ABSTRACT
Objective:
To observe the inhibition of Chinese gallnut on bacteria in plaque biofilms by the use of artificial mouth.Methods:
Water extract of Chinese Gallnut was prepared and liquid media two-fold dilution method was used to determine the minimal inhibition concentration(MIC)of the drug on S.mutans,A.viscosus,S.sanguis and S.oralis.Individual bacteria plaque biofilms in artificial mouth were created.The inhibition of Chinese gallnut on the bacteria in plaque biofilms was studied by colony counting.Results:
In bacteria suspension gallnut water extract inhibited the growth of the four kinds of bacteria.The MIC of the extract on S.mutans,A.viscous and S.sanguis was 64 mg/ml,that on S.oralis 8 mg/ml.The plaque biofilms formed by the four kinds of bacteria could be inhibited by 2 mg/ml-128 mg/ml of the extract dose-dependently.At the highest tested conentration(128 mg/ml)the gallnut water extract could not completely clear up the colonyforming unite(CFU)of the becteria.Conclusion:
Chinese gallnut water extract can inhibit the growth of bacteria in suspension and in plaque biofilms,the bacteria in biofilms may have stronger resistance to the extract.
