Effectiveness of HydrogenPeroxie, Hyaluronic Acid, Chlorhexidine Mouthwashes in Gingivitis Management: A Randomized, Triple-Blind, Controlled Clinical Trial
Effectiveness of HydrogenPeroxie, Hyaluronic Acid, Chlorhexidine Mouthwashes in Gingivitis Management: A Randomized, Triple-Blind, Controlled Clinical Trial
This randomized, triple-blind clinical trial is designed to evaluate the efficacy of four different mouthwash formulations - hydrogen peroxide with hyaluronic acid, hyaluronic acid alone, chlorhexidine, and placebo - in four parallel arms. The study will take place at multiple centers, starting on June 1, 2025, and is expected to conclude by October 1, 2026. There is no external funding source for this study.
Eligible participants include systemically healthy individuals aged 18 to 35 years with a gingival and plaque index score of 1 or higher. Individuals with systemic or oral diseases will be excluded. Participants will be randomly assigned to one of four groups, each receiving a different mouthwash formulation for twice-daily use, following standardized oral hygiene instructions.
The potential benefit includes a reduced risk of gingivitis progression to periodontitis. There are no significant anticipated risks, though mild oral discomfort or taste alteration may occur.
This randomized, triple-blind clinical trial aims to compare the effectiveness and safety of four different mouthwash formulations in managing gingivitis. The test group will use a mouthwash containing hydrogen peroxide (H2O2 1.80% )and hyaluronic acid (HA 0.10%). The three comparator groups will receive either chlorhexidine (CHX 0.12%), hyaluronic acid (HA 0.12%) (high molecular weight) alone, or a placebo mouthwash.
A total of four parallel arms will be used. Participants will be randomly assigned using a computer-generated randomization list. Blinding will apply to participants, clinical evaluators, and data analysts to maintain objectivity (triple-blind design).
Each participant will use the assigned mouthwash twice daily for three weeks, following standard oral hygiene instructions.
The primary outcomes will be changes in gingival inflammation, plaque accumulation, and bleeding on probing, assessed using the Gingival Index (GI), Plaque Index (PI), and Bleeding on Probing (BOP). Measurements will be taken at baseline, and after one, two, and three weeks of intervention.
The secondary outcomes will include reported side effects such as taste alteration, tooth discoloration, and overall comfort using the mouthwash.
The study is designed to determine which formulation offers the best balance of clinical effectiveness and patient acceptability in gingivitis management.
