An Environmental Scanning Electron Microscopy Evaluation on Comparison of Three Different Bleaching Agents using the Laser Activated in-Office Bleaching at Different Wavelengths.

Background: Shade of the teeth is of specific significance to the patient because of social and psychological concern and hence plays vital role as primary care. Bleaching is a noninvasive, relatively inexpensive, conservative, and low-maintenance method to change a smile dramatically.

Aim: To study the effect of application of three bleaching agents at different wavelengths of laser on the enamel surface of teeth using an environmental scanning electron microscopy (ESEM).
