Perfect Looking Teeth

A new measuring technique determines the effect of dental care products and helps  them so they polish the rough tooth surfaces until they are perfectly smooth, while preserving the tooth enamel. The tooth surface wears down and gets uneven – and the problem is that dental plaque adheres particularly well to a rough surface. Dentists therefore offer professional cleaning services, removing plaque and discoloration with abrasive prophylactic pastes. This renders the tooth surface beautifully smooth, making it difficult for bacteria to gain a foothold. Yet there is a risk that the polishing treatment will also grind away precious tooth enamel and dentin at the exposed necks of teeth. The manufacturers therefore have to find the happy medium when developing their prophylactic pastes: The pastes should be just abrasive enough to remove superficial discoloration and plaque, but preferably not wear down the tooth enamel. Until now, scientists lacked any realistic objective measuring techniques to assess tooth abrasion caused by chewing and by the effect of toothpastes. A leading manufacturer of dental hygiene products asked the Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, one of whose specialties is the analysis and visualization of surface roughness, to help them develop new […]

Family Doctor’s Not Happy and How to Boost your Immune System

I found two great articles. The first deals with how (primary-care) family doctors are not happy with the current bussiness in the U.S.  According to a recent survery “49 percent [of family doctors] said they’d consider leaving medicine. Many said they are overwhelmed with their practices, not because they have too many patients, but because there’s too much red tape generated from insurance companies and government agencies.” There is expected to be a shortage in the tens of thousands within the next 15-20 years. In addition current medical students are not interested in pimary care and want to enter other alternatives. To read the entire article visit http://www.cnn.com/2008/HEALTH/11/17/primary.care.doctors.study/index.html A current practicing primary care physician named James Hubbard has cited “anxiety and hassel” as the reasons he is currently part time. He publishes his own magazine called Family Doctor Mag. On his website ELIZABETH A. PECTOR, M.D., a family physician has written an excellent article on how to boost your immunity system this upcoming winter. The key take aways from the article include eating well, avoiding second hand smoke, regular exercise, lack of stress, and vaccinations. I feel that vaccinations should be taken with a cautious approach as I have watched […]

Teeth and Jewlery Do Not Mix

Researchers from Tel Aviv University have found good reasons to think twice about piercing one’s tongue or lip. Dr. Liran Levin, a dentist from the Department of Oral Rehabilitation, School of Dental Medicine at Tel Aviv University has found that about 15 to 20 percent of teens with oral piercings are at high risk for both tooth fractures and gum disease. Resulting tooth fractures as well as periodontal problems, he says, can lead to anterior (front) tooth loss later in life. High rates of fractures due to piercings are not found in other age groups, and cases of severe periodontal damage in teens without oral piercings are similarly rare, says Dr. Levin, who conducted the study with partners Dr. Yehuda Zadik and Dr. Tal Becker, both dentists in the Israeli Army. Their initial study was done on 400 young adults aged 18-19, and the results were published in the well-known peer-reviewed journal Dental Traumatology in 2005. A new review by Drs. Levin and Zadik published in the American Dental Journal in late 2007 is the first and largest of its kind to document the risks and complications of oral piercings, drawing on new research. Ten percent of all New York […]

Gene Linked to Increased Heart Disease in Migraine Women

Heart disease is the leading cause of death and stroke is the third leading cause of death in the United States. Women who experience migraine with aura appear to be at an increased risk of heart disease and stroke if they have a certain gene. For the study, researchers followed 25,001 Caucasian women for the occurrence of cardiovascular disease, including heart attacks and ischemic stroke. About 18 percent of the women in the study had a history of migraine while 40 percent of those with active migraine reported migraine with aura. Migraine with aura can be described as neurological symptoms that usually last for about 30 minutes and most often lead to visual disturbances. The women were also tested for a certain gene variant in the methyleneterahydrofolate reductase gene. During a 12-year follow-up period, 625 cardiovascular disease events occurred. The study found that women who had both the gene variant and migraine with aura had more than three times the risk of cardiovascular disease, which was driven by four times the risk for stroke compared with women who did not have the gene variant and no history of migraine. “This gene by itself does not appear to increase the risk […]

Xylitol Gummy Bears

The tooth protecting sugar substitute xylitol has been incorporated into gummy bears to produce a sweet snack that may prevent dental problems. Giving children four of the xylitol bears three times a day during school hours results in a decrease in the plaque bacteria that cause tooth decay. Xylitol is a naturally occurring sugar alcohol that is frequently used as a sweetener. It has been shown to reduce levels of the harmful mutans streptococci bacteria  known to cause tooth decay. Xylitol chewing gums are  not considered to be suitable for younger children. A recent study demonstrates that six weeks of xylitol gummy bear snacking, the levels of harmful MS bacteria in the children’s plaque was significantly reduced. However, I have seen studies and reports that dogs die from ingesting a small amount of xylitol. Thus I do not think that these xylitol gummy bears will be effective. If you have a dog, you probably should not purchase products with xylitol especially if you have children.
