作者通过对绿茶多酚防龋涂膜抑菌效果的观察，发现绿茶多酚防龋涂膜对变形链球菌、远缘链球菌及乳酸杆菌具有明显的抑制作用，生长实验显示变形链球菌及远缘链球菌的生长抑制率与绿茶多酚防龋涂膜的浓度成正比，证明绿茶多酚防龋涂膜具有一定的防龋作用。 The author through the green tea polyphenols anti-caries coating antibacterial effect observed and found that green tea polyphenols anti-caries film on Streptococcus mutans, Streptococcus sobrinus and Lactobacillus significantly inhibited the growth experiments showed Streptococcus mutans and far Streptococcus sobrinus growth inhibition rate and green tea polyphenols anti-caries coating concentration is proportional to that green tea polyphenols anti-caries coating has a certain anti-caries effect.
