A first conduit conducts compressed air from the compressor into the container. The compressed air is at a pressure of between about 20psi to about 50psi. A second conduit conducts the slurry and air from the container to an applicator from which the slurry and air is sprayed into the oral cavity of a human. The second conduit is at least about 24 inches in length.</p> |
