OHSU School of Dentistry finds some orthodontic appliances are more prone to bacteria
Researchers at the Oregon Health & Science University School of Dentistry (www.ohsu.edu/sod) have found the majority of patients with self-ligating orthodontic brackets retain fewer bacteria in plaque than patients with elastomeric orthodontic brackets. view more (2009-04-15)
Exposure to alkaline substances can result in damaged teeth
It has long been known that acids can erode tooth enamel but a new Swedish study from the Sahlgrenska Academy at the University of Gothenburg shows that strong alkaline substances can damage teeth too - substances with high pH values can destroy parts of the organic content of the tooth, leaving the enamel more vulnerable. view more (2009-10-28)
Nanotechnology may increase longevity of dental fillings
Tooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade. view more (2009-07-02)
Why do rodents' teeth stay sharp? What is the difference between the mouse and the kangaroo?
Answers to these two questions are given by two recent studies on tooth development and evolution. Scientists at the University of Helsinki have identified the gene responsible for tooth enamel formation, which also explains the sharp incisors of rodents. The second study adds to our knowledge on evolution: the differences between teeth in various... view more... (2004-11-10)
Protein-coated dental implants could improve bone regeneration
Titanium dental implants coated with proteins that induce bone formation may be a key advancement in treating tooth loss due to gum disease, researchers say. view more (2006-07-18)

In the January 1st issue of G&D, Drs. Thomas Mullen and William Marzluff (UNC Chapel Hill) lend new insight into the degradation of mammalian histone mRNA. view more (2008-01-02)
Researchers move closer to switching nuclear isomer decay on and off
Livermore researchers have moved one step closer to being able to turn on and off the decay of a nuclear isomer. view more (2007-04-06)
Studies evaluate health effects of dental amalgam in children
Scientists supported by the National Institute of Dental and Craniofacial Research (NIDCR), part of the National Institutes of Health, report in this week's Journal of the American Medical Association the results of the first-ever randomized clinical trials to evaluate the safety of placing amalgam fillings, which contain mercury, in the teeth of... view more...

Antibiotics do not prevent recurrent myocardial infarcts in subjects with periodontitis
Periodontitis, an infection of the gingiva and tooth-supporting tissues, may influence the effectiveness of antibiotics used for the prevention of recurrent cardiovascular events. view more (2006-01-05)
EARLY ASSESSMENT PREDICTS LONG-TERM EFFICACY OF HIV-1 ANTIRETROVIRAL THERAPY (p 1760)
A study in this week's issue of THE LANCET highlights how very early (one week) assessment can reliably predict the long-term effectiveness of antiretroviral therapy for HIV-1. Early assessment of antiretroviral drug efficacy is important for the prevention of the emergence of drug-resistant virus and unnecessary exposure to ineffective and toxic... view more...

Warning for Teens: Teeth and Jewelry Don't Mix
TAU study finds that oral tissue piercings fracture teeth and increase dental complications in early adulthood view more (2008-06-23)
Overweight kids have fewer cavities, new study shows
Contrary to conventional wisdom, overweight children have fewer cavities and healthier teeth compared to their normal weight peers, according to a study published in this month's issue of Community Dentistry & Oral Epidemiology. view more (2008-04-02)
NYU dental researchers find link between C-section delivery and higher risk of cavities in newborns
A new study by NYU dental researchers suggests that women with dental caries (cavities) who deliver Caesarean-section babies should pay special attention to their newborns' oral health. view more (2005-08-24)
Great white's mighty bite revealed
Using sophisticated computer modelling techniques they have also calculated that the bite force of the great white's extinct relative, the gigantic fossil species Carcharodon megalodon (also known as Big Tooth) is the highest of all time, making it arguably the most formidable carnivore ever to have existed. view more (2008-08-04)
Grow Your Own Teeth
People who have lost or damaged teeth could soon be growing their own, thanks to a major scientific breakthrough by a start-up, Odontis Ltd, formed by King's College, London. An investment of £400,000 from NESTA (the National Endowment for Science, Technology and the Arts) - the organisation that nurtures UK creativity and innovation and the... view more... (2004-04-30)
Abertay scientist is in demand for wooden ships
Dr Derek Sinclair, scientist in the University's Scottish Institute for Wood Technology (SIWT), flies to Sweden next week to speak at a conference on preserving the Vasa - a massive 16th-century wooden warship which was recovered from the seabed off Stockholm in 1961. view more (1999-02-12)
Tetracycline plus teeth equal gray smile
Many adults over age 35 cover their mouth to avoid smiling in public in order to hide their teeth darkened by tetracycline stains.
