Abstract
Objectives: This study was examined the surface microhardness of three kind of bulk fill composites Surefil SDR flow, Tetric, EvoCeram, X-tra base) Materials and Methods: Ten specimens of 2mm, 4mm thickness and 4mm diameter of each bulk fill composite were polymerized using a halogen light and a blue light-emitted diode. Microhardness evaluation was performed at the top and bottom surfaces for each specimen using a Vickers microhardness tester. Results: All of the materials were cured with the light sources and the values obtained for the bottom surfaces were found to be lower than the values of top surfaces. Highest microhardness level (40.02±4.06) among all composite materials belonged to Xtra base composite group, whereas lowest microhardness level (5.80±0.83) was of SDR composite specimens. Conclusions: Hardness ratio range was between 0.19±0.3 and 0.72±0.06. Hardness ratio value was found to be lower than 0.80 for all composite groups.
