The Effects of Different Polishing Systems on Surface Roughness of Nano-Composite

Abstract

The aim of this study was to evaluate the effects of different polishing systems on surface roughness of nano-composites. For this purpose, two nano-composites Grandio, VOCO ve Filtek SupremeUltra Enamel, 3M/ESPE and three polishing systems were used. 40 samples were prepared for each of the composites N=80 . All the samples were prepared in a plexiglass molds againist a polyester strip. The samples were divided into 4 subgroups for different polishing systems n=10 . Except the control groups, all the other remaining groups were finished with cabid bur and following polishing systems were performed: SoftLex XT Group SL , PoGo Group PG , Astropol Group AS . Profilometer was used for assessing the surface roughness of composite samples. Parametric two-way analyses of variance were used for statistical evaluation of average roughness data of samples Ra and Tukey HSD tests were used for multiple comparison of averages p=0,05 Two of the resin composite groups were compared, the lowest Ra value was obtained at Filtek SupremeUltra Enamel group, the highest Ra value was obtained in Grandio group, and this difference was statistically significant p

Farklı cila sistemlerinin nano-dolduruculu kompozitlerin yüzey pürüzlülüğü üzerine etkisi

Abstract

Bu çalışmanın amacı farklı cila sistemleri kullanarak iki farklı doldurucu türüne sahip kompozit rezin materyalin yüzey pürüzlülük özelliklerini incelemektir. Bu amaçla iki farklı nanokompozit Grandio, VOCO ve Filtek SupremeUltra Enamel, 3M/ESPE ve üç farklı cila sistemi kullanılmıştır. Her bir kompozit materyalden 40’ar adet örnek hazırlanmıştır N=80 . Tüm örnekler pleksicam kalıplarda hazırlanmış ve polyester bant kullanılarak polimerize edilmiştir. Örnekler farklı cila işlemleri uygulanmak üzere 4 alt gruba ayrılmıştır n=10 . Kontrol grubu Grup K haricindeki diğer gruplara, önce karpit frez ile bitirme işlemi uygulanmış, sonrasında şu cila sistemleri uygulanmıştır: Soft-Lex XT Grup SL , PoGo Grup PG , Astropol Grup AS .Örnekler; yüzey pürüzlülüğündeki değişimlerin değerlendirilebilmesi için optik profilometre kullanılarak incelenmiştir. Örneklerin ortalama yüzey pürüzlülüğü Ra verilerinin istatistiksel olarak değerlendirilmesinde çift yönlü varyans analizi, ortalamaların çoklu karşılaştırılmasında ise Tukey HSD testi kullanılmıştır p=0,05 . İki kompozit rezin grubu değerlendirildiğinde en düşük Ra değeri Filtek Supreme XT Enamel grubununda izlenmektedir. Grandio grubunun Ra değeri daha yüksektir ve bu farklılık istatistiksel olarak anlamlıdır p
