Microabrasion effect on enamel susceptibility to penetration of hydrogen peroxide: an experimental and computational study.

To evaluate in vitro transenamel/transdentinal of penetration of HO after microabrasive. Computational models were performed to verify peroxide penetration and evaluate if geometric modifications could affect in vitro results. Enamel/dentin blocks from bovine incisors were prepared and randomly divided into groups (n = 15) according with abrasive (35% phosphoric acid and pumice or 6.
