Dental and Periodontal Status of Patients With Sjögren's Syndrome.

Sjögren's syndrome (SS) is a rare chronic systemic autoimmune disease characterized by destruction of the exocrine glands, including the salivary glands.The lack of saliva exposes the patient to dental caries, and dental wear although this has rarely been shown in Sjögren's patients. Moreover, these patients seem to have more inflammation and gingival recession, although this has not been clearly identified in the literature. Our main objective is to assess the prevalence of dental wear and gingival recession in patients with Sjögren's syndrome by analyzing of the Basic Erosive Wear Examination (BEWE) score for erosions, Basic Erosive Wear Abrasion (BEWA) score for attrition and percentage of sites with periodontal recessions greater than 3 mm in relation to the total number of sites. Our secondary objectives are to investigate a correlation between the prevalence of dental and gingival wear, gingival inflammation, Decayed, Missing, and Filled Teeth (DMFT) index and (1) salivary parameters and (2) oral quality of life. The salivary samples will be kept in a biological collection within the URP2496 for later analysis (biological collection CB-SJO).
