Salivary melatonin may play an important role in maintaining periodontal health, according to a new study published in the Journal of Periodontology. view more (2006-09-13)
NIST/University Team Records Rare Glimpses of Light from Neutrons
Researchers from the Commerce Department's National Institute of Standards and Technology (NIST) and four universities have made the first experimental observation of rare particles of light emitted during the radioactive decay of the neutron, a key building block of matter. view more (2006-12-21)
Cigarette smoking nearly doubles risk for root canal treatment
According to a new study appearing in the April issue of the Journal of Dental Research, cigarette smoking can lead to not only tooth discoloration and gum disease, but also a common dental procedure that helps to heal a diseased tooth-the root canal. view more (2006-02-24)
Researchers seek to make cavity-causing bacteria self-destruct
Bacteria that eat sugar and release cavity-causing acid onto teeth may soon be made dramatically more vulnerable to their own acid. Researchers have identified key genes and proteins that, if interfered with, can take away the ability of a key bacterial species to thrive as its acidic waste builds up in the mouth. view more (2008-01-03)
Time reversal in the real world
If time went backwards life would look like a video recording played in reverse - or would it? New findings demonstrate that this common assumption may not hold true. Experiments showing for the first time that time is not symmetrical are explained today by Dr John Fry from the University of Liverpool at the British Association Festival of... view more...

New tooth enamel dating technique
The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and 1960s is providing forensic scientists with a more precise way to determine a person's age at the time of death. view more (2005-09-15)
Structural biology scores with protein snapshot
In a landmark technical achievement, investigators in the Vanderbilt Center for Structural Biology have used nuclear magnetic resonance (NMR) methods to determine the structure of the largest membrane-spanning protein to date. view more (2009-06-26)
U of A researcher has rare evidence of dinosaur cannibalism
University of Alberta researcher Phil Bell has found 70 million year old evidence of dinosaur cannibalism. view more (2009-10-07)
Marine Biology Mystery Solved: Function of "Unicorn" Whale's 8-foot Tooth Discovered
Today, Harvard School of Dental Medicine (HSDM) researcher Martin Nweeia, DMD, DDS, answers a marine science question that has eluded the scientific community for hundreds of years: why does the narwhal, or "unicorn," whale have an 8-foot-long tooth emerging from its head, and what is its function? view more (2005-12-14)
Scripps research scientists observe human neurodegenerative disorder in fruit flies
A team of scientists from The Scripps Research Institute, Katholeike Universiteit Leuven, and the University of Antwerp, Belgium, among other institutions, has created a genetically modified fruit fly that mimics key features of Charcot-Marie-Tooth disease, a common neurodegenerative disorder that strikes about one out of every 2,500 people in the... view more...

Neanderthal teeth grew no faster than comparable modern humans
Recent research suggested that ancient Neanderthals might have had an accelerated childhood compared to that of modern humans but that seems flawed. view more (2005-09-20)
Computer program useful tool in dental care
Gunnel H'¤nsel Petersson at Malmö University in Sweden has received an award for her studies of Cariogram, a computer program created in Malmö to assess patients' risk of developing tooth decay, dental caries. The program was constructed in 1997 by Professor Douglas Bratthall at the Faculty of Odontology at Malmö University... view more... (2005-02-25)
Vindictiveness doesn't pay
Vindictiveness doesn't pay. This has been demonstrated by a current study at Bonn and Maastricht Universities. According to this study, a person inclined to deal with inequity on a tit-for-tat basis tends to experience more unemployment than other people. Vindictive people also have less friends and are less satisfied with their lives. The study... view more... (2009-03-27)
Scientists discover why teeth form in a single row
A system of opposing genetic forces determines why mammals develop a single row of teeth, while sharks sport several, according to a study published today in the journal Science. When completely understood, the genetic program described in the study may help guide efforts to re-grow missing teeth and prevent cleft palate, one of the most common... view more... (2009-02-27)
Sea urchin digging teeth are designed to stay sharp
Sea urchins dig themselves hiding holes in the limestone of the ocean floor using teeth that don't go blunt. Weizmann Institute scientists have now revealed their secrets, which might give engineers insights into creating ever-sharp tools or mechanical parts. view more (2009-05-04)
Research simplifies diagnosis of Charcot-Marie-Tooth disease
Hereditary Charcot-Marie-Tooth (CMT) disease strikes 1 in 2500 people. Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to the University of Antwerp are now demonstrating that mutations in mitofusin 2 are the major cause of CMT2, a specific type of the disease. view more (2006-07-25)
Ultra-fast, ultra-intense laser has clean-cut advantage
Many people equate lasers with a sci-fi battle in a galaxy far, far away or, closer to home, with grocery store scanners and compact disc players. view more (2008-03-14)
New cancer weapon: nuclear nanocapsules
Rice University chemists have found a way to package some of nature's most powerful radioactive particles inside DNA-sized tubes of pure carbon -- a method they hope to use to target tiny tumors and even lone leukemia cells. view more (2007-08-24)
Researchers present Phase 2 clinical results for Acologix AC-100
Today, researchers from Acologix (Hayward, CA, USA), the University of California (San Francisco, USA), and the University of Connecticut (Simsbury, USA) will announce the results of a Phase 2 clinical trial of AC-100 (also known as Dentonin), reporting that it met its primary goal of stimulating the formation of new dentin when applied directly... view more...

To keep mouths safe, don't just wear a mouthguard; keep it clean
Fractured teeth, neck injuries and abrasions in the mouth, also known as sports-related dental injuries, are ever present among athletes. According to the U.S. Centers for Disease Control, sports-related dental injuries account for more than 600,000 emergency room visits each year. view more (2007-12-11)
