Oral health-related quality of life in different rheumatic diseases.

OBJECTIVES Aim of this cross-sectional study was to investigate oral health-related quality of life (OHRQoL) of patients with different rheumatic diseases. SUBJECTS AND METHODS Patients with rheumatic disease, including rheumatoid arthritis (RA), systemic lupus erythematodes (SLE), systemic sclerosis (SSc), ankylosing spondylitis (AS), psoriatic arthritis (PsA) and Vasculitis were included. OHRQoL was assessed with the German short form of oral health impact profile (OGIP G14). Age, disease duration, leukocytes, c-reactive protein (CRP) and hemoglobin counts were considered as disease related parameters. RESULTS A total of 356 patients, assigned to the groups RA (n=218), SLE (n=36), AS (n=36), PsA (n=33), Vasculitis (n=19) and SSc (n=14) were included. The OHIP G14 sub-scale psychosocial impact differed significantly between groups (p=0.02). The OHIP G14 sum score was also significantly different between groups (p<0.01). A medium sized correlation was found for CRP with OHIP G14 sum score within SLE group (r=0.344, p=0.04). A large correlation was detected for Leukocytes within PsA group (r=0.525, p<0.01). The reliability of the applied OHIP G14 was high. CONCLUSION Patients with rheumatic disease show a reduced OHRQoL, with several differences between the entities. Psychosocial aspects appear to be of relevance and should be considered in multidisciplinary dental care of these patients.
