Abstract
The adherence of three Candida species to human buccal epithelial cells (BEC) following treatment with different concentrations of date extract was investigated in vitro, as well as the effect of a mouth rinse with date extract on the adhesion of yeast to BEC. Adhesion of C. albicans, C. tropicalis and C. kefyr to BEC was significantly reduced after both short- and long-term periods of yeast exposure to various concentrations of date extract (reduction between 25% and 52% of the control value). A similar inhibition of adherence was observed upon pre-incubation of BEC with date extract. There was a significant reduction (P<0.001) in the adherence of yeast to BEC collected immediately or 5-20 min after an oral rinse with 10% date extract. No statistically significant difference was observed in the adhesion of BEC collected 30 min after an oral rinse with date extract and control BEC. In addition, pre-treatment of either Candida or BEC, or both, with date extract resulted in reduced adherence, the magnitude of which was largest when both types of cells were pre-treated. Date extract also inhibited germ-tube formation of C. albicans (56-85% inhibition), which might contribute to the effects on adherence.
