Abstract

ObjectiveThe adherence of Candida to mucosal surfaces is the initial step for successful invasive process of the oral cavity. The study aimed to investigate the effect of two plant extracts on the non-specific and specific bindings of oral candida.MethodsIn the former, adsorption to hexadecane was used to measure the hydrophobic interaction of the candida cells. In the later, glass beads coated with saliva represented the experimental pellicles in specific adhesion of oral candida to hard tissue surface.ResultsCandida krusei, Candida dubliniensis and Candida tropicalis showed the highest adsorption to hexadecane at 30.23%, 26.19% and 19.70%, respectively, while the others within the range of 7-10%. All candidal species were significantly affected by the extracts (P < 0.05) with Brucea javanica exhibited more than 60% reduction of CSH than Piper betle. Candida parapsilosis showed the highest affinity in specific-bindings to pellicle with 18.72 ± 0.71 × 105 CFU/ml. Exposing to P. betle-treated pellicle has drastically reduced the adherence of C. tropicalis, Candida albicans and C. krusei by 86.01%, 61.41% and 56.34%, respectively. B. javanica exhibited similar effect on C. tropicalis (89.86%), Candida lusitaniae (88.95%), C. albicans (79.74%), Candida glabrata (76.85%) and C. krusei (67.61%).ConclusionThe extracts demonstrated anti-adherence activities by modifying the CSH and the characteristics of the experimental pellicle.
