Hydrogen Peroxide (1.80%): Acts as an antiseptic agent, releasing oxygen that helps in reducing bacterial load and disrupting biofilms associated with gingivitis. * Hyaluronic Acid (0.10%): A naturally occurring polysaccharide known for its anti-inflammatory and tissue-regenerative properties, aiding in the healing of gingival tissues Clinical studies have demonstrated the efficacy of Perhyal in managing gingivitis. In a randomized controlled trial, Perhyal showed a significant reduction in gingival inflammation compared to placebo, with no reported adverse effects over 21 days.

This intervention involves the use of a mouthwash containing hyaluronic acid (0.12%) of high molecular weight, without any additional active agents. Hyaluronic acid is a naturally occurring substance known for its anti-inflammatory and wound-healing properties. It supports gingival tissue regeneration and hydration, which may contribute to reducing signs of gingivitis such as redness, swelling, and bleeding. Participants assigned to this arm will rinse with 10 mL of the solution twice daily for three weeks, following standardized oral hygiene instructions. This arm serves to evaluate the independent therapeutic effect of hyaluronic acid in managing gingival inflammation.

This intervention uses a commercially available chlorhexidine gluconate 0.12% mouthwash, widely recognized for its strong antimicrobial properties. Chlorhexidine is considered a gold-standard agent for chemical plaque control and is effective in reducing bacterial load, gingival inflammation, and bleeding. Participants in this group will rinse with 10 mL of the solution twice daily for three weeks, in addition to maintaining regular oral hygiene practices.

This placebo mouthwash was specially formulated to visually and sensorially resemble the active mouthwash products without containing any active therapeutic ingredients. It was prepared in the AwaMedica laboratory using 1 liter of distilled water, 98.5% distilled water, 2 mL of glycerin for mild viscosity, 5 mL of vanilla flavoring for taste masking, and 8 mL of brown food coloring to match the appearance of chlorhexidine. The solution was stored in 120 mL opaque brown bottles, each labeled only with the participant number to ensure blinding. Participants will use 10 mL of the placebo rinse twice daily for three weeks, following the same oral hygiene protocol as other groups.
