Attentive followers of dentistry developments that we are, we've been following the story of the plasma brush for awhile now. And it seems like it's making some serious progress: human clinical trials are supposed to begin in early 2012, and there's also a video (below) of the World's Bravest Dentist shooting a plasma beam into his own mouth.
A new tooth-regenerating paste could reverse bacterial-induced tooth decay, sweeping dental drills into the dustbin of history. Hopefully.
As your hygienist probably told you, tooth decay happens when bacteria in plaque dissolve your enamel, creating cavities. Eventually the cavity gets big enough that your dentist has to take out the decay and drill a hole that can be filled with resin, gold or something else. But a new treatment developed at the University of Leeds in the UK reverses the decay, allowing your teeth to rebuild themselves.
Meet the Durrell’s vontsira (Salanoia durrelli). It ain’t pretty, but this small, mongoose-like critter—pronounced “voontseera”—has the distinction of being the first carnivorous mammal discovered in 24 years. The last was the related Grandidier’s vontsira, which, like the new creature, was found on Madagascar.
Scientists must really dread the dentist -- they're always coming up with new solutions to help people avoid that cursed drill. The latest: a hormone gel that regenerates tooth cells in as little as a month.
The gel, the first of its kind, could eliminate the need to fill cavities or drill into the root canal of an infected tooth, Discovery News reports. It is reported in the journal ACS Nano.
Bacteria love hanging out between your teeth—food gets caught there, and brushing can’t reach all the germs. If the bugs settle in and form a cavity, your dentist must drill through your tooth just to get at it. But now dentists can trade their drills for a simple treatment that stops early-stage cavities.
Just the sound of a dentist's drill is enough to send most people into a panic. Add to that the awful inconvenience of walking around for a day with half your face numb, and it's easy to see why getting a cavity filled or a tooth replaced is one of life's most annoying chores. Fortunately, some new research may make the common drill-and-fill a thing of the past.
