Rotation oscillation toothbrushes proven more effective than ’sonic’ technology

Nearly four decades of research conclude that power toothbrushes with rotation oscillation action, such as the Oral-B 3D Excel, are demonstrably more effective in removing plaque and reducing gingivitis than other types of power toothbrushes — including those featuring “sonic” technology — according to an international study announced today at the Forsyth Institute conference on evidence-based dentistry.

Half of adults age 18 or older have some evidence of gingivitis, the earliest form of periodontal disease. Gingivitis is reversible with professional treatment and good at-home oral care, but if left untreated, can lead to periodontal disease and possible tooth and bone loss.

The comprehensive study, conducted by the Cochrane Collaboration, a British-based non-profit health research group, reviewed data from all available published studies conducted between 1964 and 2001, involving more than 2,500 participants. The study independently concluded that toothbrushes that rotate and oscillate, a technology pioneered by Oral-B in 1991, are more effective than any other type of toothbrush — manual or “sonic” — in reducing plaque and gingivitis.

“For over a decade, consumers and the dental community have been bombarded with conflicting information about which type of toothbrushes — manual, power or “sonic” — work best,” said Dr. Paul Warren, Vice President of Clinical Research for Oral-B. “This study clears up any confusion and conclusively proves that Oral-B power toothbrush technology is superior in keeping teeth and gums healthy.”

The flagship Oral-B 3D Excel power toothbrush builds upon the original rotation oscillation movement with a patented 3D technology that adds high-speed in-and-out pulsations. With its unique combination of the compact brush head and the patented 3D action, the Oral-B 3D Excel cleans below the gum line to prevent and even reverse gum disease. Additionally, 3D technology has been clinically proven to whiten teeth better than “sonic” technology.

“Oral-B has been and still is at the forefront of dental technology and the Cochrane study confirms decades of our own research and development,” said Bruce Cleverly, President, Gillette Oral Care. “We’ve always known, and the Cochrane study confirms our 3D Excel power toothbrush technology is the best at reducing plaque and gingivitis.”

Power toothbrushes included in the Cochrane Collaboration study included brushes produced by Braun Oral-B, Philips Sonicare, Interplak, Rowenta and Ultrasonex. Detailed findings are to be published in the January 2003 issue of The Cochrane Library.
