Figure 1From: Inhibition of attachment of oral bacteria to immortalized human gingival fibroblasts (HGF-1) by tea extracts and tea componentsEffects of extracts and compounds on oral bacterial attachment. Effect of tea extracts (a) and EGCg and gallic acid (b) on oral bacterial attachment to the HGF-1 gingival cell line (log CFU/cm2, nā=ā3). Values labeled with the same letter are not significantly different (pā>ā0.05) among the treatments within a strain. Tukeyās comparisons were conducted separately for each strain. The * symbol indicates that the attachment of Streptococcus salivarius was significantly different from that of Streptococcus mitis (pā<ā0.05).Back to article page
