A String around Your Finger: Do We Really Need to Floss?

A History and Update of Fluoride Dentifrices
Write Review

A String around Your Finger: Do We Really Need to Floss? will review current literature on the effectiveness of flossing and other interdental cleaning methods. In light of emerging evidence regarding limited evidence on the effectiveness of flossing to reduce caries rates and treat periodontitis, this course seeks to identify other methods of interdental cleaning that are focused on optimal delivery of care for patients based upon their underlying risks and oral health conditions. This course will examine the 2011 Cochrane systematic review upon which the government based its decision to omit the recommendation to floss from the 2015-2020 Dietary Guidelines for Americans, the 2015 European Federation of Periodontology’s publication evaluating the evidence for efficacy of interdental cleaning methods in patients with periodontitis, as well as the broader literature and scientific rationale behind flossing and interdental cleaning. Finally, this course will evaluate the utility of interdental cleaning methods in patients with high caries risk, periodontal health, gingivitis, and periodontitis.
