摘　　要：目的：观察高可见光催化材料氮掺杂纳米二氧化钛（纳米 N-TiO2）对光固化灯光导棒的消毒效果。方法：选取某医院6个口腔诊室的50个光导棒，采用ATP生物荧光法，检测光导棒表面喷涂纳米 N-TiO2前后的细菌黏附状况。结果：暴露于空气中的光导棒表面相对光单位值（RLU）为51～649；喷涂纳米 N-TiO2后，其RLU值为0～6（P＜0.01）。结论：纳米 N-TiO2对光固化灯的光导棒具有很强的消毒作用。Objective：To observe the disinfection efficiency of N-doped nano-TiO2 on the curing light-guide rods.Methods：50 light-guide rods from 6 dental clinics were included,the bacteria adhesion on the light-guide rods before and after disinfection with N-doped nano-TiO2 was investigated using ATP bioluminescence method.Results：The RLU value of light-guide rods exposed to the air was 51 -649 before the use of N-doped nano-TiO2 disinfection,after spraying N-doped nano-TiO2 ,the RLU value of light-guide rods was 0 -6（P〈0.01 ）.Conclusion：N-doped nano-TiO2 has significant sterilization effect on the curing light-guide rods.
