Researchers: Invasive dentistry may raise short-term heart, stroke risk
HealthDay News via U.S. News & World Reports    Share   Share on FacebookTwitterShare on LinkedinE-mail article
Invasive dental procedures designed to treat gum inflammation may raise the risk for heart attack and stroke, researchers say. But the increase appears to be slight and short-term, the study team noted. "I don't want to downplay this entirely because we saw a genuine rise in cardiovascular risk in the period just after dental work was done among patients undergoing invasive treatment," said study co-author Liam Smeeth, a professor of clinical epidemiology at the London School of Hygiene and Tropical Medicine in England. "But the overall risk is quite small and endures for only a very brief period." More


Researchers: Osteoporosis drug regrows jaw bone
Reuters    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Eli Lilly and Co's osteoporosis drug Forteo can regrow bone in jaws damaged by severe bone-destroying conditions called osteonecrosis and periodontitis, doctors reported. The research, presented at the annual meeting of the American Society for Bone and Mineral Research in Toronto, suggests that the drug may spur growth in a damaged jaw, the researchers said. Forteo, known generically as teriparatide, cuts in half the risk of bone fractures in patients with thinning bones by stimulating the growth of new bone. But it is seldom given for more than two years out of fear that long-term exposure might lead to osteosarcoma, a type of bone cancer. More

OHSU School of Dentistry examines antimicrobial drug interactions in periodontology
OHSU    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers at the Oregon Health & Science University School of Dentistry have found that a light-detecting biosensor system can quickly and effectively determine whether antibacterial treatments are working in patients with periodontitis. The OHSU team also found that the anesthetics lidocaine and prilocaine, and the antiseptic chlorhexidine do not interfere with the antibiotic minocycline hydrochloride when it is used to treat periodontal disease, and that the drugs can actually complement the antimicrobial activity of such treatment.

Canada declares BPA toxic, sets stage for more bans
Reuters    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Canada has declared bisphenol A a toxic chemical, prompting calls for far-reaching curbs on the industrial chemical that is used in everything from the linings of aluminum cans to coatings on electronic till receipts. Canada added the compound, known as BPA, to a list of substances deemed potentially harmful to health or the environment in a notice published Oct. 13 in the Canada Gazette. That makes it easier for Ottawa to regulate the use of the chemical, perhaps by limiting how much BPA can be released into air or water or perhaps with outright bans on its use in specific food containers.

Loss of dental hygiene program leaves cavity in AASU's curriculum
The Inkwell    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Armstrong Atlantic State University in Savannah, Ga., began its Department of Dental Hygiene in 1968, and it was the first of its kind in the state. Amid the onslaught of statewide education budget cuts announced this spring, AASU's administration made the decision to cut the 42-year-old program. "It's really sad that they are closing a facility that holds the oldest program in the state," said Janice Mengel, assistant professor of dental hygiene at AASU. The two-year program currently has approximately 40 students and provides dental services for a large portion of the local community. Suzanne Edenfield, head of the dental hygiene program, said that the office receives at least 100 calls a week from patients seeking dental care at the student clinic. More

Mass High Tech Business News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Forsyth Institute, a dental research and teaching organization, has landed a four-year $20.7 million grant from the National Institute of Dental and Craniofacial Research to apply to three research projects aimed at the understanding and treatment of periodontal disease. Also known as gum disease, periodontal disease affects 40 percent of U.S. adults, Forsyth officials reported, and the disease has been linked to diabetes, metabolic syndrome, cardiovascular disease, some cancers and preterm birth. The three grant-funded projects are expected to address how and why the disease develops and progresses, as well as disease prediction methods and potential treatment of the disease. More


USC researchers investigate HIV shedding in saliva
USC News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Research led by the Ostrow School of Dentistry at the University of Southern California has documented the important relationship between oral and overall health and the likelihood of passing HIV through saliva. As part of the multi-center, National Institutes of Health-funded Women's Interagency HIV study, professor Mahvash Navazesh and her colleagues from the Keck School of Medicine of USC and the University of Illinois at Chicago examined hundreds of HIV-positive women. Blood and saliva samples taken at six-month intervals throughout five and a half years were tested to determine the amounts of HIV and CD4 immune cells present in each. More

Bone infection picked up at dentist almost cost girl, 6, her arm
The Daily Record    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A 6-year-old girl went into hospital to have two teeth out and nearly lost her arm. Cameron McGlashan fell victim to a bone infection after dentists cut into her gum. She started to complain that her elbow was sore, but her mother, Julia, thought at first that she had hurt it falling off her bike. And it took three trips to accident and emergency, blood tests, scans and a week in hospital before a sharp-eyed doctor spotted an abscess on the elbow caused by osteomyelitis. By that time, the bone was disintegrating and Cameron needed a three-hour op to save the arm. More

Fluoridation debate nowhere near resolution    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In 1945, Grand Rapids, Mich., became the first city in the U.S. to fluoridate its community water. Now, some 72 percent of the U.S. population — 196 million people — is on fluoridated public water systems, according to the latest data from the Centers for Disease Control and Prevention, released last month. In fact, the CDC considers water fluoridation one of the greatest public health achievements in the 20th century. Yet controversy continues regarding the long-term health effects — and potential risks — of fluoride consumption. (May require free registration to view article.) More

Study: HPV linked to oral cancer
AFP via Google News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Mouth and throat cancer could be caused by the virus that causes genital warts and cervical cancer, and it could be spreading through sex and French-kissing, according to a recently published study. "In addition to the known oral cancer risk factors — smoking, drinking alcohol and chewing betel nuts — human papillomavirus has been added to the list," the study published in the Centers for Disease Control and Prevention's Emerging Infectious Diseases report says. HPV has been documented in many cases of oropharyngeal squamous cell cancer, which is on the rise. More

Dental implant placements grew more than 10 percent across BRIC countries in 2009 despite economic crisis
PR Newswire    Share    Share on FacebookTwitterShare on LinkedinE-mail article
According to Millennium Research Group, in 2009 approximately 1.6 million dental implants were placed in the BRIC (Brazil, Russia, India and China) countries, and this number will expand at a double-digit rate during the next five years. Despite the global economic crisis, procedure volumes grew more than 10 percent across the BRIC countries in 2009. The emerging nature of the BRIC countries' economies has allowed them to largely resist the negative effects on dental implant placement volumes that many of the developed markets experienced; what little effects have been felt will be quickly resolved, with growth rates returning to pre-recession figures in the next five years.

Tuatara acts as model for false teeth damage
Laboratory News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An iconic reptile native to New Zealand has been used as the basis for a 3-D computer model investigating how damage to teeth is prevented by the jaw, muscles and brain in the absence of the periodontal ligament. The research, funded by the Biotechnology and Biological Science Research Council, used the tuatara, a lizard-like reptile whose teeth are fused into the jaw bone, much like dental implants. The 3-D computer model was used to investigate the feedback between the jaw joints and muscles in a creature that lacks periodontal ligaments, and to understand how the animal knows how hard to bite.
