Does Hyaluronic Acid Help Relieve Dry Mouth?
Recruiting now · Not applicable · Has a placebo group
Conditions studied: Xerostomia
In brief
The goal of this clinical trial is to learn if hyaluronic acid infiltration helps relieve dry mouth symptoms in adults with xerostomia. It will also assess the safety and duration of the treatment's effects. The main questions it aims to answer are: 1. Does hyaluronic acid improve the sensation of dry mouth? 2. What side effects may occur after treatment? 3. How long does the effect of the treatment last? 4. Are there changes in salivary flow and pH after treatment? Researchers will compare hyaluronic acid to a placebo (a look-alike substance with no active ingredient) to determine its effectiveness. Participants will: Receive submucosal injection of either hyaluronic acid or placebo Visit the clinic once a month for 6 months for follow-up evaluations Not be required to perform any tasks at home
