ABSTRACT
OBJECTIVE: This study aimed to assess the consistency of data regarding the provision of fluoridation in Brazilian municipalities with water supply systems. METHODS: Official data from the National Basic Sanitation Survey and the National Information System on Sanitation for 2017 were compared. RESULTS: Out of 5,570 municipalities in Brazil, 4,546 (81.6%) had water supply systems. The agreement between data sources was 84%, with a Kappa of 0.668, indicating substantial agreement. However, the estimates of fluoridation provision exhibited an average discrepancy of 8.1 percentage points, ranging from 1.2 points in the Central-West region to 21.4 points in the Northeast region. CONCLUSION: To address these inconsistencies, it is essential to enhance information sources, ensuring more reliable data for health, sanitation authorities, and society at large.

RESUMO Objetivo: Avaliar a consistência dos dados sobre a provisão de fluoretação em municípios brasileiros com sistemas de abastecimento de água. Métodos: Foram comparados os dados da Pesquisa Nacional de Saneamento Básico e do Sistema Nacional de Informações sobre Saneamento referentes a 2017. Resultados: De 5.570 municípios no Brasil, 4.546 (81,6%) possuíam sistemas de água. A concordância entre as fontes foi de 84%, com Kappa de 0,668, indicando substancial concordância. Entretanto, as estimativas de provisão divergiram em média 8,1 pontos percentuais, variando de 1,2 ponto na região Centro-Oeste a 21,4 pontos na região Nordeste. Conclusão: Para superar essa inconsistência, é fundamental aprimorar as fontes de informação, garantindo dados mais confiáveis para as autoridades de saúde, saneamento e para a sociedade em geral.
