Effects of sodium polystyrene sulfonate on gingival plaque: microbiological investigation and clinical follow-up.
A new antiplaque agent was tested on nine subjects. The antiplaque agent, a 5% aqueous solution (p/v) of sodium polystyrene sulfonate, applied on the tooth surfaces by daily topical application for two weeks, caused a statistically significant 30% reduction of plaque index (PI), with corresponding reduction of total bacteria and qualitative modifications of plaque formation with reduction of Gram-negative bacteria.
