Scientists looking into stem cell teeth
KGO-TV    Share   Share on FacebookTwitterShare on LinkedinE-mail article
For centuries, adult tooth loss has been handled by dentures and, more recently, dental implants. Now, researchers at the University of California-San Francisco are working on a technique that someday might make replacement teeth a reality. When Dr. Ophir Klein looks at the badly deformed teeth in some patient photos, he dreams of someday being able to replace them — not with artificial dentures, but real teeth created in a lab. "In the long run you could, for example, take the precursor organ itself that was not fully developed and implant into the jaw and allow it to develop there," Klein said. To make that kind of advance a reality, Klein's team is working to unlock the secrets of how stem cells form into teeth. Using mouse models, they're studying epithelial cells that differentiate to become hardened tooth enamel. More

A beautiful, healthy smile's important for overall health
KNXV-TV    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Aspen Dental dentist Dr. Brandon Arnow said there are a number of studies indicating that your oral health impacts your overall health. For example, gum disease has been linked with the incidence of common health issues such as heart disease, diabetes and stroke. And new research is coming out all the time. Recently, researchers at New York University found the first long-term evidence that gum disease may increase the risk of cognitive dysfunction associated with Alzheimer's disease in healthy individuals as well as in those who already are cognitively impaired. So, it's incredibly important for people to maintain their oral health. Unfortunately, people neglect their oral health for a variety of reasons: anxiety, fear, embarrassment. More

Why brush twice a day?
Dental Economics    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Why brush twice a day? There are several answers to this question. We brush, floss and rinse repeatedly every day to reduce the bacterial load in the mouth, prevent disease development, avoid halitosis, remove stains and remove food particles, among others. All these answers are true, valid and accurate, but they do not drill down to the bottom line, bare bones, one ultimate reason. More

Things to know about full mouth reconstruction
Dental Health Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
When hearing about full mouth reconstruction, many people simply get terrified. However, it only sounds extremely complicated and laborious. So what does full mouth reconstruction imply then? It is actually a series of consecutive cosmetic dentistry interventions, which will help correct teeth alignment, the shape of the gums and in general the whole mouth surface. Generally, dentists or cosmetic dental surgeons who are going to treat the patient should explain in detail every procedure. Thus, if the patient knows and understands what is about to happen, and how these functions are going to be changed and restored, he/she is willing to accept more open heartedly and bravely the operations.

Dr. Irwin D. Mandel, expert on dental chemistry, dies at 89
The New York Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Millions of dental patients who have successfully avoided unpleasant drill-and-fill procedures owe much to Dr. Irwin D. Mandel, an expert on dental chemistry jocularly known among colleagues as a leader of "the Salivation Army." Mandel, a founder of the preventive dentistry movement who did research into the biochemistry of saliva that has had significant impact in medical fields beyond his own, died May 26 in Montclair, N.J., his daughter Carol Ann Mandel said. He was 89 and lived in West Caldwell, N.J. Mandel was the founding director of the division of preventive dentistry at the Columbia University College of Dental Medicine, the first such department in the country. The division's mission was to promote practices that since have become standard. More

New reasons to brush and floss
The Huffington Post    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Taking good care of your teeth at every stage of life is a good way to avoid painful toothaches, expensive trips to the dentist and tooth loss in old age. But there is another powerful reason to practice good oral health: It can affect the health of your whole body. Research shows that the bacteria that cause tooth decay and gum disease in your mouth may also play a role in heart disease and stroke. And there is some evidence that tooth loss before age 35 may be a risk factor for Alzheimer's disease. More

Researcher: Association between biomarkers, disease often overstated
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
More than two dozen widely cited studies linking genes or other "biomarkers" to specific diseases vastly overstate the association, according to new research from an expert in scientific study design at the Stanford University School of Medicine. As a result, clinicians may be making decisions for their patients based on inaccurate conclusions not supported by other, larger studies. The widely cited studies include one linking the BRCA1 mutation with colon cancer, another that links levels of C-reactive protein in the blood with cardiovascular disease and one that links homocysteine levels with vascular disease. The exaggeration is likely the result of statistical vagaries coupled with human nature and the competitive nature of scientific publication, said John Ioannidis, M.D., D.Sc., chief of the Stanford Prevention Research Center, in a paper to be published in the June 1 issue of the Journal of the American Medical Association.

Natural, safe anti-inflammatory medicines
Fox News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An estimated 50 million Americans suffer from chronic pain, according to the American Pain Foundation. That's a lot of pain. And that adds up to a lot of drug use, notably the category called NSAIDs, or non-steroidal anti-inflammatory drugs. Ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), diclofenac (Voltaren) and Celebrex belong to this class of drugs. These drugs are designed to inhibit activity of what is known as the COX2 enzyme, a major factor in pain. This natural enzyme is created in all of us, and is responsible for the production of some of the agents called prostaglandins, which trigger pain and inflammation. The role of inflammation in pain is pretty straightforward. Any of a variety of insults can cause inflammation in the tissues of our bodies. External insults like burns, bites, scrapes, stings, cuts and bruises cause skin tissue to swell as protective fluids pour into damaged tissue between cells. Nerves also may be directly hurt. All of this activity is accompanied by pain. More
