A Comparative Evaluation of Chemically Activated, Lightactivated and Laser-activated Tooth Bleaching Systems on Whitening Efficacy and Effect on Enamel Surface Texture: An in vitro Study

Abstract

Background: Tooth bleaching systems can be classified as chemically activated, light-activated and laser-activated depending on activation mechanism. There is no unanimity of opinion with respect to the whitening efficacy and effect on enamel surface texture of these three types of systems. So, the present study was carried out to comparatively evaluate their whitening efficacy and effect on enamel surface texture.
