Title Sonicare Air Floss is an Effective Plaque Remover
Clinical Question In a patient with gingivitis, is Sonicare Air Floss an effective interdental cleaning device in the reduction of gingivitis and plaque when used on a daily basis?
Clinical Bottom Line Evidence suggests that the Sonicare Air Floss is statistically significant as an effective plaque remover, thereby reducing gingivitis and improving “bleeding on probing,” modified gingival, and plaque indexes.

24170371Rmaile/2013Typodont model teeth: upper central with S. Mutans.Laboratory study
Key resultsA prototype Air Floss with a microburst of 115 μL over .033 seconds was used to detach S. Mutans biofilm from interproximal surfaces of maxillary centrals. 95% of the biofilm was removed on surfaces closest to the tip of the nozzle, 62% at ½ the distance labio-palatally, and 8% removal of biofim farthest away from the tip of the nozzle. Most effective biofilm removal was achieved when the nozzle was aimed at mid-tooth occluso-gingivally.
22435321Sharma/201282 subjects randomized into 2 groups; Waterpik and toothbrush or Air Floss and toothbrushRandomized Controlled Trial
Key resultsBoth Air Floss (AF) and Waterpik (WF) significantly improved the MGI, but the WF was 80% more effective than the AF for the whole mouth. Both AF and WF significantly reduced BOP, but WF outperformed AF (p=0.02) for the whole mouth. For the PI, WF removed 50.9% plaque from the whole mouth, while AF removed 30%.

Comments on
The Evidence
Validity: The Rmaile study showed good results from the Sonicare Air Floss, but since the study was conducted in vitro, the results are not as valid as the Sharma study, which was a randomized controlled trial. The Sharma sample size was adequate with all participants completing the study. All groups that were studied were treated the same in the Sharma study. This study was done over a period of 4 weeks. Waterpik sponsored the article, so study bias is possible, but the Sonicare Air Floss’ results were still proven to be significant. Perspective: Both studies showed the Sonicare Air Floss to be an effective plaque removing aid. Even though the comparison showed Waterpik to be more effective than the Sonicare Air Floss, significant results were obtained also with the use of the Sonicare Air Floss. The Sonicare Air Floss was shown to reduce plaque interproximal areas by 48% and reduce gingivitis by 22.8%.
Applicability Both studies are specific to the PICO question. Both studies are also applicable to dental professionals who are recommending products to their patients to improve their oral hygiene.
