Para o sucesso do tratamento endodôntico é fundamental associar à instrumentação mecânica uma eficiente irrigação capaz de eliminar bactérias dentro dos canais radiculares. Nesta perspetiva o uso do Hipoclorito de Sódio tem sido reconhecido como o irrigante endodôntico gold standard pois apresenta uma elevada capacidade de dissolução de tecido necrosado e de matéria orgânica, baixa tensão superficial e excelente bactericida a baixo custo. Embora a sua utilização seja considerada segura, a toxicidade do Hipoclorito de Sódio não deve ser ignorada. Quando em contacto com tecidos vivos pode provocar complicações graves. Portanto, é crucial que os médicos dentistas estejam cientes dos riscos associados e adotem medidas preventivas, incluindo a implementação de um plano de tratamento adequado. O objetivo desta revisão bibliográfica é realizar uma abordagem sobre os acidentes envolvendo o Hipoclorito de Sódio durante o tratamento endodôntico, explorando propriedades, complicações, alternativas à sua utilização, medidas preventivas e conduta apropriada nessas situações.
For the success of endodontic treatment, it is essential to associate efficient irrigation with mechanical instrumentation capable of eliminating bacteria within the root canals. From this perspective, the use of Sodium Hypochlorite has been recognized as the gold standard endodontic irrigant as it has a high capacity for dissolving necrotic tissue and organic matter, low surface tension and excellent bactericide at low cost. Although its use is considered safe, the toxicity of Sodium Hypochlorite should not be ignored. When in contact with living tissue it can cause serious complications. Therefore, it is crucial that dentists are aware of the associated risks and adopt preventive measures, including implementing an appropriate treatment plan. The objective of this literature review is to provide an approach to accidents involving Sodium Hypochlorite during endodontic treatment, exploring properties, complications, alternatives to its use, preventive measures and appropriate conduct in these situations.
