Equisetum giganteum influences the ability of Candida albicans in forming biofilms over the denture acrylic resin surface
2017
AbstractContext: Equisetum giganteum L. (Equisetaceae) is an endemic plant of Central and South America used in traditional medicine. Natural drugs have been frequently used in the treatment of a myriad of diseases, proving to be an alternative to synthetic chemicals, and have been intensively studied in the prevention of sicknesses, including oral diseases.Objective: This study evaluated the in vitro antiadherent activity of E. giganteum extract against Candida albicans biofilms.Materials and methods: Crystal violet and colony-forming units assays were used to quantify the total biofilm biomass and biofilm living cells on a denture base acrylic resin pretreated with hydroethanolic extract of E. giganteum in different concentrations (50, 25, 16, 8, and 4 mg/mL), after 24 h of biofilm development.Results: Equisetum giganteum affected biofilms by reduction of biomass and living cells per area of acrylic specimens. The results revealed reduction of 15–44% of the biofilm mass and reduction of numbers of colon...
