Abstract
In this article effect of light exposure time on hardness of visible light cured composites with different microfiller ratios were investigated. For this purpose specimens with heights 1, 2, 3 mm and 6 mm in diameter were prepared. During the preparation of the specimens, half of the specimens were cured with visible light for 40 seconds and the other half for 60 seconds. Surface hardness values were measured from the top and bottom of the specimens immediately after the light source was removed with Barcol Hardness tester. Surface hardness were also measured 24 hours and 7 days later. Results were statistically evaluated.
