Study: Toothpaste chemical impairs muscle function
Triclosan, an antibacterial chemical commonly used in toothpaste, mouthwash, hand soaps, and other personal care products, has been found to hinder muscle contractions at a cellular level, according to a new study in the Proceedings of the National Academy of Sciences. Researchers from the University of California at Davis and the University of Colorado performed several experiments to evaluate the effects of triclosan on muscle activity, using doses similar to those that people and animals may be exposed to every day.

Blood type may affect heart disease risk
Medical News Today
A person's blood type may affect their risk for heart disease, according to a new study that finds people with blood type A, B or AB were more likely to develop the disease than those with type O. However, the researchers said following a healthy lifestyle can still make a difference to protect people with the higher risk blood types. The senior author of the study is Lu Qi, an assistant professor in the Department of Nutrition at the Harvard School of Public Health in Boston. He and his colleagues report their findings in a paper published online in Arteriosclerosis, Thrombosis and Vascular Biology, one of the American Heart Association journals.More

Michigan licensing board rules for dentist in complaint about sedation
Detroit Free Press
Michigan healthcare regulators did not substantiate allegations that a Troy pediatric dentist over-sedated a 6-year-old Royal Oak boy and sent him home unresponsive. Rebekah Adler, the mother who filed the case against Dr. Jian-Fu Zhu, got a letter with the decision from the allegations section of the Michigan Department of Licensing & Regulatory Affairs. The letter said "violations could not be established," Adler said. The file will be closed, but the records in the case will be saved for five years before being destroyed, the letter said. Zhu's Roseville attorney, Linda Farnen, called the state's action "a vindication of his treatment."More

PR Newswire via The Sacramento Bee
Despite financial woes, Americans are smiling — and when they smile, they want their teeth looking as bright and white as possible. However, consumers don't seem to be interested in costly professional whitening options. According to new research from Mintel, only 10 percent of those looking for brighter smiles took a seat in the dreaded dentist chair for a professional whitening service. Slightly more than 41 percent have tried to whiten their teeth in the last 12 months using toothpaste, while 17 percent have given it a whirl with at-home mouthwash and 15 percent with OTC whitening strips.More

Put some teeth into the Affordable Care Act
Post Bulletin
Jeff Hansel writes, "The Patient Protection and Affordable Care Act has no teeth. No, I don't mean it lacks sound building blocks for improved public health. Rather, the act doesn't put enough focus on dental health. I surely don't want to start health reform all over again, but I think dental health is important enough for both children and adults that it ought to get attention. Most reasonable people will agree suffering is something we would prefer not to experience. And most will agree tooth pain is awful." More

Reading Eagle
Q: U.S. Olympic swimmer Ryan Lochte made a dental fashion statement by wearing diamond-encrusted grill in his mouth after winning a gold medal. I read he had the grill designed to look like the American flag, using diamonds and precious metals. It was reported a Houston jeweler, Johnny Dang, made the grill at a cost of $25,000. How is the grill made to fit over the teeth and stay in place without damaging the teeth? Is it possible to make it out of less expensive material and lower the cost?More

Gingival recession and periodontal therapy
At the heart of a successful dental practice is an educated, proactive hygienist, dedicated to providing more than a "cleaning and checkup." A more personalized level of care builds an ongoing, trusting relationship with patients while maximizing the potential for growth of the practice and patient retention. Many patients remain with their current dentist because of a good rapport with their hygienist.More

Study: Dental health linked to dementia risk
People who keep their teeth and gums healthy with regular brushing may have a lower risk of developing dementia later in life, according to a U.S. study. Researchers at the University of California who followed nearly 5,500 elderly people over an 18-year-period found that those who reported brushing their teeth less than once a day were up to 65 percent more likely to develop dementia than those who brushed daily.More
