Tachmentinhibition; p 0.05), but had no impact on the other strains (p 0.05). Pu-erh tea extracts and chrysanthemum tea extracts, however, lowered the attachment of all Streptococcus strains to cells by involving two and four log CFU/well (999.99 attachment inhibition; p 0.05). The attachment of Actinomyces naeslundii ATCC 51665 to cells was not affected by any of the tea extracts tested (p 0.05). Of particular note is that the extract of chrysanthemum tea, which, as described above, is often a blend of black tea and dried chrysanthemum, had a higher (p 0.05) impact on inhibiting attachment than the black tea extract alone. This suggests that the active compounds in the chrysanthemum tea extract were contributed by the chrysanthemum elements and not the black tea elements from the mix. Pu-erh tea and chrysanthemum tea extracts, which have been found to contain somewhat greater levels of tannin, had a higher effect (p 0.05) than the non-fermented or partially-fermented tea extracts on Streptococcus strains, suggesting that Streptococci may perhaps be much more sensitive to polymeric flavonoids or other big molecule polyphenols with respect to their attachment to HGF-1. Non-fermented or partially-fermented teas, including green tea and oolong tea, have already been previously shown to inhibit the attachment of Streptococcus mutans to collagen and tooth surfaces [12]. As indicated, in our study extracts of those teas only slightly inhibited the attachment of 1 bacterial strain towards the gingival cell line. Additionally, EGCg and gallic acid had been found to possess no considerable effect (p 0.05) around the capacity of all strains to attach to the cell line. This locating suggests a feasible explanation for the relative ineffectiveness with the reduce degree fermented tea extracts (green tea and oolong tea), which are wealthy in these compounds, in inhibiting adhesion. Fibronectin (Fn) is situated on the outer surface in the HGF-1 plasma membrane and acts as a receptor protein for oral bacteria for instance Treponema denticola [21]. Streptococcus mutans and Streptococcus salivarius have wall-associated protein A (wapA) in their outer membrane that permits them to bind collagen plus a wide array of extracellular matrix molecules which includes kind I collagen, laminin, keratin and Fn [22,23].
