Recent findings published in the Journal of Antimicrobial Chemotherapy reveal that the cranberry may be the next new weapon in the fight for good oral health. Researchers have discovered that natural compounds in cranberries may help ward off periodontitis, or severe gum disease, by serving as a powerful anti-inflammatory agent. This anti-inflammatory effect may be attributed to unique compounds in the fruit that prevent P. gingivalis bacteria from adhering to the teeth below the gum line. This new research offers great promise for the estimated 67 million Americans affected by periodontitis, the primary cause of tooth loss in adults.

Cranberries are widely known for their "anti-adhesion" activity, which helps guard the body from certain harmful bacteria that cause urinary tract infections (UTIs), stomach ulcers and gum disease. This anti-adhesion activity is primarily due to proanthocyanidins (PACs) found naturally in cranberries and other foods. Cranberry PACs, however, contain a unique A-type structure that is responsible for this anti-adhesion mechanism of action, while most other foods contain only the more-common B-type PACs.

In this study, researchers discovered that cranberry compounds can reduce the growth of P. gingivalis and subsequent plaque development -- the initial step in the development of periodontitis. Periodontitis occurs when inflammation or infection of the gums is left untreated or treatment is delayed. Infection and inflammation spreads from the gums to the ligaments and bones that support the teeth and eventually leads to tooth loss. This study builds upon earlier research published in the Journal of Dental Research, where scientists discovered that cells treated with cranberry juice showed significantly less inflammation than cells that were not treated.

"We know that brushing, flossing, and regular dental cleanings reduces the risk of developing periodontitis by helping to prevent the onset of gingivitis, or gum infection," said Julie Labrecque, from the University of Laval and lead researcher of the study. "With this new study, cranberries may provide an interesting ingredient in the development of new therapeutic approaches for treatment of periodontitis."

In addition to preventing the growth of P. gingivalis, previous research has shown that cranberry compounds may also prevent certain oral bacteria from directly destroying gum tissue itself -- another major factor contributing to periodontitis. This may have more widespread implications as recent studies have also linked severe gum disease with an increased likelihood for heart disease and stroke.

Ocean Spray is an agricultural cooperative owned by more than 650 cranberry growers in Massachusetts, Wisconsin, New Jersey, Oregon, Washington, British Columbia, and other parts of Canada as well as more than 100 Florida grapefruit growers. Ocean Spray was formed 75 years ago by three cranberry growers from Massachusetts and New Jersey. Florida grapefruit growers joined the Cooperative in 1976. Ocean Spray is North America's leading producer of canned and bottled juices and juice drinks, and has been the best-selling brand name in the canned and bottled juice category since 1981. Ocean Spray posted fiscal 2005 gross sales of about $1.4 billion.
