Three aesthetic indices namely aesthetic component of index of orthodontic treatment needs (IOTN -AC), dental aesthetic index (DAI) and dental aesthetics screening index (DESI) were compared in orthodontic treatment. 242 participants (160 female and 82 male) who were interested in orthodontic treatment participated. The individuals' ages ranged from 16-25 years. Three aesthetic indices namely IOTN -AC, DAI and DESI were evaluated for each participant. The overall accuracy of DAI, AC-IOTN and DESI in assessment of dental aesthetics in orthodontic treatment was 62%, 68% and 64% respectively. The Negative predictive value (NPV) was higher than Positive predictive value (PPV) for all indices. The sensitivity was greater than specificity for all indices. It was observed that values of sensitivity, specificity, PPV and NPV were high for AC-IOTN. The findings were significant statistically (p<0.05).
在正畸治疗中，对正畸治疗需求指数的美学成分（IOTN-AC）、牙齿美学指数（DAI）和牙齿美学筛查指数（DESI）这三个美学指标进行了比较。242名对正畸治疗感兴趣的参与者（160名女性和82名男性）参与其中。参与者的年龄在16至25岁之间。对每位参与者评估了IOTN-AC、DAI和DESI这三个美学指标。DAI、AC-IOTN和DESI在正畸治疗中评估牙齿美学的总体准确率分别为62%、68%和64%。所有指标的阴性预测值（NPV）高于阳性预测值（PPV）。所有指标的敏感性均大于特异性。观察到AC-IOTN的敏感性、特异性、PPV和NPV值较高。研究结果具有统计学意义（p<0.05）。
