CHICAGO August 5, 2008 In dental offices all over the world, patients are often told they are not flossing enough or instructed to floss more. As the old saying goes, you only need to floss the teeth you want to keep. After all, not flossing regularly can lead to tooth decay and to periodontal disease, the leading cause of tooth loss in adults.

A recent study published in the Journal of Periodontology (JOP), the official publication of the American Academy of Periodontology (AAP) demonstrates that including flossing as part of one's routine oral care can actually help reduce the amount of gum disease-causing bacteria found in the mouth, therefore contributing to healthy teeth and gums.

The study, conducted at New York University, examined 51 sets of twins between the ages of 12 and 21. Each set was randomly assigned a 2-week treatment regimen with one twin brushing with a manual toothbrush and toothpaste and the other twin brushing with a manual toothbrush and toothpaste and flossing. At the end of the two week trial, samples were taken from both pairs of twins and compared for levels of bacteria commonly associated with periodontal disease.

The study findings indicated that those twins who did not floss had significantly more of the bacteria associated with periodontal disease when compared to the matching twin who flossed in addition to tooth-brushing with toothpaste.

"This study illustrates the impact flossing can have on oral health. The twins experimental model is a powerful tool to help sort out genetic and environmental factors that often confound the interpretation of treatment studies. This study demonstrates that flossing can have an important and favorable impact on an individual, as compared to that of a non-flossing individual with similar genetics and possibly similar habits," explains Dr. Kenneth Kornman, editor or the Journal of Periodontology. "Twins tend to share the same or similar environmen
