Summary for Patent: 5,192,362
Title: Dentine protection
Abstract:To combat the accumulation of plaque on dentures, a non self-supporting coating of a non-toxic, negatively charged polysaccharide is applied. The polysaccharide coating is gradually sacrificed or ablated during wear. Ablation appears to remove microorganisms along with coating material. The polysaccharide is further defined by an ability to reduce the adhesion of Streptococcus salivarius cells in a simple in vitro bacterial adhesion test by at least 25% over a control.
