A new report assessing the economic viability of services provided by practicing midlevel dental providers in the U.S. shows that they are expanding preventive dental care to people who need it most: children and those who can't afford care. At the same time, they are providing that care at a reduced cost to the dental practice...

Alligators may help scientists learn how to stimulate tooth regeneration in people, according to new research led by the Keck School of Medicine of USC. For the first time, a global team of researchers led by USC pathology Professor Cheng-Ming Chuong, M.D., Ph.D., has uncovered unique cellular and molecular mechanisms behind tooth renewal in American alligators...

Word on the street has it you should replace your toothbrush after suffering from a cold, the flu or a bout of strep throat. That may not be necessary - at least when it comes to sore throats, according to a study presented at the Pediatric Academic Societies (PAS) annual meeting in Washington, DC...

In an advance toward solving a 50-year-old mystery, scientists are reporting new evidence on how the fluoride in drinking water, toothpastes, mouth rinses and other oral-care products prevents tooth decay. Their report appears in the ACS journal Langumir...

Clinical trials continue. Data presented to oral medicine conference Cleaning your mouth and cleaning your arteries could be as simple as a once-a-day oral rinse if additional studies confirm preliminary findings about a new product...

Researchers from Tufts University School of Dental Medicine have discovered a statistical association between the injection of local dental anesthesia given to children ages two to six and evidence of missing lower wisdom teeth...

Researchers at Tufts University School of Dental Medicine and the Forsyth Institute published a study that found that a significant proportion of dental bib clips harbored bacteria from the patient, dental clinician and the environment even after the clips had undergone standard disinfection procedures in a hygiene clinic...

A common test used to determine mercury exposure from dental amalgam fillings may significantly overestimate the amount of the toxic metal released from fillings, according to University of Michigan researchers. Scientists agree that dental amalgam fillings slowly release mercury vapor into the mouth...

Microbes from the human mouth are telling Oak Ridge National Laboratory scientists something about periodontitis and more after they cracked the genetic code of bacteria linked to the condition...

Mouse model studies show that administered genetically or topically, protein Smad7 protects against or heals mouth sores commonly associated with cancer treatment. In some cancer patients treated with radiation, the mouth sores known as oral mucositis become so severe that feeding tubes are required for nutrition and narcotics are needed for pain...

A new study conducted by researchers at the University of North Carolina at Chapel Hill and the University of Adelaide, Australia, has produced the strongest evidence yet that fluoride in drinking water provides dental health benefits to adults, even those who had not received fluoridated drinking water as children...

Scientists have developed a new method of replacing missing teeth with a bioengineered material generated from a person's own gum cells. Current implant-based methods of whole tooth replacement fail to reproduce a natural root structure and as a consequence of the friction from eating and other jaw movement, loss of jaw bone can occur around the implant...

The day a new "biotooth" can be grown in the gap left by a missing tooth as an alternative to having a false one implanted came a step closer recently when UK researchers revealed how they have developed a way to bioengineer new teeth from a person's own gum cells...

Poor dental health, especially tooth loss, is associated with several established cardiovascular risk factors, including diabetes, smoking, blood pressure, obesity and other novel risk factors, according to research being presented at the American College of Cardiology's 62nd Annual Scientific Session...

Postmenopausal women who have smoked are at much higher risk of losing their teeth than women who never smoked, according to a new study published and featured on the cover of the Journal of the American Dental Association by researchers at the University at Buffalo...

New research published in the January/February 2013 issue of General Dentistry, the peer-reviewed clinical journal of the Academy of General Dentistry (AGD), indicates that the use of a germ-killing mouthrinse in addition to regular toothbrushing can significantly reduce plaque and gingivitis, more so than brushing alone...

Among the topics Princeton University researchers discussed during the 2013 AAAS annual meeting: A Higgs boson for cancer? Physics of cancer: The impact of heterogeneity Robert Austin, Professor of Physics Despite incredible advances in our understanding of biology and millions of research dollars spent, cancer remains a leading cause of death worldwide...

A study of the evolution of our teeth over the last 7,500 years shows that humans today have less diverse oral bacteria than historic populations, which scientists believe have contributed to chronic oral diseases in post-industrial lifestyles...
