Tooth Regeneration Gel Could Replace Painful Fillings
Posted by admin / Under Tooth Painting
Could this new gel be the biggest dental breakthrough since the introduction of fluoride? THE GIST A new gel could soon eliminate painful fillings and root canals. The technology doesn't prevent cavities; it heals teeth by regenerating them. Although this is good news for teeth, the research could also be applied to heal bones and other tissues in the body. Dentists could soon hang up their drills. A new peptide, embedded in a soft gel or a thin, flexible film and placed next to a cavity, encourages cells inside teeth to regenerate in about a month, according to a new...

Gel that can help decayed teeth grow back could end fillings
Posted by admin / Under Tooth Painting
Open wide: Thanks to a new gel, soon this won't hurt A gel that can help decayed teeth grow back in just weeks may mean an end to fillings. The gel, which is being developed by scientists in France, works by prompting cells in teeth to start multiplying. They then form healthy new tooth tissue that gradually replaces what has been lost to decay. Researchers say in lab studies it took just four weeks to restore teeth back to their original healthy state. The gel contains melanocyte-stimulating hormone, or MSH. We produce this in the pituitary gland, a pea-sized gland...

Parents Pull Child's Tooth With RC Car
Posted by admin / Under Tooth Painting
Health-care reform might have become just another political ploy to earn votes come Election Day up on Capitol Hill -- but it's causing some parents to resort to Middle Ages-style medicine that even Theodoric of York wouldn't prescribe. We don't know if the lack of adequate dental care in the country forced these two parents to pull their child's loose tooth out the "Radio Shack way" -- tying one end of a string around the tooth and another to the end of a remote-controlled car and sending it barreling toward a makeshift ramp at Mach 2 -- but we're pretty...

Neandertals Ate Their Veggies, Tooth Study Shows
Posted by admin / Under Tooth Painting
Neandertals Ate Their Veggies, Tooth Study ShowsSara Goudarzi for National Geographic NewsApril 28, 2008 Tiny bits of plant material found in the teeth of a Neandertal skeleton unearthed in Iraq provide the first direct evidence that the human ancestors ate vegetation, researchers say. Little is known about diet of Neandertals (also spelled Neanderthals), although it's widely assumed that they ate more than just meat. Much of what is known about their eating habits has come from indirect evidence, such as animal remains found at Neandertal sites and chemical signatures called isotopes detected in their teeth. The new hard evidence is...

Experimental chewy mint beats tooth decay
Posted by admin / Under Tooth Painting
Experimental chewy mint beats tooth decay 09th April 2008 A new chewable mint looks set to solve the worldwide problem of tooth decay. BasicMints is an experimental fluoride-free treatment designed to mimic a component in human saliva that neutralises acids in the mouth that can erode tooth enamel. US researchers tested the product on 200 children – aged between 10-and-a-half and 11 – over a year. The results show that children who were administered BasicMints had 62% fewer cavities in their molars when the year was up, compared to children in the placebo group. The research team, from New York's...

First Europeans Came From Asia, Not Africa, Tooth Study Suggests
Posted by admin / Under Tooth Painting
Europe's first early human colonizers were from Asia, not Africa, a new analysis of more than 5,000 ancient teeth suggests. Researchers had traditionally assumed that Europe was settled in waves starting around two million years ago, as our ancient ancestors—collectively known as hominids—came over from Africa. But the shapes of teeth from a number of hominid species suggest that arrivals from Asia played a greater role in colonizing Europe than hominids direct from Africa. These Asian hominids may have originally come from Africa, the scientists note, but had evolved independently for some time. (Related: "Did Early Humans First Arise in...
