BLEACHING MATERIAL FOR TOOTH

摘要

PROBLEM TO BE SOLVED: To provide a bleaching material which has good long shelf stability and is easily applied to a discolored tooth in practical use and further imparts enough bleaching effect without decreasing initial photocatalytic activity and has good safety for a human body. SOLUTION: The bleaching material comprises two liquids, an aqueous mixed liquid of titanium dioxide which generates photocatalytic action by an inorganic thickener and with light irradiation, and a mixed liquid of a compound generating hydrogen peroxide in a water solution with a phosphoric aid and a condensed phosphoric salt.
