Four years ago, a study conducted at the University of Southern California Center for Biofilms challenged the way many people thought about the Waterpik® Water Flosser. The investigation by Gorur et al showed that a three-second application of pulsating water at 70 psi resulted in up to 99.9% plaque removal from the treated area.

Now a new study has found that the Waterpik® Water Flosser not only removes plaque but does so even more effectively than string floss!  That's good news for both you and your patients.

Waterpik® Water Flosser:
29% More Effective for Removing Plaque than String Floss

Evaluation of the plaque removal efficacy of a Water Flosser compared to string floss.

Methodology:

70 subjects participated in this randomized, single-use, single blind parallel clinical study. Subjects abstained from any oral hygiene for 23-25 hours prior to the appointment. Subjects were screened and assigned to 1 of 2 groups; Waterpik® Water Flosser plus a manual toothbrush or waxed string floss plus a manual toothbrush. Instructions were provided for each product used. Each participant brushed for 2-minutes using the Bass method. Group 1 used the Water Flosser with 500 ml of warm water and group 2 used waxed string floss cleaning all areas between the teeth. Subjects were observed to make sure they covered all areas and followed instructions. Scores were recorded for whole mouth, marginal, approximal, facial, and lingual regions for each subject using the Rustogi Modification Navy Plaque Index.

Results:

The Waterpik® Water Flosser group had a 74% reduction in whole mouth plaque and 82% for approximal plaque compared to 58% and 63% for the strong floss group respectively. The difference between the groups showed the Water Flosser was 29% more effective than string floss for overall plaque removal and 29% for approximal surfaces.

Conclusion:

The Waterpik® Water Flosser is significantly more effective than string floss in removing plaque for all tooth surfaces.
