Abstract

Background: Bleaching has gradually became a popular procedure for people searching for aesthetic improvement. The aim of this in vitro study was to investigate the effect of bleaching with 45% car- bamide peroxide on the level of mineralization of ena- mel, using laser fluorescence.

Highlights

  • Bleaching has gradually became a popular procedure for people searching for aesthetic improvement

  • There has been used a variety of methods for the determination of the demineralization and remineralization that occur during bleaching – confocal laser microscopy, microhardness tests, microradiography, iodide permeability and surface microhardness, scanning electron microscopy, etc. [3, 6, 7, 8]

  • During the last decade bleaching has gradually become a popular procedure for people searching aesthetic improvement

Summary

Materials and methods

Sixty extracted human teeth were treated with 45% carbamid peroxide (Opalescence, Ultradent), 4 consecutive days for one hour each day. The effect of the bleaching agent on the level of mineralization of enamel was measured with DIAGNO dent pen. The statistical method we use was descriptive analysis
