Scientists have uncovered new information about the Denisovans, a mysterious group of human relatives that interbred with ancient humans in Asia.

The Denisovans had very large and unusual teeth, unlike those of humans or Neanderthals, reports an international team from Germany, Canada and Russia.

While individuals have different tooth sizes, finding two teeth this large from two different, unrelated individuals suggests "the whole group probably had very large and weird teeth."

They also likely had a very large and robust jaw to support such long tooth roots. But aside from that, we know nothing about what they looked like.

Teeth in the news again, and once again, it's sports related.

Sports, technology, and archaeology seem to be among the highest volume generators of newsworthy teeth topics.

Wolfing down your meal prevents you from really tasting it. When a dog does that, we like to say, "Did you taste any of it?"

As a high tech dentist, I use only what has been proven safe and effective in clinical trials. But the dental technology realm is exploding just like many other fields, as science advances inexorably.

http://news.usc.edu/88721/how-to-eliminate-pain-associated-with-tooth-decay/

From the article:

Dual discoveries at USC propose a promising method to regrow nonliving hard tissue, lessening or even eliminating pain associated with tooth decay, which the National Institutes of Health calls the most prevalent chronic disease.

Janet Moradian-Oldak, a professor at the Herman Ostrow School of Dentistry of USC, has investigated methods to regrow tooth enamel for the past two decades. The process is especially tricky because unlike bone, mature enamel cannot rejuvenate. Tooth enamel is a nonliving tissue.

The a-ha moment came Oct. 22 when, in collaboration with lead author Sauma Prajapati of USC and other colleagues, she published a study in the Biomaterials journal saying matrix metalloproteinase-20, an enzyme found only in teeth, chops up amelogenin proteins, which facilitate organized enamel crystal formation. MMP-20 clears the way for hard material to usurp vacated space.

Her team is the first to define the function of an enzyme for preventing protein occlusion inside a crystal, she said.

Sometimes a new dental technology arises, but a practicing dentist must wait to see if something is scientifically proven by unbiased clinical studies, and not rush into every new trend.

http://www.engadget.com/2015/11/09/dental-cavity-regrow-procedure/

Scientists in Britain have developed a new procedure dubbed EAER, or "Electrically Assisted Enhanced Remineralisation," that can repair a slightly decayed tooth before a deep cavity forms.

The supposedly painless procedure involves cleaning (not drilling) the tooth of any signs of mild decay, then flushing it with minerals and stimulating it with an electric pulse.

This pushes the minerals into the deepest part of the lesion and speeds up a naturally occurring process called "remineralization".

This is where minerals in your saliva and some foods enter the tooth enamel and make it stronger.

Vermont’s deer hunting rifle season begins on Saturday morning.

This year, the Department of Fish and Wildlife is asking hunters to send them the middle incisor teeth of deer that are killed.

Middle incisor tooth is the standard for aging deer, says Deer Project Leader Nick Fortin. The teeth are sent to a lab, which cross section them and determine the age. It’s similar to counting the rings on a tree, Fortin explained.
