FRI0392 The relationship between salivary flow rates, oral health assessment and ultrasonographic scoring of the major salivary glands in sjogren syndrome

Background Salivary flow rates (SFR) and oral health were known to be frequently impaired in Sjogren’s syndrome (SjS) due to chronic inflammation and destruction of the salivary glands. Ultrasonography (USG) of major salivary glands (SG-USG) is a non-invasive widely used tool to evaluate salivary glands in SjS. Objectives The aim of the study was to assess the relationships between SFRs, oral health and USG changes of major salivary glands in patients with primary SjS. Methods Fifty-nine SjS patients (F/M:57/2) with the mean age of 52.2±11.5 years. The duration of follow-up period of 9.±7.1 years fulfilling ACR-EULAR classification criteria (2002) were included. Major salivary glands (bilateral parotis and submandibular glands) were scored according to two different scoring systems which are Hocevar A.(0–48) and Milic VD. (0–12). Oral health was assessed by indices. Measurements of whole unstimulated and stimulated SFRs were carried out in patients between 9 a.m. and 10 a.m in the morning. Oral health related quality of life (OHRQoL) as a patient reported outcome measure was evaluated by using Oral health impact profile (OHIP-14). High scores indicated poor OHRQoL status. Pathologic findings in oral health (GM) and USG images (NI) were evaluated by two authors as double-blind. Results Unstimulated SFR (0,2±0,2 ml/min) was correlated with stimulated SFR (1,1±0,7 ml/min) in the whole group (r=0,8 p=0.000). Moderate correlations were seen between unstimulated and stimulated whole SFRs and scores of hypoechogenic areas in bilateral parotid and submandibular glands (p Conclusions Unstimulated and stimulated SFRs were found correlated with the structural changes of major salivary glands. Tooth loss and poor OHRQoL were shown in patients due to reduced salivary outputs. USG images of salivary glands could give insight to physicians about oral health and OHRQoL as outcome measure in patients with SjS. Disclosure of Interest None declared
