Treatment of Oral Dryness in Sjögren Syndrome with Severe Salivary Gland Dysfunction

When Sjögren syndrome presents with severe salivary gland dysfunction and no residual glandular function, gland stimulation is no longer a viable option — the therapeutic strategy shifts toward direct relief and oral-health protection.

Clinical Scenario

Sjögren syndrome with oral dryness and severe salivary gland dysfunction: unstimulated whole salivary flow <0.1 mL/min, stimulated whole salivary flow <0.1 mL/min, and no residual glandular function. The salivary glands cannot be stimulated by pharmacological or non-pharmacological means in this setting.

Treatment Approach

Saliva substitution is the preferred approach for symptom relief, combined with dedicated caries-prevention measures that address the heightened dental risk — the full protocol specifies product selection criteria, preparation forms, and the complete management algorithm.

Saliva substitution should be considered the preferred therapeutic approach to alleviate symptoms in patients with no residual glandular function (severe glandular dysfunction), in whom salivary glands cannot be stimulated, either by pharmacological or non-pharmacological interventions.
The ideal preparation will have a neutral pH and contain fluoride and other electrolytes, mimicking the composition of natural saliva; saliva substitutes are available commercially in the form of oral sprays, gels and rinses.
Whether or not a saliva substitute is used, a neutral pH sodium fluoride gel should be prescribed to all patients with severe salivary dysfunction to prevent rampant caries.
