| Abstract: | Objective: This study evaluated the micro-hardness of light-cured composite resin of different light sources, materials ,exposure duration time and depth. Methods:Micro-hardness of 4 representative composite resin were evaluated for light source, duration time,depth and analyzed with ANOVA (P<0.01). Results:The micro-hardness of composite resin changed with different light source, materials, duration time, and depth. Conclusion:There was a significance difference among micro-hardness of light-cured composite resins. High intensity light, extension duration time,and thin layer may increase the micro-hardness of light-cured composite resin. |
| Keywords: | composite resin micro-hardness curing light intensity duration time depth |
