Diagnostic Interest of the Buccal Schirmer Test in Xerostomia During Sjögren's Syndrome: XERODIAG

Sponsor: University Tunis El Manar

Summary

Xerostomia is a common and very bothersome manifestation that impairs the quality of life in Sjogren's syndrome. Its diagnosis mainly relies on the measurement of salivary flow (SF). Performing this test is unpleasant for the patient, lacks precision, can be influenced by certain conditions, and requires good patient cooperation. Other alternatives such as the buccal Schirmer test can be used. The aim of this study is to demonstrate the non-inferiority of the buccal Schirmer test compared to SF measurement. This is a diagnostic study comparing a group of patients (n=90) with Sjogren's syndrome (SS) and normal SF (≥0.1 ml/minute) to a group of patients with SS and decreased SF (\<0.1 ml/minute).
