A Hipomineralização de Molares e Incisivos (HMI) é um defeito de desenvolvimento do esmalte, de origem multifatorial que afecta de um a quatro primeiros molares permanentes e frequentemente está associada aos incisivos permanentes. Clinicamente se caracteriza como opacidades demarcadas de coloração branco-creme e/ou amarelo-café. Em casos severos pode haver dor, fraturas pós-irruptivas, lesões de cárie dentária e restaurações atípicas. Dentre as opções de tratamento estão as restaurações temporárias com cimento de ionômero de vidro, restaurações em resina composta, coroas, restaurações indiretas e a exodontia. Esta última opção permite que o segundo molar permanente se reposicione espontaneamente desde que realizada a tempo, portanto, é considerada uma alternativa viável e custo-efetiva. O objetivo deste caso foi analisar as considerações diagnósticas de exodontia de primeiros molares permanentes severamente afetados pela HMI. Paciente do sexo feminino, 9 anos de idade, padrão esquelético Classe I, maloclusão Classe I bilateral e HMI severa. Para o tratamento, optou-se por realizar a exodontia dos quatro primeiros molares permanentes sob anestesia geral. Após 10 meses, se observa que os segundos molares permanentes estão clinicamente saudáveis e apresentam inclinações e posicionamentos favoráveis para o fechamento espontâneo do espaço. Conclui-se que a exodontia de primeiros molares permanentes melhora o prognóstico do paciente e para realizá-la requer um trabalho em conjunto com o ortodontista para diagnosticas e planejar individualmente cada caso.
