Abstract

Recently, the clinical uses of flowable composite resins have increased because of fast. convenient and excellent accessibility, but little has been reported about physical properties of flowable resins.
The purpose of this study was to measure and compare the physical properties(compressive
strength. relative flowability, relative radiopacity) of 4 comtemporary flowable composite resins(Filtek flow, Tetric Flow. Revolution Palfique Estelite LV high flow) .
The results were as follows;
1. There were no significant differences between 4 flowable composite resins in compressive strength, but all were lower than that of traditional hybrid composite resin(p<0.001).
2. The relative flowability were increased in order of Palfique Estelite L-V high flow, Revolution. Filtek flow, Tetric Flow and sealant(p<0.001). but there were no sitgnificant differences between Filtek flow and Tetric Flow
3. There were significant differences between flowable composite resins in relative radiopacity and they showed similar or higher radiopacity than dentin(p<0.001), especially Tetric Flow and Filtek Flow showed higher radiopacity than enamel(p<0.001).
This results suggested that the stress of application area have to be considered since flowable
composite resins have lower compressive strength than hybrid composite, and the differences of flowability between these flowable composite resins can be considered when they are selected. All tested flowable composite resins showed optimal radiopacity to ISO´s recommend.
