Scientists detect tooth decay in the 3rd dimension

A team of scientists from Glasgow today revealed a new technique that will allow dentists to detect and study the tell-tale signs of tooth decay before too much damage is done. Speaking at one of the opening sessions at the Institute of Physics conference Photon 04 in Glasgow, Simon Poland outlined a new way of making a detailed 3D picture of a diseased area of a tooth, which could be done while a patient waits.
