Joiner A, Muller D, Elofsson UM, Arnebrant T. Ellipsometry analysis of the in vitro adsorption of tea polyphenols onto salivary pellicles. Eur J Oral Sci 2004; 112: 510–515.© Eur J Oral Sci, 2004The adsorption of components from black tea and of purified tea polyphenols onto a whole unstimulated salivary pellicle-like protein layer, formedin vitroon hydroxyapatite discs, was studied byin situellipsometry. It was found that components from black tea and the purified polyphenols epicatechin-3-gallate (ECG), epigallocatechin-3-gallate (EGCG) and theaflavin readily adsorbed onto the pellicle. Further investigations showed that under the experimental conditions of this study, no black tea- or purified polyphenol-modified pellicles were eluted by either phosphate buffer or sodium dodecyl sulphate rinses.Therefore, black tea and its polyphenol components are indicated to have a profound effect onin vitropellicle modification. Similar effects were observed for tannic acid. [ABSTRACT FROM AUTHOR] |
