Tooth bleaching effect on color alteration and translucency is similar in enamel and dentin
This study evaluated the effects of tooth bleaching on alterations of translucency parameter (TP), and color of dentin and enamel. The color of specimens containing only enamel or dentin were measured over white and black backgrounds using a spectrophotometer (CieL*a*b), allowing the calculate the T...

| Sumario: | This study evaluated the effects of tooth bleaching on alterations of translucency parameter (TP), and color of dentin and enamel. The color of specimens containing only enamel or dentin were measured over white and black backgrounds using a spectrophotometer (CieL*a*b), allowing the calculate the TP by difference between the color measured over each background. The measurement was repeated after tooth bleaching with 35% hydrogen peroxide and ∆E and ∆TP were calculated. Data were analyzed by Ttest (α = 0.05). No difference was observed between dentin and enamel regarding alterations on TP and color. |
