Ação do quitosano, própolis e aloé vera na desinfeção em endodontia

: revisão sistemática da literatura

Abstract

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.
