| dc.description.abstract | Objectives: This study aims to evaluate the effect of a 6% hydrogen peroxide (H2O2) solution, activated with UV-light, in colour, wear, microhardness and roughness of enamel surface. Methods: Five teeth were cut, polished and exposed to black tea solution to confer them a dark color. The specimens were tested before and after bleaching using a spectrophotometer colour equipment, a nanotribometer, a micro durometer and a SEM. Results: On comparing with untreated, the treated enamel surface showed an improvement of colour but a reduction of microhardness and an increase of roughness and wear. Conclusions: A 6% hydrogen peroxide solution, activated with UV-light, has capacity to induce alterations in enamel surface making it less hard and more susceptible to wear. | pt_PT |
