Özet
The aim of this study is to examine the effect of different finishing and polishing systems on the surface roughness, microhardness and microleakage of a nano-hybrid composite.The effect of four different finishing and polishing systems (Mylar-strip, Diamond finishing bur, Sof-lex disc, PoGo) were evaluated on a nanohybrid composite (Ceram-X mono, Denstply).The surface roughness was measured by profilometer, microhardness was measured by Vicker's microhardness tester.For microleakage evaluation, class V cavities (3x4x2 mm) were prepared at cemento-enamel junction of 60 third molars.Teeth were thermocycled 500 times (5-55oC) and immersed in 0.5% basic-fuchsin for 24-hours and evaluated.The two-way ANOVA and Posthoc tests were used for surface roughness, One-way-variance-analysis and Posthoc tests were used for microhardness and microleakage was analyzed by Kruskal-Wallis and Mann-Whitney-U tests.Measured surface roughness scores listed according to the techniques as; PoGo<Mylar-strip=Sof-lex<Diamond bur (p=0.000),microhardness scores as; Mylar-strip=diamond bur<Sof-Lex<PoGo (p=0.010),microleakage scores as; PoGo<diamond bur=Mylar-strip
