Outline of Final Research Achievements

Essential oils are known for their antifungal activities and efficacy in the treatment of oral candidiasis. This study evaluated whether the essential oils could be used to denture cleaning. Tea tree oil (1.0%) and lemon grass (0.5%, 1.0%) produced significantly higher results than water in the effect of removing biofilms adhering to denture base resin. The surface roughness of specimens after brushing with these essential oils was significantly lower than that of those after brushing with water. It was suggested that these essential oils would be desirable and useful to use for denture cleaning.
