Does Hyaluronic Acid Help Relieve Dry Mouth?
13 de mayo de 2026 actualizado por: Verónica Carolina Schiavo, University of Barcelona
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:
- Does hyaluronic acid improve the sensation of dry mouth?
- What side effects may occur after treatment?
- How long does the effect of the treatment last?
- 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

¿Qué mide el estudio?
Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
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.
Periodo de tiempo: From enrollment to the end of treatment at 6 months
|
Change from baseline in xerostomia severity measured by the Xerostomia Inventory test which ranges from 11 to 55, with lower scores indicating less xerostomia-related impact, at 1 month, 2 months, 3 months, and 6 months after treatment.
|
From enrollment to the end of treatment at 6 months
|
Medidas de resultado secundarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Salivary secretion in patients with xerostomia before and after submucosal infiltration of hyaluronic acid or placebo
Periodo de tiempo: From enrollment to the end of treatment at 6 months
|
Unstimulated and stimulated salivary flow rates measured by standardized saliva collection procedures to classify salivary flow as normal or reduced.
Salivary flow volumes (mL) will be collected over 5 minutes for unstimulated and stimulated saliva at baseline, and at 1 month, 2 months, 3 months, and 6 months after treatment under standardized morning conditions.
|
From enrollment to the end of treatment at 6 months

Periodo de tiempo |
|---|---|---|
|
Presence of cracks, erosions, and ulcers on the lips and oral mucosa following submucosal infiltration of hyaluronic acid vs placebo
Periodo de tiempo: From enrollment to the end of treatment at 6 months
|
Evaluated by standardized visual examination of the oral mucosa, with photographic documentation recorded when lesions are identified, at baseline, and at 1 month, 2 months, 3 months, and 6 months after submucosal infiltration of hyaluronic acid versus placebo.
|
From enrollment to the end of treatment at 6 months
|
|
Patient's sensation of comfort after submucosal infiltration of hyaluronic acid vs placebo
Periodo de tiempo: From enrollment to the end of treatment at 6 months
|
Change from baseline in oral dryness assessed using the Visual Analog Scale (VAS) adapted for xerostomia, which ranges from 0 to 10, where 0 indicates no oral dryness and 10 indicates complete oral dryness; higher scores represent worse xerostomia severity (0 = no dryness; 1-3 = mild dryness; 3-7 = moderate dryness; 7-9 = severe dryness; 10 = total dryness).
