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.

Tetracycline plus teeth equal gray smile
Many adults over age 35 cover their mouth to avoid smiling in public in order to hide their teeth darkened by tetracycline stains. Typically, invasive as well as costly treatment options, such as veneers, crowns and bonding, served as the only treatment options to help these individuals hide such stains and boost their self-esteem.

Periodontal therapy may help diabetic patients improve sugar control
The results suggest that periodontal therapy may reduce a diabetic patient's HbA1c count by as much as 20 percent at three and six months following treatment. According to the American Diabetes Association, HbA1c provides patients with a picture of their average blood sugar changes in the past two to three months and gives them a good idea of how well their diabetes treatment plan is working. A healthy HbA1c count is between the ranges of 4.0 to 6.0.

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.

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.

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.

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.
