Abstract

The aim of this study was to evaluate the effect of two different finishing tecniques and two different polishing procedures on the surface roughness of one nano-filled composite Filtek Supreme XT , one nano-ceramic composite CeramX and one nano-hybrid composite Grandio . 35 disk-shaped specimens 5 mm diameter and 2 mm thickness were made for each composite resin by using stainless stell mold. Specimens were randomly divided into seven finishing and polishing procedures as follow: Group 1: Mylar strip as control , Group 2: Diamond finishing burs, Group 3: Diamond finishing burs+Optidisc, Group 4: Diamond finishing burs+Hi-Luster, Group 5: Tungsten carbide burs, Group 6: Tungsten carbide burs+Optidisc, Group 7: Tungsten carbide burs+Hi-Luster. A profilometer device was used to measure the average surface roughness Ra of all the specimens. Results were statistically analysed by using Two way ANOVA and Duncan test at p

Farklı sistemlerle bitirme ve cila uygulanan üç kompozit rezinin yüzey pürüzlülüğü

Abstract

Bu çalışmanın amacı; nano-dolduruculu bir kompozit Filtek Supreme XT , bir nano-seramik kompozit CeramX ve bir nano-hibrit kompozitin Grandio yüzey pürüzlülüğü üzerine iki farklı bitirme frezi ve iki farklı cila sisteminin etkisini araştırmaktır. Her kompozit rezin için paslanmaz çelik kalıplar kullanılarak disk şeklinde 5 mm çap-2 mm kalınlık 35 örnek hazırlandı. Örnekler bitirme ve cila prosedürlerine göre rastgele gruplara ayrıldı. Grup 1: Şeffaf bant control , Grup 2: Elmas bitirme frezleri, Grup 3: Elmas bitirme frezleri +Optidisc, Grup 4: Elmas bitirme frezleri +HiLuster, Grup 5: Tungsten karbit frez, Grup 6: Tungsten karbit frez +Optidisc, Grup 7: Tungsten karbit frez +Hi-Luster. Tüm örneklerin ortalama yüzey pürüzlülük değerleri Ra profilometre ile ölçüldü. Bulguların istatistiksel değerlendirmeleri P
