Background Sjogren’s syndrome is an autoimmune disease that is characterized by the classic symptoms of dry mouth, dry eyes, and arthritis. The most common symptom is called sicca symptoms which consist of keratoconjunctivitis sicca and hyposalivation and xerostomia. Many papers use the term xerostomia and hyposalivation interchangeably. However, these two terms define different conditions. Xerostomia is used to describe the subjective complaint of dry mouth whereas hyposalivation is objectively measured. Objective To examine the correlation between xerostomia, unstimulated salivary flow rate, and oral mucosal dryness in patients with Sjogren’s syndrome. Results Summated xerostomia inventory Indonesian version (SXI-ID_and clinical oral dryness score (CODS) is negatively correlated with unstimulated salivary flow rate. Whereas SXI-ID is positively correlated with CODS. Conclusion Xerostomia is assessed using SXI-ID which is not always followed by hyposalivation. The hyposalivation affects the wettability of oral mucosa, as it negatively correlated with oral mucosa dryness. Further study is needed to investigate the detailed correlation between xerostomia and hyposalivation, and factors affecting them.
