上海地区初中学生正畸治疗需要及治疗难度的调查研究

Investigation of orthodontic treatment need and treatment difficulty of junior high school students in Shanghai

目的：采用正畸治疗难度、结果和需要指数（index of orthodontic treatment complexity ，outcome and need ，ICON ）评价上海地区初中学生正畸治疗难度及客观治疗需要。方法：抽取上海中心城区12～15岁初中生365名作为研究对象。采用ICON评价研究对象正中咬合时正面相及牙颌模型，分析正畸治疗难度与正畸治疗需要。结果：正畸治疗需要方面，不需要正畸治疗占62．19％、需要正畸治疗占37．81％。正畸治疗难度方面，根据ICON的评分结果，在365例被调查者中，正畸治疗难度为“容易”占43．56％、“较容易”占31．51％、“中等难度”占12．88％、“困难”占5．75％、“非常困难”占6．30％。男女性正畸治疗难度、正畸治疗需要差异均无统计学意义。结论：在被调查初中生中，需要接受正畸治疗者较多，多数正畸治疗难度不大，治疗困难与非常困难者较少。

Objective：To assess the orthodontic treatment difficulty and objective need of junior high school students in Shanghai by using the index of complexity ,outcome and need （ICON） .Methods：365 junior high school students in central urban area of Shanghai were selected by convenience sampling method .The ICON was used to evaluate the front view and the dental cast of the study objects during central occlusion ,and the orthodontic treatment complexity and need were analyzed . Results：In treatment need ,62 .19% of the students did not need orthodontic treatment ,and 37 .81% of the students needed orthodontic treatment .According to ICON scores ,in orthodontic treatment complexity ,43 .56% of the students were easy , 31 .5% were mild ,12 .88% were moderately difficult ,5 .75% were difficult ,and 6 .30% were very difficult .There was no significant difference in orthodontic difficulty and orthodontic need between boys and girls .Conclusions：In the investigated junior high school students ,more need orthodontic treatment .Most of the treatments were not difficult ,and a small part of the treatments were difficult and very difficult .
