Effect of dental care on the oral health of Sjögren’s syndrome patients.

Sjögren’s syndrome (SS) is a chronic, systemic autoimmune disease affecting the exocrine glands, particularly the salivary and lacrimal glands. Xerostomia is a major feature of this syndrome and greatly affects patient quality of life. The most typical clinical signs associated with hyposalivation are dysgeusia and dysosmia, dental caries, candidiasis, periodontal disease, gland inflammation, mucositis and oral ulcers. The aims are to investigate on Plaque Index (PI) and Gingival Index (GI) before and after dental care of SS patients. Fifty-two consecutive patients (mean age 48.9±2 years) were analysed. At T0, (baseline) T1 (3 months after T0) and T2 (6 months after T0), a Plaque Index and a Gingival Index were calculated. The statistical analysis was performed using one-way ANOVA test. If distribution was not normal, Friedman test was chosen instead of ANOVA. Dunn’s multiple comparison procedure was performed as post-hoc (IBM SPSS Statistics 21 software). A statistically significant decrease was observed both in PI and in GI between T0 and T1, T1 and T2, T0 and T2 (P less than 0.05).
