摘要: This study compared the Vickers hardness of top and bottom surfaces two compomers (Compoglass F Dyract AP) polymerized for 20 40 seconds with different light curing systems. Five samples each group were prepared using Teflon molds (9x2 mm) light-cured either a conventional halogen lamp (Optilux 501) or LED (LEDemetron I) seconds. After curing, all stored in distilled water 24 hours at 37 degrees C. The measurements obtained from sample. ANOVA, Scheffe t-test used to evaluate statistical significance results. For surfaces, systems times tested showed no difference, except Optilux 501, which both (p<0.05). There was significant difference microhardness Compoglass AP cured LEDemetron I. With significantly higher than
