Used by patients in a home setting, the floss is inserted between teeth to mechanically remove plaque and food particles. This mechanical action aids in the treatment and prevention of gingivitis and reduction of tooth decay. The device is a simple, non-powered tool requiring no external processing or clinical interpretation. ## Clinical Evidence Four clinical trials were provided to support the gingivitis treatment and prevention indication. Studies evaluated the effectiveness of dental flossing as an adjunct to tooth brushing compared to brushing alone. Results collectively demonstrated that the physical removal of plaque via flossing is effective for the treatment and prevention of gingivitis. Floss treatments were reported as well-tolerated with no safety issues. ## Technological Characteristics Manual dental floss; polytetrafluoroethylene (PTFE) monofilament fiber; coating includes beeswax, gum arabic, water, and flavor. Mechanical plaque removal principle. Non-powered, standalone device. ## Regulatory Identification Dental floss is a string-like device made of cotton or other fibers intended to remove plaque and food particles from between the teeth to reduce tooth decay. The fibers of the device may be coated with wax for easier use. ## Predicate Devices - Glide Comfort Plus Dental Floss - Oral-B Toothbrush ([K073224](/device/K073224.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The floss was developed to improve ease of sliding between tight spaces to achieve effective plaque removal. Each of the materials that could come in contact with the user of this device is comprised of well-defined materials that are safe for use in the oral cavity. Indication for Use: To remove plaque and food particles from between the teeth as part of a comprehensive dental treatment program to reduce tooth decay and to treat and prevent gingivitis. Supporting Information: Two substantially equivalent predicates have been provided, as well as clinical data to support the expanded indication. - Currently marketed Glide Comfort Plus Dental Floss has the same design and . manufacturing process as the Crest Glide Dental Floss and is indicated for removal of plaque and prevention of tooth decay. Crest Glide Dental Floss uses the same mechanism of action (mechanical removal of plaque) to provide treatment and prevention of gingivitis. There are no new issues of safety or effectiveness. - . Currently marketed Oral-B Toothbrush is indicated for treating and preventing gingivitis and uses the same mechanism of action as Crest Glide Dental Floss (mechanical removal of plaque) to achieve this benefit. There are no new issues of safety or effectiveness. - Data from four clinical trials are provided that collectively show the addition of dental . floss to tooth brushing is effective at treatment and prevention of gingivitis via the ## SEP 2 4 2009 İ {1}------------------------------------------------ physical removal of plaque. The floss treatments in these studies were well tolerated with no safety issues. Conclusions: Crest Glide Dental Floss is substantially equivalent to Glide Comfort Plus Dental Floss and Oral-B Toothbrush without raising any new safety and effectiveness issues. In addition, clinical data support the indication of treatment and prevention of gingivitis for dental floss above that provided by tooth brushing alone. #### Bibliography 1 - Assessment of treatment responses to dental flossing in twins.
