The Nano Structure of Enamel
Cavities are on the rise. If you’re an adult you’ve probably got one now. The World Health Organization says nearly 100 percent of adults suffer from them. And some 60 to 90 percent of children have them, too.
Yes, we can blame it on the soda, the candy, the chocolate-chip scones, and what have you. But to really get in there and fix the problem, we have to know how and why these things penetrate enamel. And to understand that, you have to understand enamel.
Julie Carney, a professor of material and structures engineering at Australia’s University of Sydney, has managed to take a good look at the hard shiny stuff at the atomic level using a new microscopy technique. Atom probe tomography, as it’s known, “allows us to reconstruct exact positions of atoms within matter,” says Carney.
After experimenting on her child, Cairney may turn to examining areas of decay. Such an investigation may be a bit trickier, however. Atom probe tomography works best on very dense stuff and a piece of decayed tooth may be a bit too holey on the atomic scale as well as the macro.
