Modulation of bacterial binding to salivary pellicle by treatment with hydrophilizing compounds.
Two hydrophilizing agents, a branched polyethylene glycol derivative and a non-ionic cellulose ether (EHEC) bind to buffer-treated hydroxyapatite and prevent attachment of Streptococcus mutans. EHEC gives a more efficient surface modification, presumably due to a more complete surface coverage. Neither of the 2 hydrophilizing agents were effective on hydroxyapatite which had been pre-treated with saliva. In a small clinical trial, EHEC was found to be moderately effective in preventing plaque formation.
