Effects of 0.2% Hyaluronic Acid Gel-Impregnated Dental Flosses on Clinical Gingival Parameters

Gingivitis is a common inflammatory lesion caused by the build-up of oral biofilm and is an essential precursor to periodontitis. For its treatment, oral hygiene habits, such as dental flossing, must be improved, and adjunctive materials, such as hyaluronic acid, may be used to reduce plaque formation and gingival inflammation. This study aimed to assess the effects of 0.2% hyaluronic acid gel (Gengigel®)-impregnated dental flosses on the clinical periodontal markers of patients with gingivitis.

This clinical study adopted a split-mouth, randomized controlled trial design. After clinical data were assessed at baseline, and supragingival scaling and planing was performed, bilateral gingivitis regions were randomly allocated to either a test group (hyaluronic acid gel-impregnated floss) or a control group (regular floss) using a computer-generated randomization table. Clinical parameters were recorded at 1, 2, and 4 weeks after treatment.
