O objetivo deste estudo foi avaliar a capacidade dos indices DAI e IOTN em predizer necessidade de tratamento ortodôntico baseado em uma propriedade: reprodutibilidade. O índice DAI foi desenvolvido nos Estados Unidos (1989) e identifica 10 alterações oclusais que resultam, matematicamente, em escores, com pesos específicos baseados em um determinado grau de importância de acordo com o julgamento de pessoas leigas. O IOTN foi desenvolvido na Inglaterra ( 1989) e possui um componente estético -AC - e um componente dentário – DHC. O componente AC consiste em uma escala ilustrada com 10 fotos as quais representam um escala hierarquica de necessidade de tratamento ortodôntico. Os instrumentos para coleta de dados foram: uma régua plástica do componente DHC e a escala visual do componente AC para o índice IOTN; sonda periodontal da OMS utilizada no índice DAI . A amostra foi composta por 60 pacientes. Os resultados indicam que ambos os indices foram altamente reprodutíveis de acordo com os coeficientes de Pearson e Spearman. Para esses coeficientes foram utilizados, respectivamente, teste “t” de Student e Wilcoxon. O resultado de correlação entre os examinadores various entre r = 0,85 e r = 1,00.
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.
