Effect of in-office bleaching with 35% hydrogen peroxide with and without addition of calcium on the enamel surface.

This study aimed to evaluate effectiveness and effects of bleaching with 35% hydrogen peroxide with and without calcium on color, micromorphology, and the replacement of calcium and phosphate on the enamel surface. Thirty bovine enamel blocks (5.0 × 5.

Evaluation of the effect of different methods of microabrasion and polishing on surface roughness of dental enamel.

Description Of The Technique: The microabrasion technique of enamel consists of selectively abrading the discolored areas or causing superficial structural changes in a selective way.

Objective: In microabrasion technique, abrasive products associated with acids are used, and the evaluation of enamel roughness after this treatment, as well as surface polishing, is necessary. This in-vitro study evaluated the enamel roughness after microabrasion, followed by different polishing techniques.
