Establishment of artificial discoloring tooth model for evaluation of tooth bleaching

本课题的目的是确定各种因素对牙齿漂白的影响，建立人工牛变色牙模型，评价漂白材料和方法。氧化钛光催化剂和双氧水对牙齿漂白效果的影响；波长、光源强度、照射时间。该人工变色牛牙模型可为牙齿漂白材料和方法的评价提供依据。

The purposes of this project was to determine the effect of various factors on tooth bleaching and to established the artificial bovine discolored tooth model for evaluating bleaching materials and methods. The tooth bleaching using titanium oxide photocatalyst and hydrogen peroxide was affected the conditions of photo irradiation; wave length, intensity of light source and irradiation time. The artificial discolored bovine tooth model was useful for evaluation of tooth bleaching materials and methods.
