Study on antimicrobial effect of the mixture of Chinese medicine-chitosan to Candida albicans and the possibility as denture adhesive

Abstract

Abstract: PURPOSE: To observe the antimicrobial effect and the tensile bond strength of water-soluble chitosan after adding different Chinese medicines to Candida albicans. METHODS: The extract of 6 kinds of Chinese medicine by decoction in different concentrations were mixed with chitosan, and the most effective mixture inhibiting Candida albicans and the minimal inhibitory concentration (MIC) were explored; Then the tensile bond strength of the mixture was tested and compared with Protefix denture adhesive. The data was analyzed with SPSS17.0 software package. RESULTS: The antibacterial effect of polyphylla-chitosan mixture was the best among the 6 kinds of Chinese medicine- chitosan mixture, and its MIC was 1.563 mg/mL. The tensile bond strength of polyphylla-chitosan mixture at 0 h and 12 h when immersed in artificial saliva were significantly larger than Protefix denture adhesive. The average value and the maximum value was significantly greater than the Protefix denture adhesive (P<0.05). CONCLUSIONS: Polyphylla-chitosan mixture has good antibacterial effect on Candida albicans and large tensile bond strength.
