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.
