摘要
目的：观察不同的正畸治疗指数评价正畸治疗需要的一致性。方法：随机选取220副正畸记存模型，采用常用的4种指数评估这些模型是否需要正畸治疗，并对结果的一致性进行分析。结果：不同的指数鉴定出有不同数量的模型需要正畸治疗（31．6％-85．9％），各指数间的判断结果有显著但弱的相关性，各指数间的一致性较低。结论：采用不同的指数会有不完全相同的结果。
Objectives： To determine the agreement among the occlusal indices used to determine the orthodontic treatment need. Methods： Study models （220） were screened for orthodontic treatment need using a number of professionally derived indices. Index of Orthodontic Treatment Need （IOTN）, Aesthetic Component （AC） and Dental Health Component （DHC）. Index of Complexity, Outcome and Need （ICON） and the Dental Aesthetic Index （DAI）. Agreement among the four indices was drived by calculating Spearman＇s rank correlation coefficients and Kappa values. Results： Different prevalence of orthodontic treatment need was observed depending on occlusal indices used （ ranged from 31.6% to 85.9% ）. However, there were generally weak but significant correlations between the different occlusal indices （P〈0.01 ）. The agreement among the indices was poor. Conclusion： Different occlusal indices （AC, DHC, ICON and DAI） prescribe different orthodontic treatment need.
