ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of the cold-light bleaching technique on crystals and microstructure of the dental enamel.</p><p><b>METHODS</b>The human premolars extracted for orthodontic reasons were treated by a standard cold-light bleaching procedure. After the treatment, all samples were detected by high resolution micro-area X-ray diffractometer, Fourier transform infrared spectroscope and scanning electron microscope.</p><p><b>RESULTS</b>After the permanent teeth were treated with cold-light bleaching technique, the enamels' crystal dimension, crystallinity decreased and irregular surfaces and shallow disk pits appeared.</p><p><b>CONCLUSION</b>The cold-light bleaching technique could lead to the changes of crystals and microstructure in the surface layer of dental enamel.</p>
