A new antiplaque agent was tested on nine subjects. The antiplaque age
nt, a 5% aqueous solution (p/v) of sodium polystyrene sulfonate, appli
ed on the tooth surfaces by daily topical application for two weeks, c
aused a statistically significant 30% reduction of plaque index (PI),
with corresponding reduction of total bacteria and qualitative modific
ations of plaque formation with reduction of Gram-negative bacteria.
