Abstract:

The aim of this study was evaluate the ability of the indexes DAI and IOTN in predicting the need of orthodontic treatment based in one property: reproducibility. The index DAI was developed in USA (1989) and is able to identify 10 oclusal alterations that result, mathematically, in scores, with weights based in its relative importance according with the judgment of laypeople. The IOTN was developed in England (1989) and incorporates an aesthetic component AC and a component of dental health DHC. The AC component consist of a scale illustrated with 10 photos which had been divided in bands of degrees in accordance with a hierarchic scale and is able to classify the patients in degrees of treatment need. The instruments of collection of the data were: plastic rule of component DHC and an aesthetic visual scale of component AC praised for the IOTN and one periodontal OMS probe praised for DAI. The sample was composite by 60 patients. The results indicated that the both indexes was highly reproducible in accordance with Pearson and Spearman coefficients, which were strengthened by tests “t” of Student and Wilcoxon, respectively. The correlation results between the examiners had varied between r=0,85 and r=1,00.
