Introdução:
Em endodontia, estirpes resistentes como Candida albicans e Enterococcus faecalis, são cada
vez mais colonizadoras dos canais radiculares. O hipoclorito de sódio é o irrigante mais utilizado
na desinfeção dos canais, no entanto apresenta algumas limitações. Deste modo, tem vindo a
surgir na literatura novos produtos naturais como possíveis alternativas ou coadjuvantes dos
produtos já comummente utilizados, para que seja possível alcançar melhores resultados na
desinfeção dos canais radiculares.
Objetivos:
Analisar, na literatura, evidência científica sobre a eficácia de compostos naturais como Própolis,
Aloé Vera e Quitosano, na desinfeção canalar e na eliminação de Enterococcus faecalis e
Candida albicans, comparando com o hipoclorito de sódio.
Materiais e métodos:
Foi realizada uma pesquisa nas bases de dados Medline/PubMed®, Cochrane Library e Web of
Science®, até março de 2021, utilizando diferentes termos de pesquisa. Da pesquisa obtida,
foram selecionados os artigos que seriam importantes para ler na integra. Posteriormente os
dados relevantes foram colocados em forma de tabela, de forma a serem analisados.
Resultados:
Dos 14 artigos incluídos neste estudo, em 2, o quitosano apresentou uma maior eficácia do que
o hipoclorito de sódio na eliminação de Enterococcus faecalis. Apenas 1 artigo não encontrou
diferenças significativas entre o hipoclorito de sódio e o quitosano na redução de microrganismos.
Em todos os outros artigos, o hipoclorito de sódio apresentou uma eficácia superior.
Conclusão:
O hipoclorito de sódio foi, na maioria dos estudos, a substância mais eficaz na desinfeção dos
canais radiculares. Contudo, os produtos naturais analisados também apresentaram alguma
eficácia ao nível da eliminação de microrganismos, concluindo assim que, apesar de não serem
tão eficazes, podem ser utilizados como substâncias coadjuvantes àquelas já atualmente
utilizadas. Mais estudos serão necessários para analisar outros produtos naturais que possam
servir como desinfetantes endodônticos.
Introduction: In endodontics, resistant strains such as Candida albicans and Enterococcus faecalis are increasingly colonizing root canals. Sodium hypochlorite is the most used irrigant for the disinfection of canals, however it has some limitations. Thus, new natural products have been appearing in the literature as possible alternatives or adjuvants to products already commonly used, so that it is possible to achieve better results in the disinfection of root canals. Objectives: Analyze in the literature, scientific evidence on the effectiveness of natural compounds such as Propolis, Aloe Vera and Chitosan, in canal disinfection and elimination of Enterococcus faecalis and Candida albicans, compared to sodium hypochlorite. Materials and Methods: A search was carried out in the Medline/PubMed®, Cochrane Library and Web of Science® databases, until March 2021, using different search terms. From the research obtained, articles that would be important to read in full were selected. Subsequently, the relevant data were placed in table form, in order to be analyzed. Results: Of the 14 articles included in this study, in 2, chitosan was more effective than sodium hypochlorite in eliminating Enterococcus faecalis. Only 1 article found no significant differences between sodium hypochlorite and chitosan in reducing microorganisms. In all other articles, sodium hypochlorite showed superior efficacy. Conclusion: In most studies, sodium hypochlorite was the most effective substance in disinfecting root canals. However, the natural products analyzed also showed some effectiveness in terms of eliminating microorganisms, thus concluding that, despite not being as effective, they can be used as supporting substances to those already used. More studies will be needed to analyze other natural products that can serve as endodontic disinfectants.
