6.1Introduction
This chapter summarizes the orofacial involvement in Sjögren syndrome (SS). Oral manifestations of SS are mainly xerostomia and hyposalivation, autoimmune sialadenitis causing salivary gland swelling, and secondary manifestations such as dental caries, oral candidiasis, bacterial sialadenitis, oral malodour, and oral ulcers. These secondary manifestations are the first features of the disease to become evident in approximately half of the patients with primary SS, and their identification is important for early diagnosis. Furthermore, as most SS patients consider oral complications a major factor of quality of life deterioration [1], their treatment should be a priority.
6.2Definitions
Xerostomia, the subjective complaint of oral dryness, is the most common salivary complaint among patients with SS, but this symptom is not specific for SS. The symptom of xerostomia may or may not reflect decreased salivation (hyposalivation). Hyposalivation is usually defined as an unstimulated whole salivary flow rate <0.1 mL/min.
6.3Objective Determination of Salivary Flow
The normal salivary flow rate varies widely from person to person. Thus, unless baseline salivary flow rates for individual patients are known, it is rarely possible to determine if there has been a reduction in salivary flow.
Unstimulated salivary flow rate (USFR) measurement of whole saliva uses a simple draining test for 5 min at rest. If the saliva produced during this test is less or equal to 0.1 mL/min, the patient has hyposalivation. Normal and reference values are shown in Table 6.1 [2, 3].
The Saxon test is a simple, reproducible, and low-cost test for xerostomia, which involves chewing on a folded sterile sponge for 2 min. Saliva production is quantified by weighing the sponge before and after chewing. Normal control subjects produce ³2.75 g of saliva in 2 min [4].
Because salivary flow rates vary over time for each individual, the salivary tests used as a diagnostic aid for SS diagnosis should be performed on several occasions [5].
