"Impact of Bleaching Gels on Dental Enamel Microhardness and 3D Surface Roughness"@en . "At this time, the popularity of dental bleaching has increased in esthetic dentistry. Tooth bleaching using different oxidizing agents as hydrogen peroxide or carbamide peroxide is one of the most spread procedures. The effect of bleaching treatment on dental enamel has long been a concern of many dentists, because bleaching agents react with enamel and cause chemical, structural and mechanical changes on the enamel surfaces. One of the most common methods of evaluation of changes in surface topography5,6 is electron microscopy, stylus profilometery or atomic force microscopy7. The aim of this work is to investigate the effect of two different tooth bleaching gels containing 22% carbamide peroxide and 38% hydrogen peroxide on surface microhardness and properties of dental enamel by the 3D surface topography."@en .
