Waterpik^TM Sonic-Fusion^TM: Up to 2X as Effective as Regular Brushing & Flossing for Improving Gingival Health

Objective

To determine the effectiveness of the Waterpik^TM Sonic-Fusion^TM in reducing plaque and clinical signs of inflammation as compared to manual brushing and flossing.

Methodology

One hundred and five subjects were randomized into three groups in this 4-week, parallel, single-blind, clinical trial. There were two experimental groups: Sonic-Fusion^TM with full (SFF) or compact (SFC) brush head. The control group use a manual brush and floss (MTF). Gingival health was measured using bleeding on probing (BOP) and the Modified Gingival Index (MGI) at baseline, 2-weeks, and 4-weeks. The Rustogi Modified Navy Plaque Index (RMNPI) scores were measured at baseline, 2-weeks, and 4-weeks. All subjects were provided written and verbal instructions.

Results

All groups showed a significant reduction in BOP and MGI from baseline to 4-weeks (p<0.001). Both Sonic-Fusion^TM groups were significantly more effective than the MTF group for BOP, MGI, and RMNPI for whole mouth and interproximal areas.

Conclusion

This study demonstrates that the Waterpik^TM Sonic-Fusion^TM is up to twice as effective as traditional brushing and flossing for improving gingival health.
