To evaluate the prevalence of malocclusion and orthodontic treatment need among Spanish adolescents and compare with other populations.
The study sample comprised 744 schoolchildren from urban and rural populations in Granada province (Southern Spain), aged from 14-20 years, who had received no orthodontic treatment. The measurement instrument was the Dental Aesthetic Index (DAI).
The mean DAI score of the whole series was 25.6 (SD, 7.94). The distribution of the four DAI grades was: DAI 1, no anomaly or malocclusion, 58.6%; DAI 2, definite malocclusion, 20.3%; DAI 3, severe malocclusion, 11.2%; DAI 4, very severe or disabling malocclusion, 9.9%. There were no statistically significant differences in DAI score between genders or those in rural vs. urban residence, but a significant difference was found between social classes, with subjects of low social class presenting the worst scores (p<0.05).
The distribution of DAI scores among Spanish adolescents is similar to that reported in other populations.
评估西班牙青少年错牙合畸形的患病率及正畸治疗需求，并与其他人群进行比较。
研究样本包括来自西班牙南部格拉纳达省城乡的744名学龄儿童，年龄在14至20岁之间，均未接受过正畸治疗。测量工具为牙齿美学指数（DAI）。
整个样本系列的平均DAI评分为25.6（标准差，7.94）。四个DAI等级的分布情况为：DAI 1，无异常或错牙合畸形，58.6%；DAI 2，明确的错牙合畸形，20.3%；DAI 3，严重错牙合畸形，11.2%；DAI 4，非常严重或致残性错牙合畸形，9.9%。性别之间或城乡居住者之间的DAI评分无统计学显著差异，但社会阶层之间存在显著差异，社会阶层较低的受试者得分最差（p<0.05）。
西班牙青少年中DAI评分的分布与其他人群报告的情况相似。
