    Nosebleeds are common among children and young adults, but one young man's frequent nosebleeds turned out to have a rather unusual cause: He had a tooth in his nose, according to a new report of his case. After suffering from nosebleeds once or twice a month for three years, the 22-year-old man in Saudi Arabia consulted a doctor, who found an ivory-white, bony mass, about half an inch (1 centimeter) long in the man's nose. The doctors then consulted with dentist colleagues, who concluded that the mass was actually an extra tooth that had somehow ended up growing in his...

    An international team of scientists led by Prof Cheng-Ming Chuong from the University of Southern California has discovered unique cellular and molecular mechanisms behind tooth renewal in American alligators (Alligator mississippiensis).Their findings, published in the Proceedings of the National Academy of Sciences, pave the way for tooth regeneration in people. “Humans naturally only have two sets of teeth – baby teeth and adult teeth. Ultimately, we want to identify stem cells that can be used as a resource to stimulate tooth renewal in adult humans who have lost teeth. But, to do that, we must first understand how they renew...

Thus, Robert Ester, 46, of Worcester came to be standing before a judge yesterday for allegedly stealing another man’s grill, Springfield police said.

    JERUSALEM – Israeli archaeologists said Monday they may have found the earliest evidence yet for the existence of modern man, and if so, it could upset theories of the origin of humans. A Tel Aviv University team excavating a cave in central Israel said teeth found in the cave are about 400,000 years old and resemble those of other remains of modern man, known scientifically as Homo sapiens, found in Israel. The earliest Homo sapiens remains found until now are half as old.

    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...

    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...

    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...

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 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...

    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...

    Epileptic seizures sparked by tooth brushing 09:00 06 March 2007 NewScientist.com news service Rachel Nowak “Brushing your teeth is very rhythmic. Our idea is that it causes a rhythmic over-activity in the brain, which feeds back on itself – similar to the effect of strobe lighting on people with photosensitive epilepsy,” says neurologist Wendyl D’Souza of St Vincent’s Hospital in Melbourne, Australia, one of the team reporting the cases. Epilepsy occurs when nerve cells in an area of the brain fire more rapidly than usual and in synchrony with one another. This causes seizures that range from “grand mal” seizures...

    WASHINGTON - Twelve-year-old Deamonte Driver died of a toothache Sunday. A routine, $80 tooth extraction might have saved him. If his mother had been insured. If his family had not lost its Medicaid. If Medicaid dentists weren't so hard to find. If his mother hadn't been focused on getting a dentist for his brother, who had six rotted teeth. By the time Deamonte's own aching tooth got any attention, the bacteria from the abscess had spread to his brain, doctors said. After two operations and more than six weeks of hospital care, the Prince George's County boy died. Deamonte's death...

    Stem cells from may help scientists grow parts of teeth you may need in the future. Researchers from University of Southern California School of Dentistry have regenerated tooth roots and ligaments to restore tooth function in pigs. They believe this breakthrough looks very promising to use in people. Scientists used stem cells harvested from the extracted wisdom teeth of 18-to 20-year-olds to create enough root and ligament structure to support the restoration of a crown in their pig model. The restoration was similar to the original tooth in function and strength. The technique uses stem cells harvested from the root...

A joint team of scientists from the institute and Osaka University succeeded in repairing damaged liver and bones in rats using stem cells taken from wisdom tooth germ. The finding raises hopes of developing regenerative medicine using wisdom teeth germ taken from people during orthodontic treatments. Tooth germ disappears as a tooth is formed, but that of a wisdom tooth stays in...

Now it is a jagged black stump, and the pain gnawing at Mr. Kelly's mouth has transferred itself to a different tooth, mottled and rickety, on the other side of his mouth.

Nweeia, a clinical instructor in restorative dentistry and biomaterials sciences at HSDM, will be presenting his conclusions at the 16th Biennial Conference on the Biology of Marine Mammals in San Diego. The narwhal has a tooth, or tusk, which emerges from the left side of the upper jaw and is an evolutionary mystery...

In the winter months of 2004, McDonald photographed tracks left by a large animal on a mud-covered Loch Ness shoreline...
