They are associated with transporting hot or cold sensitivity to the tooth nerve. For years, scientists have debated the exact nature of the worm-like structures, which were photographed in clear detail by Ru-Ching Hsia, director of the electron microscope core facility at the School......"........ more here, note the photo: www.sciencedaily.com/releases/2009/07/090727205901.htmlooks like a nanotube to me! skyship
