Study supports germ-killing features of Listerine

Sep 23, 2009

The results of a new clinical study demonstrate that the plaque and gingivitis germ-killing action of Listerine Antiseptic significantly reduces the amount of germs that travel from the mouth to the bloodstream in people with mild to moderate gingivitis, according to a company press release.

The randomized, controlled, crossover study conducted at the University of Medicine and Dentistry of New Jersey found that participants using Listerine Antiseptic as directed experienced a reduction in aerobic and anaerobic bacteria in the bloodstream (67.3% and 70.3%, respectively).

The results will be presented during a symposium at the American Dental Association (ADA) annual session in Hawaii.

"The findings from this study serve as compelling evidence to further the theory that plaque and gingivitis germs that migrate from the mouth to the bloodstream may contribute to broader health problems such as diabetes and heart disease," said Daniel Fine, D.M.D., chair of the Department of Oral Biology at the University of Medicine and Dentistry of New Jersey and lead investigator of the study.

"While additional research in this area is necessary," he continued, "this study undoubtedly proves that Listerine Antiseptic kills the germs in your mouth that cause plaque and gingivitis before they have a chance to travel to the bloodstream."

The study is the first in a new generation of research evaluating whether a regular oral hygiene regimen with Johnson & Johnson products can have a positive effect on whole body health, added Marcelo Araujo, D.D.S., Ph.D., associate director of scientific and professional affairs for Johnson & Johnson.
