endodontia, retratamento, periodontite apical, dor pós-operatóriaResumo
O objetivo do estudo foi avaliar a eficácia do retratamento endodôntico não cirúrgico na resolução da periodontite apical, considerando a redução bacteriana, o controle da dor pós-operatória e a cicatrização periapical. Foram analisados 35 artigos selecionados no PubMed, Scopus e Embase até outubro de 2024, aplicando-se critérios de inclusão e exclusão. Os estudos analisados abrangeram protocolos de desinfecção (hipoclorito de sódio, clorexidina, laser e irrigantes ozonizados), técnicas de obturação, taxas de sucesso e fracasso, além da eliminação de microrganismos resistentes, como Enterococcus faecalis e Fusobacterium nucleatum. Os resultados indicam que o uso de tecnologias avançadas, como o laser de diodo de 980 nm e os irrigantes ozonizados, potencializa a desinfecção e favorece a reparação periapical. Da mesma forma, a ativação ultrassônica e manual dos irrigantes mostrou-se eficaz na redução bacteriana e no alívio da dor pós-operatória; no entanto, a heterogeneidade dos protocolos demonstra a necessidade de estabelecer diretrizes padronizadas baseadas em evidências para otimizar os resultados. Em conclusão, o retratamento endodôntico não cirúrgico constitui uma alternativa eficaz para o tratamento da periodontite apical, especialmente quando se empregam métodos modernos de desinfecção; no entanto, são necessárias mais pesquisas para consolidar a prática clínica.
