Efficacy of water flossing on clinical parameters of inflammation and plaque: A 4-week randomized controlled trial.

Abstract

BACKGROUND:

The primary prevention of periodontitis is controlling gingivitis daily. The study objective was to compare the efficacy of a pulsating water flosser to a pulsating water flosser infused with air microbubbles on clinical signs of inflammation and plaque.

METHODS:

One hundred and five participants were enrolled in this single-blind, single-centre, parallel, 4-week, IRB/IEC-approved clinical trial. Participants were randomly assigned to one of three groups: water flosser (WF) plus manual toothbrush, water flosser infused with microbubbles of air (MBWF) plus manual toothbrush, or dental floss (DF) plus manual toothbrush. Bleeding on probing (BOP), Modified Gingival Index (MGI) and Rustogi Modification Navy Plaque Index (RMNPI) scores were recorded at baseline, 2 and 4 weeks.

RESULTS:

All participants completed the study (n = 105). All groups showed a statistically significant reduction for BOP, MGI and RMNPI at 4 weeks (p < 0.05, except DF marginal RMNPI). The WF group showed a statistically significant greater reduction in whole mouth BOP (0.41) compared to MBWF (0.32) and DF (0.19). This was also true for MGI (0.37, 0.30 and 0.20, respectively) and RMNPI (0.13, 0.11 and 0.06, respectively; p < 0.05 for all comparisons). No adverse events were reported.

CONCLUSION:

This study demonstrates that a manual toothbrush and water flosser, with or without microbubbles, is an effective oral care regimen for controlling gingivitis over 4 weeks.
