Fewer heart patients need antibiotics before dental procedures

Based on a review of new and existing scientific evidence, most dental patients with heart disease do not need antibiotics before dental procedures to prevent infective endocarditis (IE), a rare, but life-threatening heart infection.

Secondhand smoke proves to be no 'joke' on oral health

A study published in this monthâs issue of the Journal of Periodontology found that subjects with periodontitis who were exposed to secondhand smoke were more likely to develop bone loss, the number one cause of tooth loss.

Bacteria from patient's dental plaque causes ventilator-associated pneumonia

Patients admitted to a hospital's intensive care unit (ICU) already are seriously ill, so the last thing they need is a new infection. Unfortunately, statistics show that as many as 25 percent of all patients admitted to the ICU and placed on ventilators develop pneumonia, which can be fatal.

Root Beer May Be "Safest" Soft Drink for Teeth

Exposing teeth to soft drinks, even for a short period of time, causes dental erosionâand prolonged exposure can lead to significant enamel loss. Root beer products, however, are non-carbonated and do not contain the acids that harm teeth, according to a study in the March/April 2007 issue of General Dentistry, the AGDâs clinical, peer-reviewed journal. That might be something to consider during the next visit to the grocery store.

Xylitol reduces risk of cavities

The sugar substitute xylitol affects the bacterial composition of the oral cavity even in low doses. On the other hand, a relatively high intake is needed to counteract the production of acid between the teeth, according to Pernilla Lif Holgerson in the dissertation she will defend at Umeå University in Sweden on February 23.

Researchers Use Stem Cells to Regenerate Parts of Teeth

A multi-national research team headed by USC School of Dentistry researcher Songtao Shi, DDS, PhD, has successfully regenerated tooth root and supporting periodontal ligaments to restore tooth function in a swine (an animal) model. The breakthrough holds significant promise for clinical application in human patients. The study appears December 20 in the inaugural issue of PLoS ONE.

Red wine components modulate tissue damage in gums

Researchers are finding that components found in red wine can help in preventing and treating inflammatory periodontal diseases. Periodontitis is a progressive infectious disease affecting the gums and bone that surround and support teeth, often causing tooth movement and leading to permanent tooth loss. About 15% of adults between 21 and 50 years of age and 65% of adults over 50 are affected by this disease.

Photodynamic therapy may be an effective treatment for fungal infections and certain bacterial infections of the oral cavity, including some that are resistant to antibiotics, research from the University at Buffalo's School of Dental Medicine has shown.

Resolvin E1 protects against inflammation and bone loss

Gum disease is initiated by bacteria populating dental plaque and may eventually result in tissue and tooth loss. Gum disease is similar to other chronic inflammatory diseases such as arthritis, where inflammation causes tissue damage and is responsible for the disease. To date, the prevention of gum disease is limited to successful oral hygiene and regular professional care. However, despite these preventive actions, plaque control is not enough to prevent disease in susceptible individuals with a high inflammatory response.

Dentists in research network do not discriminate

Regardless of race, private practice dentists do not discriminate in services they provide their patients, according to a new study from Case Western Reserve University's School of Dental Medicine.

Oral and cardiovascular health are related - Study

New research is reinforcing the longstanding belief that a connection exists between periodontal disease, or severe gum inflammation, and cardiovascular disease. But according to Moise Desvarieux, MD, PhD, infectious disease epidemiologist in the Department of Epidemiology at Columbia University's Mailman School of Public Health, the nature of the relationship is still unclear and patients cannot rely only on good oral hygiene as a way to reduce their risk for heart disease--they must manage other risk factors for the disease as well.

NHANES III Study - Obesity is a significant predictor of periodontal disease

People have a new reason to stick to their New Year's resolution to lose excess weight besides fitting into the latest fashion trends. Researchers from University at Buffalo found that obesity is a significant predictor for periodontal disease, independent of age, gender, race, ethnicity, and smoking. Furthermore, analysis of this national sample suggests that insulin resistance mediates the relationship between obesity and periodontal disease. It was found that the severity of periodontal attachment loss increased proportionally with increasing insulin resistance. In addition, the number of teeth lost increased significantly with increasing levels of insulin resistance. Individuals in the highest insulin resistance category lost 1.1 more teeth compared to individuals in the lowest category.

Licorice compounds may help fight tooth decay

Compounds isolated from licorice root may help prevent cavities, according to researchers at the University of California, Los Angeles. In test tube studies, the scientists showed that an extract from a plant root that is used to make licorice candy and other products contains at least two compounds that appear to be potent inhibitors of Streptococcus mutans, a major cause of dental caries. Their study is scheduled to appear in the Feb. 24 print version of the Journal of Natural Products, a monthly peer-reviewed joint publication of the American Chemical Society and the American Society of Pharmacognosy.

Removing gaps depends on overall health

Dental implants, an artificial tooth root surgically anchored into a jaw to hold a replacement tooth or several teeth in place, offer a permanent solution to replace lost or extracted teeth. Implants have become a treatment of choice for some patients to eliminate the need for removable partial or complete dentures. Other patients choose implants for esthetic purposes or to conserve tooth structure in an otherwise cavity-free mouth.

The Journal of Dental Research has just published the results of a study showing that treatment of gum disease may reduce the risk of cardiovascular disease. Researchers from Australia (Sydney Dental Hospital and Royal North Shore Hospital) and Norway (University of Oslo) collaborated in the PERICAR clinical trial, providing strong evidence linking periodontal (gum) disease to an increased risk of developing blood clots, which could lead to the onset of heart attack and stroke.

New Link Between Severe Periodontitis and Cardiovascular Disease

Virginia Commonwealth University researchers have found that changes in the plasma lipoprotein profile of patients with severe periodontitis a condition characterized by chronic infection and inflammation of the gums - may contribute to these patients elevated risk for heart disease and stroke.

Cranberry juice acts like Teflon for teeth

A team led by oral biologist Hyun (Michel) Koo, D.D.S., Ph.D., at the University of Rochester Medical Center has discovered that the same traits that make cranberry juice a powerful weapon against bladder infections also hold promise for protecting teeth against cavities. Koo found that cranberry juice acts like Teflon® for teeth, making it difficult for the bacteria that causes cavities to cling to tooth surfaces. Stickiness is everything for the microbe Streptococcus mutans, which creates most cavities by eating sugars and then excreting acids that cause dental decay.

Sunlight help prevent periodontal disease

As the days get shorter and colder, it gets harder to spend time in the sun, and that's probably bad for your teeth. According to an article in the Journal of Periodontology from a researcher at Washington University School of Medicine in St. Louis, our teeth may be light-sensitive, at least indirectly.

University of Michigan researchers are testing a new procedure in which they can take a tiny piece of a person's mouth lining, grow it into a dollar-bill sized piece of tissue and graft that expanded piece into the donor's mouth to heal a wound.

Dr. Stephen Feinberg is leading a team that is currently working with five patients to treat small mouth wounds with the grafts. These five patients are part of what is called a proof of concept study for the Food and Drug Administration.

Study will provide basis for targeted therapies for leading cause of adult tooth loss

Scientists at Columbia University Medical Center (CUMC) are looking into the genetic reasons why individuals experience periodontal disease so differently, and why some respond to treatment more successfully than others. Even with treatment, some patients continue to see deterioration of gum condition and eventual loss of teeth.

The research is part of an effort at CUMC to eradicate periodontitis in these patients and better understand how the gum disease develops, and will allow the development of pharmacologic therapies targeted specifically to a person's own genetic predisposition for response.

A new way of making a detailed 3D picture of a diseased area of a tooth

A team of scientists from Glasgow today revealed a new technique that will allow dentists to detect and study the tell-tale signs of tooth decay before too much damage is done.

Speaking at one of the opening sessions at the Institute of Physics conference Photon 04 in Glasgow, Simon Poland outlined a new way of making a detailed 3D picture of a diseased area of a tooth, which could be done while a patient waits.
