Abstract
Compositions and methods for preventing the attachment of dental plaque to the surfaces of the teeth of mammals comprise condensation polymers of formaldehyde with naphthalene sulfonic acid as well as the pharmaceutically acceptable salts thereof in a pharmaceutically acceptable vehicle, and the periodic application thereof of teeth.
Claims8
An oral hygiene composition comprising an effective amount for preventing deposition of dental plaque on teeth of a sulfonated condensation polymer of formaldehyde with naphthalene, said polymer having repeating units of structure:
- ##STR3## wherein M is selected from the group consisting of lithium, sodium, potassium, calcium, magnesium, zinc, aluminum, hydrogen, ammonium, and substituted ammonium ions derived from pharmaceutically acceptable organic amines, and p has an average value in the range of from about 0.4 to about 1.4, said polymer having a molecular weight in the range of from about 500 to about 5,000, in a pharmaceutically acceptable oral hygiene vehicle compatible with said polymer.
