METHOD FOR BLEACHING DISCOLORED TOOTH BY TITANIUM DIOXIDE PHOTOCATALYST
摘要
<p>The present invention relates to a method for bleaching a discolored tooth, comprising the steps of applying a solution/paste of titanium dioxide powder and hydrogen peroxide solution onto the surface of discolored teeth, and bleaching the tooth based on the photocatalytic action that is produced by irradiating this area with light; and to a bleaching agent for applying onto the surface of discolored tooth to bleach the discolored tooth based on the photocatalytic action that is produced by irradiating this area with light, the bleaching agent comprising as active ingredients a combination of hydrogen peroxide solution and titanium dioxide producing photocatalytic action when irradiated with light.</p>
