EFFECT OF WHITENING MOUTHRINSES ON SURFACE ROUGHNESS OF COMPOSITE RESIN

Abstract

Objective: The aim of this in vitro study was to evaluate the effect of whitening mount rinses on superficial roughness a nanofilled resin composite. Methods: Sixty-three nanofilled composite resin specimens (8 mm x 2 mm) were prepared and randomly divided into seven groups, according to the mouthrinse solutions (n = 9): Oral-B 3D White, Crest 3D White, Colgate Optik Beyaz, Scope White, Signal White Now and Listerine Whitening Vibrant. The control group used in the study was distilled water. The initial surface roughness measurements (Ra) were measured with a profilometer and then the each sample was immersed in 2 mL of the mouthrinses for 14 days period. After immersion period, roughness readings were repeated and the data were analyzed with ANOVA and Scheffe test (p<.05). Results: The profilometric assessment showed that exposure to mouthrinse resulted in a slightly increase in roughness values in all groups. But, the differences between mouthrinses groups and the control group were not statistically significant (p > 0.05). Conclusion: We conclude that the influence of the whitening mouthrinses on the surface roughness of dental resin composite was negligible

BEYAZLATICI AĞIZ GARGARALARININ KOMPOZİT REZİNİN YÜZEY PÜRÜZLÜLÜĞÜ ÜZERİNE ETKİLERİNİN İNCELENMESİ

Abstract

Amaç: Bu in-vitro çalışmanın amacı beyazlatıcı ağız gargaralarının bir nanofil kompozit rezinin yüzey pürüzlülüğü üzerine olan etkilerini incelemektir.

Gereç ve Yöntem: Altmış üç nanofil kompozit rezin örneği (8 mm x 2 mm) hazırlandı ve kullanılan ağız gargarasına göre yedi gruba ayrıldı (n = 9); Oral-B 3D White, Crest 3D White, Colgate Optik Beyaz, Scope White, Signal White Now ve Listerine Whitening Vibrant. Kontrol grubu olarak ise distile su kullanıldı. Başlangıç yüzey pürüzlülüğü değerleri (Ra) bir profilometre yardımıyla ölçülüp kaydedildikten sonra her örnek 2 mL solüsyon içerisine konuldu ve 14 gün süresince beklenildi. Bekletilme süresinin sonunda yüzey pürüzlülüğü ölçümleri tekrarlandı ve elde edilen değerlerin istatistiksel analizleri ANOVA ve Scheffe testleri ile gerçekleştirildi (p<.05).

Bulgular: Profilometerik değerlendirmeler, ağız gargaralarına maruz kalan tüm örneklerin yüzey pürüzlülüğünde küçük bir artış olduğunu göstermiştir. Ancak bu artışın ağız gargaraları ve kontrol grubu arasında istatistiksel olarak önemsiz olduğu belirlen- miştir (p > 0.05).

Sonuç: Hidrojen peroksit içeren beyazlatıcı ağız gargaralarının nanofil kompozit rezinin yüzey pürüzlü- lüğü üzerine olan etkilerinin göz ardı edilebilecek seviyede olduğu bu çalışmada gösterilmiştir.
