Objectives : To evaluate the prevalence of dental erosion in schoolchildren 05-15 years of the medium-sized city in northeastern Brazil and compare the reproducibility and performance of two indices of erosion , BEWE O'Sullivan and Methods : Children (n=661) of 5- 15-year-old were examined at publics schools in João Pessoa, Paraíba. The sampling procedures were based in population cluster and a randomly selection of schools and systematic selection of individuals. The indexes for the detection of dental erosion were: O'Sullivan (2000) and BEWE (2008). Primary and permanent teeth were examined under indirect natural light. All subjects did supervised toothbrusing and the dental surfaces were examined after drying procedures. For comparative purposes, the index were dichotomized and divided into four thresholds according to severity. The teeth were examined by two calibrated examiners (Kappa intra–examiner >0.66 and inter-examiner of 0.89). The statistical inferences were bivariate, binomial test, t test and Fisher's exact test when appropriate with a value of 5 % probability. Results: The prevalence of dental erosion was 26.93 % with same distribution for males and females (50% for both). Older schoolchildren ( 10-15 years) had the highest prevalence ( 51.12 % ) . The sociodemographic characteristics of gender, age, race and biofilm presence was statistically associated ( p < 0.05 ) with the dental erosion . Regarding behavioral factors was no significant association ( p > 0.05 ) between the assessed dietary habits (consumption frequency of acids foods, industrialized juices, soft drinks or use of fluoride) and the presence of dental erosion . Most lesions are restricted to the enamel ( scores 1 and 2 ) . The palatal surface in incisors was more affected with more than half of the surface affected, while the molars, the occlusal surfaces had the highest prevalence, with less than half of the surface affected. The performance indices shown concordance of 95.3% (p <0.05). A comparison of severity thresholds showed substantial Kappa values from (0.779) and excellent (0.94). Conclusions: The results indicate a median prevalence of dental erosion and being observed with the same distribution about males and females. It can be concluded that this population remains under the effect of erosion factors as the prevalence was higher than a previous study in the same location. The BEWE is an index with good agreement as to the clinical condition of erosion and can be applicable in population-based studies .
