Effect of Curing Lights and Bleaching Agents on Physical Properties of a Hybrid Composite Resin
Lima DANL et al. - For DTS, there were no statistical differences among the bleaching agents and the control group; however, the halogen group presented statistically lower DTS than the LED group. For the MH test, the carbamide peroxide group presented statistically lower MH means than the control groups, and there were no statistical differences among the light-curing units. Sixteen percent carbamide peroxide reduced the MH of the hybrid composite tested. The second generation LED presented a performance similar to or better than the halogen lamp for hardness and DTS, respectively. [more...]
