É amplamente descrito na literatura a resistência do Enterococcus faecalis ao Hidróxido de Cálcio (HC), um dos medicamentos intracanais mais utilizados na Endodontia. Esse patógeno é a espécie dominante nas infecções endodônticas persistentes, apresenta patogenicidade devido a formação de biofilme e consequentemente, resistência aos agentes antibacterianos. Com isso, o objetivo geral desse trabalho é analisar, através de uma revisão integrativa, a atividade antimicrobiana e antibiofilme, das pastas utilizadas como medicação intracanal, em diferentes associações e veículos, frente ao Enterococcus faecalis. Foi realizada uma busca nas bases de dados PubMed, Scielo e Bireme, com artigos limitados aos últimos cinco anos, no idioma inglês, utilizando-se as palavras chaves “endodontic”, “biofilm”, “calcium hydroxide”, sendo obtidos 73 artigos, dos quais 12 foram selecionados após análise crítica de título e resumo, sendo excluídos revisões de literatura, relatos de casos e meta-análises. De acordo com os trabalhos lidos e analisados, dos doze artigos selecionados, oito apresentaram que o HC possui melhores resultados para atividade antibacteriana e potencial antimicrobiano quando associado a outro agentes antimicrobianos. O hidróxido de cálcio isolado apresentou efeito limitado contra o E. faecalis, demonstrando não ser eficaz para eliminar o biofilme. Conclui-se que, a partir desta revisão integrativa, a melhor forma de realizar os tratamentos endodônticos que utilizam o HC como medicação intracanal para erradicação do E.faecalis, é quando esta é usada de forma associada aos veículos com atividade antimicrobiana, mostrando melhores resultados frente à atividade antimicrobiana para eliminação do biofilme.
