Study: Dental X-rays linked to common brain tumor
The Huffington Post    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Dental X-rays may help dentists collect essential information about oral health, but a new study is raising questions about their safety. The new research links regular dental imaging to one of the most common types of brain tumors and suggests adults who were regularly exposed to X-rays in the past, before dosages were lowered, might have an especially pronounced risk. For the new study, scheduled to be published online in the American Cancer Society's journal Cancer, researchers examined data from more than 1,400 patients who had been diagnosed with meningioma: This is a type of tumor that grows in membranes surrounding the brain and spinal cord and generally is noncancerous, but can lead to headaches, vision and memory problems and loss of speech and motor control. The researchers compared those individuals to more than 1,300 adults who were tumor-free. More



Dental insurance, but no dentists
The New York Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
We know that too many Americans can't afford primary care and end up in the emergency room with asthma or heart failure. But in the debate over healthcare coverage, less attention has been paid to the fact that too many Americans also end up in the emergency room with severe tooth abscesses that keep them from eating or infections that can travel from decayed teeth to the brain and, if untreated, kill. More than 830,000 visits to emergency rooms nationwide in 2009 were for preventable dental problems. More

Mouth bacteria linked to heart inflammation
EmpowHER    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Your oral health is your heart's biggest ally. If you are not careful to keep your mouth clean and healthy, your heart is at risk for inflammation. When there is a lack of care in oral health, causing plaque to build up and attracting more bacteria, bacteria can then enter the bloodstream through bleeding gums caused by periodontal disease. This type of bacteria is called Streptococcus gordonii, and when it ends up in the bloodstream it can evade the immune system by masquerading as a protein and binding with platelets. More

In Kansas, no consensus on how to end 'dental deserts'
KaiserHealth via Gant Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In an ongoing disagreement over how to solve dental care access problems in Kansas, there is one thing no one disputes: the great need. That need was on display in February when the Kansas Dental Charitable Foundation held its 11th free clinic of the past decade. Known as the Kansas Mission of Mercy, the clinic was staffed by volunteer dentists in a vacant Walmart store in Kansas City. More

Study suggests dental therapists 'safe' pulling American teeth
PBS NewsHour    Share    Share on FacebookTwitterShare on LinkedinE-mail article
If you're like most Americans, you probably think getting a tooth filled is about as much fun as undergoing a colonoscopy. But oral health is no less an important part of staying healthy. Untreated dental disease can lead to serious medical conditions and — in extremely rare cases — it can kill you. In spite of that, more and more Americans have been experiencing trouble accessing a dentist in recent years. It's not just the shortage of dentists that's the problem. It's also a reflection of how many people can't afford the cost of care or who lack dental insurance. Also exacerbating the problem is the fact that a lot of dentists won't treat Medicaid patients. Reimbursement rates in the federal-state program are often notoriously low. More

Lithium disilicate FDPs fare well in 10-year study
DrBicuspid.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
All-ceramic materials are firmly entrenched in prosthodontics, but until recently there was a gap in the research documenting their performance. Now a new study in the Journal of the American Dental Association has established that after 10 years, three-unit fixed dental prostheses made from monolithic lithium disilicate have survival rates similar to metal-ceramic FDPs and better rates than other all-ceramic materials.

New Penn dental researcher George Hajishengallis gets at the root of gum disease
Penn News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Trained as a dentist in Greece, George Hajishengallis, one of the newest faculty members at the University of Pennsylvania School of Dental Medicine, was happy enough with the idea of practicing dentistry there. But something was missing. "As important as clinical treatment is — and I think it's more important than research," Hajishengallis said, "it can become routine." Realizing he would miss the stimulus of constant learning, Hajishengallis made the decision to continue his studies in the United States, enrolling in a doctoral program at the University of Alabama at Birmingham.

New tooth-brushing technique, toothpaste offers 4 times more cavity, plaque protection
EmaxHealth    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers from the Sahlgrenska Academy at the University of Gothenburg in Sweden have discovered that by massaging the gums with a high-fluoride toothpaste that the war against cavities and plague-causing gum disease could be over for many people. One of the most proven effective tactics against cavities and plaque formation has been the recommended use of low concentrations of fluoride in drinking water and in toothpastes. However, researchers recently have posed the question of whether the protective abilities of fluoride could be increased by finding an easy way to increase fluoride retention. More

Taking a bite out of life after tooth loss
Queens Chronicle    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The crunch of biting into a ripe apple, the sweet buttery taste of corn on the cob, the chewy goodness of juicy steak — these are all sensations that some older adults can no longer enjoy as the result of tooth loss. Some 27 percent of people over the age of 65 have no remaining teeth, according to the National Institute of Dental and Craniofacial Research. The average person in that age group, however, has about 19 pearly whites left. Older African Americans, smokers, and those with lower incomes and less education tend to have greater tooth loss, according to the NIDCR. More

Mouthing off against oral cancer
PR Newswire via The Sacramento Bee    Share    Share on FacebookTwitterShare on LinkedinE-mail article
According to the Centers for Disease Control and Prevention, more than 30,000 new cases of oral cancer are diagnosed each year, and more than 8,000 deaths occur annually. The five-year survival rate for oral cancers is roughly 50 percent. In observance of Oral Cancer Awareness Month, the Academy of General Dentistry recommends that patients receive a dental exam from a general dentist every six months. Dental exams not only help to decrease a patient's risk of oral diseases, such as cavities and periodontal disease, but they also may help to diagnose other, sometimes life-threatening, medical conditions, such as oral cancer.

Treating gum disease may help diabetics avoid complications
HealthDay News via U.S. News & World Report    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Treating gum disease in people with diabetes reduces their medical costs and hospitalizations, new research shows. The three-year study included diabetes patients with gum (periodontal) disease who were randomly selected either to receive periodontal therapy or no treatment (control group). Those in the treatment group underwent periodontal therapy in the first year and their gum health was maintained for the following two years. The patients in the control group had incomplete periodontal therapy before the study and did not receive regular periodontal maintenance during the study. More

Incisive research links teeth with diet
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
You are what you eat is truism that has been given new impetus by "cutting edge" research led by the University of Leicester that reveals your teeth literally are shaped by your food. Indeed, evidence from teeth can be used to determine what has been eaten by an animal providing a new way of working out the diets of wild animals that doesn't involve the unpleasant task of looking at the contents of their guts. Scientists say it is also possible to use these methods to investigate diets of extinct animals such as giant marine reptiles and dinosaurs. More

With flossing, it's good to start with baby steps
Postmedia News via National Post    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Although she believes her first visit to the dentist was at age 5, Ericka Behar is part of a generation of Canadians that didn't grow up including flossing as a regular part of dental maintenance. "I have fillings in my mouth," says the Port Moody, British Columbia, mother of two. "I don't want my children to go through that." To help ensure they don't get cavities, Behar has made flossing mandatory for her children, a 6-year-old boy and a 2-and-a-half-year-old girl. "They have great checkups," Behar says. "Flossing is part of their whole routine. When we go to the dentist and the hygienist brings out the floss, they know what it is and what it's for." More
