When the time comes to get relief from a dental problem, we are all glad that dentistry has come so far—much of the progress based on research supported by NIH’s National Institute of Dental and Craniofacial Research. Still, almost no one looks forward to getting a root canal. Not only can the dental procedure be uncomfortable and costly, there’s also a risk of failure due to infection or other complications. But some NIH-supported researchers have now come up with what may prove to be a dazzling strategy for reducing that risk: nanodiamonds!

That’s right, these researchers decided to add tiny diamonds—so small that millions could fit on the head of the pin—to the standard filler that dentists use to seal off a tooth’s root. Not only are these nanodiamonds extremely strong, they have unique properties that make them very attractive vehicles for delivering drugs, including antimicrobials that help fight infections of the sealed root canal.

NIH Common Fund: 10 Years of Transformative Science

Common Fund 10th Anniversary LogoHappy 10th Anniversary to the Common Fund! It’s hard to believe that it’s been a decade since I joined then-NIH Director Elias Zerhouni at the National Press Club to launch this trans-NIH effort to catalyze innovation and speed progress across many fields of biomedical research.

We’re marking this milestone with a special celebration today at NIH’s main campus. And, for those of you who can’t make it to Bethesda to join in the festivities, you can watch the videocast (live or archived). But allow me also to take this opportunity to share just a bit of the history and a few of the many achievements of this bold new approach to the support of science.
