Light-activated bleaching: effects on surface mineral change on enamel.
AIM This study evaluated the in vitro effect of 35% hydrogen peroxide (HP) on surface enamel change when activated with different light curing units (LCUs). MATERIALS AND METHODS Enamel blocks (4 × 4 × 2 mm) were obtained from bovine incisors. The initial microhardness of the enamel was determined for each specimen. After this enamel blocks were randomly divided into four groups (n = 10) and ...

متن کاملDental bleaching with ozone: effects on color and enamel microhardness.
The aim of this in vitro study was to evaluate the effects of dental bleaching with ozone (O3) on color change and enamel microhardness. Enamel blocks (3 x 3 x 3mm) were randomly distributed for treatments (n=10). Color change (ΔE) and Knoop microhardness of the enamel blocks were evaluated before and after the following treatments: C - deionized water (control); HP - 37.5% hydrogen peroxide (P...
