Efficacy of Submucosal Hyaluronic Acid Infiltration in Improving the Sensation of Dry Mouth in Patients With Xerostomia: A Double-Blind Randomized Clinical Trial.
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
• Patients over 18 years of age
• Patients reporting symptoms compatible with xerostomia for at least one year
• Patients who agree to cooperate in the study, comply with the follow-up plan, and sign the informed consent
