Quotables
"To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth--all that constitutes a wild dream worthy of Jules Verne. I am bold enough to say that such a man-made voyage will never occur regardless of all future advances."
Lee deForest, American radio pioneer ; 1957

The exterior of the particle is water-stable. The particles may be coated on dental floss or the bristles of a toothbrush, or incorporated into an oral rinse. Once placed in the mouth, the degradable material degrades to cause release of the anti-microbial agent, resulting in the inhibition of bacteria in the mouth.Other References
