramic and microhybrid resin composite. Material and methods: 42 specimens were prepared from each restorative material (Filtek Supreme XT, Ceram-X Mono, Aelite All Purpose Body) which were then randomly divided into two groups (n=21). While in the first group Opalescence PF %20 was applied for 6 hours for 8 days, the other group was stored in distilled water. Surface roughness values (Ra) were measured for all specimens. Data were analyzed using Kruskal Wallis test and Wilcoxon signed rank test (p<0.05).
Results: There was no statistically significant difference among surface roughness values of bleached and non-bleached Aelite All Purpose Body (p=0.243), Ceram-X Mono (p=0.852) and Filtek Supreme XT (p=0.116) groups. Conclusion: The surface roughness of nanofil, nanoceramic and microhybrid composite resins was not effected with the use of highly concentrated carbamide peroxide home bleaching agent.
