    • It is a major object of the present invention to reduce the time required for bleaching discolored teeth by using a photocatalyst to thereby provide a bleaching material which is simple to use. The present invention relates to a bleaching material for bleaching teeth by applying a solution or paste comprising BiVO4 photocatalyst and a compound which generates hydrogen peroxide in an aqueous solution onto the surface of discolored teeth, and irradiating the surface with light, thereby bleaching the teeth by resultant photocatalytic action. The present invention provides a bleaching material for discolored teeth comprising as active ingredients BiVO4 photocatalyst and a compound which generates hydrogen peroxide in an aqueous solution; and a method of bleaching discolored teeth using the above material.
    • 本发明的主要目的是通过使用光催化剂来减少漂白变色牙齿所需的时间,从而提供易于使用的漂白材料。 本发明涉及通过将含有BiVO 4光催化剂的溶液或糊剂和在水溶液中产生过氧化氢的化合物施加到变色牙齿的表面上来漂白牙齿的漂白材料,并且照射表面 用光,从而通过产生的光催化作用漂白牙齿。 本发明提供一种用于变色牙齿的漂白材料,其包含作为活性成分的BiVO 4光催化剂和在水溶液中产生过氧化氢的化合物; 以及使用上述材料漂白变牙的方法。
