The WaterpikTM Water Flosser Significantly Improves Oral Health Benefits Over a High-End Oscillating Electric Toothbrush

Efficacy of the Use of a Water Flosser in Addition to an Electric Toothbrush on Clinical Signs of Inflammation: 4-Week Randomized Controlled Trial

To determine incremental efficacy of adding a WaterpikTM water flosser to a high-end Oral-B® electric toothbrush, on the reduction of plaque and gingivitis, in comparison to brushing alone with the electric toothbrush.


Seventy subjects completed this four week, randomized controlled trial. Subjects were assigned to one of two groups; WaterpikTM water flosser plus Oral-B® Pro 2000 with Precision Clean brush head (WF); or Oral-B Pro 2000 with Precision Clean brush alone (OR). Gingivitis was evaluated by Bleeding on Probing (BOP) and Modified Gingival Index (MGI). Plaque was evaluated by Rustogi Modification of Navy Plaque Index (RMNPI). Data was collected at baseline, two weeks, and four weeks. Subjects were provided with manufacturer instructions on how to use.


Both groups showed a significant reduction from baseline in BOP, MGI, and RMNPI at two weeks, and four weeks p<0.001. The WF group had significantly better results compared to the OR group for all clinical parameters, improving the reduction of BOP by 37%, MGI by 36%, and RMNPI by 33%, after four weeks.


This study demonstrates that the addition of a WaterpikTM water flosser to the use of a high quality oscillating electric toothbrush is significantly more effective versus using the electric toothbrush alone.
