摘要 目的 分析比较 3种进口光敏树脂与部分西南地区中国人牙冠颜色范围 ,研究进口树脂颜色是否适合中国人的牙冠颜色。方法 采用CIE1976L a b 颜色参数 ,应用人体牙齿颜色测量系统对DytratAP、PrismaTPH、Tetric 3种进口光敏树脂进行颜色测量 ,其颜色范围与部分西南地区中国人牙冠颜色范围进行比较。结果  3种进口树脂颜色分布范围较小 ,最大值与最小值的色差值 (CIEΔE)分别是 :13.46 8、2 7.730、11.831色差单位 ,均位于部分西南地区中国人牙冠颜色范围之内 ,但明显小于该范围。 3种进口树脂颜色分布的特点各不相同 ,颜色分布不均匀 ,缺乏高明度及底明度颜色 ,红、绿色样比重不够。结论  3种进口光敏树脂的颜色分布范围较窄 。 Objective To analyse the color ranges of 3 kinds of imported composite resin and to compare the color range of imported composite resin with that of Chinese teeth in the southwest of China. Methods The color of 3 kinds of imported composite resin was mearsured with the spectrophotonery system of human tooth color which had a fiber optic heading.The color range of imported composite resin was compared with that of Chinese teeth. Results The color distribution spaces of 3 kinds of imported compositeresin had different color ranges that were smaller than that of Chinese teeth. Being compared with Chinese teeth color, imported composite resin was short of higher and lower light color, and imported composite resin was short of greener and redder color either. Conclusions The color distribution spaces of imported composite resin are different from that of Chinese teeth in the southwest of China, and any kind of composite resin can not meet the color demand from dental clinic.
