Resumen

Objectives: To evaluate the effect of Opalescence™ PF home bleaching gel on the color stability ofAmelogen™ Plus microhybrid composite resin. Material and method: Thirty disks were fabricated fortesting using three different shades (A1, A2 and A3.5) of Amelogen™ Plus composite. Standardized L*a*b*parameters were determined and the specimens were subjected to 15% carbamide peroxide. The L*a*b*parameters were measured again and the color change (ΔE) in the composite disks were calculated. Thedata were analyzed using the One-way ANOVA and Tukey tests. (α = 0.05) Results: In all specimens themean of ΔE was more than 3.3. There was a signifi cant difference between shade A3.5 and A2 and withshade A1, as A1 showed the lowest values of color change with bleached composites being lightened incomparison with the unbleached specimens. The greatest change occurred in the red-green (a*) parameter.Conclusion: 15% carbamide peroxide bleaching gel (Opalescence® PF) caused a clinically detectable colorchange with each of three different shades (A1, A2 and A3.5) of Amelogen™ Plus (ΔE> 3.3) tested. Thegreatest color change occurred with the A3.5 shade and the least change was associated with the A1 shade.
