    摘要： To eliminate a defect in conventional dental bleaching agent, that light for activating titanium oxide hardly reaches down to the titanium oxide at the teeth surface to be bleached, a dental bleaching agent set consists of two components of which the first component is attached to teeth surface and irradiation of light is followed after the second component is contacted on the teeth surface, the first component consisting of an organic solvent, containing at least one of a titanium oxide, a nitrogen doped titanium oxide, and a titanium oxinitride having photocatalytic activities, and preferably one or more of a metal oxide, a metal salt, and a metal powder, a thickener and water, the second component consisting of a compound that produces hydrogen peroxide in water, a thickener and a carrier.

    摘要： A method for bleaching teeth comprises steps of applying a solution containing nitrogen-deeped titanium oxide powder on a surface of teeth, and irradiating the applied part with light to bleach the teeth based on a photocatalytic action thus produced, and a bleaching agent for teeth suitable for carrying out the method comprises a solution containing nitrogen deeped titanium oxide powder, in which the nitrogen-deeped titanium oxide is preferably a photocatalytic substance having a Ti—O—N structure having a titanium oxide crystalline lattice containing nitrogen and exhibiting a photocatalytic action in a visible light region, the bleaching agent contains preferably 0.01 to 5% by weight of the nitrogen-deeped titanium oxide powder, the nitrogen-deeped titanium oxide powder has a specific surface area of from 10 to 500 m2/g, the solution contains water and/or an alcohol as a solvent, and the bleaching agent further contains preferably 0.5 to 20% by weight of a thickener, 1 to 20% by weight of hydrogen peroxide, and 2 to, 45% by weight of urea peroxide.
