ObjectivesPrimary Sjögren's syndrome (pSS) is an inflammatory chronic disorder that mainly affects exocrine glands. Additionally, oral infections can aggravate the glandular dysfunction. However, data on primary dental care (PDC) treatment in pSS are scarce. This study aimed to appraise the impact of PDC on Xerostomia Inventory (XI), unstimulated/stimulated salivary flow rates and salivary cytokine profile in pSS.
Methods
Fifty-two pSS patients and 52 sex-/age-matched control participants without systemic autoimmune diseases were comprisedin a prospective study. At inclusion, all participants were assessed through a standardized protocol, measurement of salivary pro-inflammatory cytokines, and underwent PDC. Dental procedures included: oral hygiene guidance, restorative treatment of caries, surgical removal of residual roots and impacted or partially erupted teeth, cysts, supra and subgingival periodontal scaling and treatment of soft tissue disorders (removal of lesions and treatment of opportunistic infections).After 3 months, the clinical/laboratorial assessments were repeated. group (13.3±8.2 vs. 8.6±6.2, p=0.002), whereas periodontal parameters were comparable in both groups (p>0.05). After PDC, 26.9% of pSS patients showed reduction of at least 6 points (clinical improvement) in XI, but mean XI remained unchanged (p=0.285). PDC resulted in increase in mean unstimulated (p<0.001) and stimulated (p=0.001) salivary flow rates in pSS, without change in salivary cytokine profile (p≥0.05).
Results
At inclusion, Decayed, Missing and Filled Teeth (DMFT) index was higher in pSS patients than in control
ConclusionPDC promoted improvement in unstimulated and stimulated salivary flow rates in pSS. This novel finding reinforces the recommendation of this strategy for pSS patients. Clinicaltrials.gov (Identifier: NCT03711214).
