Resumo(s)
Introdução: O retratamento endodôntico não cirúrgico é um procedimento terapêutico que pode corrigir falhas dos tratamentos endodônticos anteriores removendo o material de obturação, reinstrumentação, desinfecção e preenchimento dos canais radiculares. No entanto, a remoção completa da guta percha e dos materiais de obturação ainda representa um desafio. Recentemente, os lasers foram propostos como uma alternativa ou complemento ao tratamento endodôntico convencional e podem desinfectar e remover resíduos intracanais. Objetivo: Analisar criticamente, na literatura, a eficácia dos novos métodos inovadores, focando a atenção nos lasers e buscar evidências que demostrem sua eficácia na remoção de material obturador nos retratamentos endodônticos. Materiais e métodos: A pesquisa foi conduzida nas bases de dados: PubMed/MEDLINE, Dentistry & Oral Sciences Source, Web of Science, Cochrane Library, Scopus e ProQuest Dissertations & Theses. De seguida, <br/>realizou-se a seleção dos artigos através dos critérios de inclusão e exclusão. Os termos MeSH foram interligados com os operadores booleanos AND e OR. Resultados: Os resultados mostraram que os lasers podem reduzir significativamente a quantidade de material de obturação remanescente e, em alguns casos, reduzir o tempo necessário para o retratamento. Mas nenhum dos métodos remove completamente a gutta-percha e os materiais de obturação. Conclusão: Os lasers são uma alternativa promissora para a remoção de materiais de obturação em retratamentos endodônticos não cirúrgicos. Mais estudos clínicos controlados com métodos padronizados são necessários para confirmar a eficácia, segurança e aplicabilidade clínica.
Introduction: Non-surgical endodontic retreatment is a therapeutic procedure aimed at correcting failures of previous endodontic treatments through the removal of filling materials, reinstrumentation, disinfection, and refilling of the root canal system. However, the complete removal of gutta-percha and root canal filling materials remains a clinical challenge. Recently, lasers have been proposed as an alternative or adjunct to conventional endodontic treatment due to their ability to disinfect root canals and remove intracanal remnants. Objective: To critically evaluate, in the literature, the effectiveness of innovative methods, with a particular focus on laser technology, and to identify evidence supporting its efficacy in the removal of root canal filling materials during endodontic retreatment. Materials and Methods: A literature search was conducted in the following databases: PubMed/MEDLINE, Dentistry & Oral Sciences Source, Web of Science, Cochrane Library, Scopus, and ProQuest Dissertations & Theses. Studies were selected according to predefined inclusion and exclusion criteria. MeSH terms were combined using the Boolean operators AND and OR. Results: The findings demonstrated that laser systems can significantly reduce the amount of residual filling material and, in some cases, decrease the time required for retreatment procedures. Nevertheless, none of the evaluated methods was capable of completely removing gutta-percha and root canal filling materials. Conclusion: Lasers represent a promising alternative for the removal of root canal filling materials during non-surgical endodontic retreatment. However, further controlled clinical studies with standardized methodologies are required to confirm their effectiveness, safety, and clinical applicability.
