Abstract
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.
