Comparing the effectiveness of water flosser and dental floss in plaque reduction among adults: A systematic review

Abstract

Introduction:

Interdental aids such as dental floss and water flossers have been found to be effective in removing interdental plaque. This systematic review aimed to compare the available data on the efficacy of dental floss and water flossers in plaque removal among adults.

Materials and Methods:

Five databases: PubMed, Scopus, Cochrane, ScienceDirect, Lilac, and Google Scholar were searched from January 1, 2002, to October 31, 2022, to obtain the relevant articles. Based on the search strategy, the titles of the studies were screened independently by two reviewers. Randomized controlled trials were included in the review, in which the study participants were given either dental floss or water flosser. Reduction in plaque scores was the outcome that was assessed. Seven articles met the eligibility criteria and were further processed for qualitative analysis.

Results:

The majority of the studies favored water flossers over dental floss in plaque reduction. Water flosser was also found to be effective in removing plaque from inaccessible interproximal areas of the tooth surfaces as compared to dental floss.

Conclusion:

Based on the scope of this review, results suggest that water flossers can be used as an effective alternative to dental floss in patients with manual dexterity, patients undergoing orthodontic treatment, and patients with dental prostheses.
