TOOTH BLEACHING COMPOSITIONS AND METHODS FOR BLEACHING DISCOLORED TOOTH

摘要

The bleaching compositions of discolored teeth comprisetitanium dioxide initiating photocatalyst action with light irradiation,chemical compounds generating hydrogen peroxide in an aqueoussolution and thickening agents. Further the bleaching methods ofdiscolored teeth comprising applying the bleaching composition ontothe surface area of the teeth and then initiating photocatalyst actionby irradiating the applied surfaces area with light. Therefore, thepresent invention shows remarkable bleaching results due to easyapplication of the compositions onto discolored teeth and keeping theoriginal activity of the photocatalyst without its deterioration.
