Official title
Efficacy of Submucosal Hyaluronic Acid Infiltration in Improving the Sensation of Dry Mouth in Patients With Xerostomia: A Double-Blind Randomized Clinical Trial.
Overview
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
Interventions
- Device Submucosal infiltration of non reticulated hyaluronic acid
Submucosal infiltration of non reticulated hyaluronic acid will be administered all over the buccal cavity (floor of the mouth, yugal mucosa, lips) - Device Submucosal infiltration of Placebo
Submucosal infiltration of placebo (Sterile 0.9% Sodium Chloride Solution for Injection) will be administered all over the buccal cavity (floor of the mouth, yugal mucosa, lips)
Primary outcome measures
- Efficacy of submucosal hyaluronic acid infiltration in the oral mucosa, compared to placebo infiltration, in improving symptoms associated with mucosal dehydration in patients with xerostomia. [Time frame: From enrollment to the end of treatment at 6 months]
Secondary outcome measures (1)
- Salivary secretion in patients with xerostomia before and after submucosal infiltration of hyaluronic acid or placebo [Time frame: From enrollment to the end of treatment at 6 months]
