This paper assesses the unmet orthodontic treatment need in a random sample of 10-year-old schoolchildren, using two indices: the Dental Aesthetic Index (DAI) and the Index of Orthodontic Treatment Need (IOTN). The DAI scores were adjusted by omitting the missing teeth component of the index because many children were in the mixed dentition with unerupted permanent teeth. Although both indices assessed the same number of children with malocclusions requiring orthodontic treatment, not all were ranked similarly by each index.
本文使用两种指数——牙科美学指数（DAI）和正畸治疗需求指数（IOTN），对10岁学龄儿童的随机样本进行未满足的正畸治疗需求评估。由于许多儿童处于恒牙未萌出的混合牙列阶段，因此通过省略该指数中缺失牙部分来调整DAI评分。尽管两种指数评估的需要正畸治疗的错牙合儿童数量相同，但每个指数对这些儿童的排名并非都相似。
