Efficacy of dental floss in the management of gingival health: a randomized controlled clinical trial.

Objectives: This randomized controlled clinical trial evaluated the efficacy of dental floss as a supplement to toothbrushing in support of gingival health in adults.

Materials And Methods: Seventy-five systemically healthy subjects, non-smokers, without loss of interproximal periodontal attachment and with more than 15% of the interproximal sites presenting with gingival bleeding were randomized into two groups either performing toothbrushing supplemented by dental floss (TB + DF) or toothbrushing (TB) alone. Over a 60-day period, participating subjects weekly received oral hygiene instruction and supervised personal and professional plaque removal by applying the devices assigned for the group.
