Abstract:
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).
