| Abstract: | Objective To observe the antibacterial activities of tea polyphenol against 4 common periodontal bacteria in vitro. Methods The agar dilution method was used to detect the minimal inhibition concentration(MIC) of tea polyphenol against 66 stains of Porphyromonas gingivalis, Prevotella intermedia, Prevotella nigrescens and Fusobacterium nucleatum . Results All bacteria were inhibited by tea polyphenol. For P. gingivalis and P. intermedia, the MIC 50 and MIC 90 values were 125-250mg/L respectively; For P.nigrescens, the MIC value was 125mg/L;For F. nucleatum, the MIC 50 and MIC 90 values were 125-500mg/L and 250-500mg/L respectively. Conclusion All bacteria were susceptible to tea polyphenol. Tea polyphenol is significant for periodontal treatment. |
