摘　　要：目的:评价口腔正畸治疗需要指数(IOTN)的操作者间及操作者内的一致性。方法:由三名经过培训的口腔正畸医生使用口腔正畸治疗需要指数(IOTN)分三天分别对80个病人进行评估。每个病人先根据牙齿健康组件评估为1～5级,,再进一步根据美观组件进行1～10的评估,由助手记录结果。每位医生再从自己已检查过的患者中随机抽出10名,三天后进行再一次评估。结果:口腔正畸治疗需要指数(IOTN)的牙齿健康组件(DHC)操作者间的两两Kappa值分别为0.54,0.62,0.61,牙齿美观组件(AC)操作者间的两两Kappa值分别为0.64,0.72,0.51。三名医生的牙齿健康组件(DHC)操作者内Kappa值分别为0.74,0.69,0.71,三名医生的牙齿美观组件(AC)操作者内Kappa值分别为0.67,0.75,0.79。结论:口腔正畸治疗需要指数操作者间及操作者内具有较好的一致性,可应用该评价工具对我国人群的口腔正畸治疗需求进行评估。Objective：The aim of this study was to establish whether the Index of Orthodontic Treatment Need （IOTN） is reliable by calculating the Kappa value of intra-examiner agreement and inter-examiner agreement. Method： To test the inter-examiner agreement, 80 patients were diagnosised respectively by three examiners according to the dental health component （DHC） of IOTN and the aesthetic component （AC） of IOTN, and the assistants recorded the result. Intra- examiner reliability was measured by re-scoring a random sample of 10 from 80 patients three days apart. Result： The Kappa value of the inter-examine agreement （between two examiners）, of DHC is respectively 0.54, 0.62, 0.61, The Kappa value of the inter-examine agreement （between two examiners）, of AC is respectively 0.64, 0.72,0.51. The Kappa value of the intra-examine agreement of DHC is respectively 0.74, 0.69, 0.71. The Kappa value of the intra-examine agreement of AC is respectively 0.67,0.75,0.79. Conclusion： IOTN has a good intra-examiner agreement and inter-examiner agreement. It can be used in clinic to evaluate the need of orthodontic treatment among the Chinese population.
