The antibacterial properties of eucalyptus oil against two main oral disease pathogens antibacterial pathogen dentalhealth oralhealth eucalyptus eucalyptusoil essentialoil
By Hugo Francisco de SouzaJul 11 2023Reviewed by Danielle Ellis, B.Sc. In a recent study published in the journal BDJ Open, researchers tested the efficacy of Eucalyptus oil again two bacteria responsible for dental caries. This work elucidates that Eucalyptus oil could serve as a natural alternative to chlorhexidine. Eucalyptus oil displayed significant anti-bacterial properties against both the planktonic- and more antibiotic-resistant biofilm forms.
Searches for an alternative have proposed herbal and natural compounds as viable alternatives to chlorohexidine. However, these compounds remain understudied, with only a few studies investigating the antimicrobial characteristics of Eucalyptus oil . About the study In this study, researchers evaluate the efficacy of EO extracts dilutions of EO extract against cultures of S. mutans and E. faecalis, in controlled in-vitro conditions. Researchers began by culturing the bacteria overnight in brain-heart infusion broth. They then standardized for bacterial concentration and added aliquots of the cultures to experimental groups containing mixtures of EO, BHI, and 2% sucrose or controls without EO in the mix.
Study findings Planktonic forms of S. mutans were observed to have an almost 14-fold lower concentration in wells treated with EO, as compared to their controls. Biofilm forms showed even greater 61-fold reductions, suggesting that EO is a prime candidate to combat caries-related pathogens. “The results of this study should be interpreted carefully, as the use of conventional preventive and therapeutic approaches must still be the gold standard in preventing biofilm-triggered diseases.”
