New candy eats 'bad' bacteria in the mouth, benefitting teeth Dec. 04th 2013
Our mouths are a delicate balance of good and bad bacteria. When we clean our teeth, the aim is to knock out cavity-causing bacteria, while allowing beneficial oral bacteria to thrive. Now, researchers have developed a sugar-free candy, which contains dead bacteria that bind to bad bacteria, potentially reducing cavities.
Protection from periodontitis and related chronic diseases Nov. 12th 2013
A drug currently used to treat intestinal worms could protect people from periodontitis, an advanced gum disease, which untreated can erode the structures - including bone - that hold the teeth in the jaw. The research was published ahead of print in Antimicrobial Agents and Chemotherapy.
Epigenetic effects on cell signaling leads healthy stem cells to create benign fibromas in the jaw Nov. 11th 2013
A new study from the Ostrow School of Dentistry published in Cell Stem Cell illustrates how changes in cell signaling can cause ordinary stem cells in the jaw to start forming benign but potentially harmful tumors.
Bio patch regenerates missing or damaged bone Nov. 08th 2013
Research led by the University of Iowa has tested a "bio patch" that regenerates missing or damaged bone by inserting DNA into nano-sized particles to deliver bone-making genetic instructions directly into cells.The method succeeded in regrowing enough bone to fully cover skull wounds in live rats.
Prescription opioid availability and associated abuse Nov. 07th 2013
Researchers at Indiana University-Purdue University Indianapolis say one way to gauge the extent of prescription opioid pain reliever abuse in any Indiana county is to count the number of health care providers, particularly dentists and pharmacists.
Debunking the 'myths' of global medical tourism Nov. 06th 2013
A team of British researchers is warning governments and health care organizations around the world not to fall for the myths and hype surrounding medical tourism.With the promise of a lucrative market and huge global market opportunities, the appeal of medical tourism is hard to miss.
Atherosclerosis progression and changes in periodontal health Nov. 06th 2013
Taking care of your gums by brushing, flossing, and regular dental visits could help hold heart disease at bay. Researchers at Columbia University's Mailman School of Public Health have shown for the first time that as gum health improves, progression of atherosclerosis slows to a clinically significant degree. Findings appear online in the Journal of the American Heart Association.
Bringing needed immune cells to inflamed tissue to treat gum disease Nov. 06th 2013
The red, swollen and painful gums and bone destruction of periodontal disease could be effectively treated by beckoning the right kind of immune system cells to the inflamed tissues, according to a new animal study conducted by researchers at the University of Pittsburgh.
Improving gum health may reduce heart risk Nov. 04th 2013
Researchers at Columbia University in New York suggest that if you look after your gums, you could also be reducing your risk of heart disease. They claim that improving dental care slows the speed with which plaque builds up in the arteries.
Newly revised guidelines from the American Association of Endodontists may help to save traumatized teeth Nov. 01st 2013
Teeth affected by a traumatic injury can often be saved, and newly revised guidelines from the American Association of Endodontists can help dental professionals quickly determine the best course of action to treat traumatic dental injuries.
Microbial 'signature' discovered in oral bacteria that can discriminate between ethnicities Oct. 25th 2013
The bacteria in the human mouth - particularly those nestled under the gums - are as powerful as a fingerprint at identifying a person's ethnicity, new research shows.Scientists identified a total of almost 400 different species of microbes in the mouths of 100 study participants belonging to four ethnic affiliations: non-Hispanic blacks, whites, Chinese and Latinos.
Poor oral health affects Olympic athletes' performance Oct. 05th 2013
The training regimen for any Olympic athlete is intense, but getting oral health into shape is usually not part of the routine. However, new research examining the impact of 2012 Olympic athletes' oral health may now make the toothbrush as important as athletic shoes.
High-dose statin may reduce gum inflammation Oct. 04th 2013
A new study offers more evidence of a link between oral and heart health. It found that high-dose statins can reduce gum inflammation in heart disease patients in as little as 4 weeks.The researchers report their findings in the latest online issue of the Journal of the American College of Cardiology.Statins are commonly prescribed for lowering blood cholesterol.
In heart disease patients, gum inflammation reduced by high-dose statins Oct. 04th 2013
Statins, commonly prescribed medications for lowering cholesterol, also reduced inflammation associated with gum disease in a new study published in the Journal of the American College of Cardiology. The study suggests that steps taken to reduce gum disease may also reduce inflammation in the arteries and vice versa.
Standards for dental profession put new focus on patients, UK Oct. 01st 2013
New standards for the dental profession came into force on 30 September which put a much stronger focus on patients' expectations and entitlements. Issued by the General Dental Council (GDC), the UK's dental regulator, the standards were developed following intensive consultation with patients and the public.
You can't hide your feelings! Women six times 'more disgusted by dental treatment' than men Sep. 25th 2013
After looking at pictures of dental treatment scenes, researchers discovered that female patients scared of the dentist were six times more likely to be disgusted with what they saw, compared with non-dental phobic women.In a battle of the sexes, dental phobic women struggled to hide their emotions.
Tooth sensor accurately detects oral activity Sep. 22nd 2013
Whether eating, drinking, talking, coughing, breathing or smoking, our mouths are always in use. Because the mouth is an opening that can yield health information for our body, a team from National Taiwan University created a sensor that embeds within a single tooth.The sensor is so small that it can either fit inside an artificial tooth or straddle a real one.
Dental implants from nanodiamonds Sep. 20th 2013
UCLA researchers have discovered that diamonds on a much, much smaller scale than those used in jewelry could be used to promote bone growth and the durability of dental implants.Nanodiamonds, which are created as byproducts of conventional mining and refining operations, are approximately four to five nanometers in diameter and are shaped like tiny soccer balls.
Bacteria responsible for gum disease facilitates development and progression of rheumatoid arthritis Sep. 16th 2013
Does gum disease indicate future joint problems? Although researchers and clinicians have long known about an association between two prevalent chronic inflammatory diseases - periodontal disease and rheumatoid arthritis (RA) - the microbiological mechanisms have remained unclear.
Dental cavities linked to lower risk of head and neck cancer Sep. 13th 2013
According to a surprising new study, people who have more dental cavities are at lower risk of being diagnosed with head and neck cancer, compared with patients who have few or no cavities.Dental cavities (or caries) are caused by tooth decay. This is when the bacteria present in the mouth make lactic acids that strip away minerals in the tooth by fermenting carbohydrates.
