WaterpikTM Sonic-FusionTM: Significantly More Effective than Sonicare® DiamondClean for Removing Plaque and Improving Gingival Health

Comparison of a Novel Sonic Toothbrush With a Traditional Sonic Toothbrush and Manual Brushing and Flossing on Plaque, Gingival Bleeding, and Inflammation: A Randomized Controlled Clinical Trial

Goyal CR, Qaqish, JG, Schuller R, Lyle D. Compend Contin Educ Dent. 2018;39(suppl 2):14-22.


To determine the effectiveness of WaterpikTM Sonic-FusionTM in reducing plaque and the clinical signs of inflammation as compared to Sonicare® DiamondClean.


This is a randomized, controlled, parallel clinical trial. Thirty five subjects who met the criteria were enrolled into each group. One group used WaterpikTM Sonic-FusionTM, brushing for two minutes and flossing for one minute, and one group used Sonicare® DiamondClean electric toothbrush with DiamondClean Brush Head. Gum Health was measured using bleeding on probing (BOP) and the Modified Gingival Index (MGI) at baseline, two weeks, and four weeks. Plaque was evaluated by the Rustogi Modified Navy Plaque Index (RMNPI). Scores were measured at baseline, two weeks, and four weeks. All subjects were provided written and verbal instructions.


Both Sonic-FusionTM and Sonicare® DiamondClean showed a significant reduction in BOP and MGI from baseline to four weeks (p<0.001). The WaterpikTM Sonic-FusionTM group was significantly more effective than Sonicare® DiamondClean for all clinical parameters, improving BPO by 38%, MGI by 38%, and RMNPI by 36%.


This study demonstrates that the WaterpikTM Sonic-FusionTM is significantly more effective than Sonicare® DiamondClean for improving oral health.
