Introduction: This randomised, single-blind, controlled study aimed to compare daily adjunctive use of an ultrasonic water irrigation device to dental floss in controlling plaque and gingival inflammation in patients with gingivitis.
Methods: Participants were randomly allocated to either daily use of an ultrasonic water irrigator or dental floss as an adjunct to manual toothbrushing for 4 weeks, with periodontal assessment repeated at 1 and 4 weeks after baseline (Rustogi Modified Navy Plaque Index [PI], Loe and Silness Gingival Index [GI] and bleeding on marginal probing [BOMP]).
Results: Sixty-two participants completed the investigation.
