Oral distress in primary Sjögren’s syndrome: implications for health-related quality of life

Abstract

The aims of the study were to evaluate oral distress in patients with primary Sjögren's syndrome (pSS) compared with age- and sex-matched Norwegian normative data, to estimate the occurrence of oral symptoms in pSS, and to evaluate the impact of oral distress on health-related quality of life (HRQoL). The Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) was used to assess HRQoL, and the Oral Health Impact Profile 14 (OHIP-14) was used to measure oral distress. Of the 246 pSS patients invited to participate in the study, 177 (72%) responded. Data were analysed for the female participants (n = 163). Significant deviations from normative estimates were found in all OHIP-14 item results, and the findings indicated a high level of oral distress among the pSS patients. Health-related quality of life was decreased among pSS patients, with the largest deviations from normative estimates related to general health and role physical. The patients with high levels of oral distress scored significantly lower than patients with low levels of oral distress in five of the SF-36 subscales, indicating that oral conditions have a marked impact on general quality of life. In conclusion, oral distress in pSS is pronounced and severe, and should receive increased attention with a view to improving the quality of life for these patients.
