A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of two different mouthwashes containing chlorhexidine, with and without hyaluronic acid, on the healing of surgical wounds following third molar surgery. Patients will be randomly assigned to one of three groups: one receiving the chlorhexidine plus hyaluronic acid mouthwash, another receiving chlorhexidine alone, and a control group receiving a placebo. The healing process will be monitored through photographs and a Wound Healing Index at multiple time points post-surgery. The study aims to determine if the addition of hyaluronic acid enhances wound healing compared to chlorhexidine alone.

Why it matters

Potential benefit: If successful, this approach could lead to improved healing outcomes for patients undergoing third molar surgery.

How similar studies have gone: Previous studies have shown promising results with chlorhexidine in wound healing, but the combination with hyaluronic acid is a novel approach.
