COMPARISON OF THE MICROHARDNESS OF BULK FILL COMPOSITES

The aim of this study is to compare the microhardness five different bulk fill composites (SDR, TEC, XTF, SF, FBF). A total 25 cylindrical molds were prepared. Composite resin was placed in each mold sequence, at one time, by condensing it thoroughly. Then, polymerization achieved with LED light device which applied for 20 seconds. Microhardness measurements samples made classical Vicker's test. data our evaluated using Kruskal Wallis H test SPSS 20.0 package program. When measured surface values compared between groups; SDR and FBF groups found be significantly lower than XTF KSF (p<0.05). sub-surface value group higher group, both upper groups, composite best microhardness.
