Resumo
O objetivo deste estudo foi caracterizar a condição de higiene bucal e verificar a reprodutibilidade e a validade da autopercepção de adultos quanto à higiene bucal. Um formulário contendo perguntas sobre tipo de escova, freqüência de escovação, uso de fio dental, freqüência de visitas ao cirurgião-dentista e de autopercepção em higiene bucal foram aplicadas a 110 voluntários de 35 a 44 anos de idade. Posteriormente, foi realizado um exame clínico utilizando o Índice de Higiene Oral Simplificado (IHO-S). A aplicação do questionário e o exame clínico foram feitos em 2 ocasiões, com intervalo de uma semana. Aplicou-se a estatística kappa (κ) para o estudo da reprodutibilidade e utilizou-se o exame clínico, como critério de validação, para o estudo da validade. A reprodutibilidade da autopercepção foi ótima (κ = 0,82) e do IHO-S foi boa (κ = 0,70), mostrando que ambas as medidas são consistentes. Os valores de sensibilidade (S = 0,58) e de especificidade (E = 0,54) foram considerados satisfatórios para essa população e a acurácia indicou 55% de diagnósticos corretos. A autopercepção em higiene bucal mostrou-se reprodutível e válida como método diagnóstico no grupo investigado.

Abstract
This study aimed at characterizing the oral hygiene condition as well as at verifying the reproducibility and validity of adult self-perceived oral hygiene. A form with a few questions about the tooth brush type, brushing procedures, dental flossing, dentist visiting program and self perceived oral hygiene has been applied to 110 volunteers from 35 up to 44 years of age. Then a clinical examination using the Oral Hygiene Index - Simplified (OHI-S) was applied. The questionnaire and the clinical examination were performed in two distinct occasions, within a week interval. Kappa (κ) statistics was applied to study the reproducibility, and the clinical examination was used as a validation criterion. The reproducibility of self-perception was almost perfect (κ = 0.82), and substantial for OHI-S (κ = 0.70). This shows that both strategies are in good agreement and are therefore consistent. The sensitivity (S = 0.58) and specificity (E = 0.54) values were considered satisfactory for this group and accuracy indicated 55% of correct diagnosis. The self perceived oral hygiene has demonstrated to be reproducible and valid as a diagnostic method for the investigated group.
