Resumo
Objetivo: A hipomineralização molar-incisivo (HMI) é um defeito qualitativo do esmalte de etiologia ainda não esclarecida, que afeta um ou mais molares permanentes e, por vezes, incisivos. Representa um desafio clínico, e sua real prevalência permanece incerta devido à recente expansão das pesquisas. Este estudo teve como objetivo estimar a prevalência de HMI e suas características associadas por meio de uma revisão integrativa. Métodos: Foi realizada uma busca na literatura nas bases de dados PubMed, SciELO e LILACS até janeiro de 2024, incluindo 27.781 participantes. Resultados: Cinco estudos não relataram a prevalência estratificada por sexo. Apenas dois abordaram molares decíduos segundos hipomineralizados (HSPM). A maioria dos estudos utilizou os critérios da European Academy of Paediatric Dentistry, enquanto outros aplicaram o índice modificado de Defeitos de Desenvolvimento do Esmalte (mDDE). A prevalência variou de acordo com o tamanho da amostra, distribuição por sexo, localização geográfica e ano de publicação. Considerações finais: A HMI apresenta alta prevalência global, com maiores taxas em países com acesso limitado aos cuidados odontológicos. Esses fatores devem ser considerados no planejamento do tratamento.
