The aim of the research will be to evaluate the effects of NSPT on clinical periodontal parameters, level of antioxidants in unstimulated saliva and the levels of biomarkers (VEGF, TGF-β, IL-17) in the GCF in SSc patients in comparison with systemically healthy controls. Twenty systemic sclerosis patients with periodontitis (SS group) and twenty systemically healthy periodontitis patients (P group) will be enrolled in the present study. The results may indicate higher periodontal destruction and antioxidant perturbations in unstimulated saliva of systemic sclerosis patients with periodontitis compared to systemically healthy periodontitis patients.

Periodontal parameters has been recorded on six sites of each tooth using a manual periodontal probe. Activity of antioxidants in unstimulated saliva (GPX, SOD, UA) has been determined using the colorimetric method and commercial kits. Total cytokine levels (VEGF, TGF-β, Il-17) in gingival crevicular fluid were determined using commercial ELISA (enzyme-linked immunosorbent assay) kits . The therapeutic procedure begun with ultrasonic scaling (MiniPiezon, EMS Electro Medical Systems, Switzerland), along with education and motivation of subjects to maintain oral hygiene properly. Periodontal debridement was carried out under local anesthesia, by quadrants, starting from the upper right quadrant at 7-day intervals until the completion of therapy. Instrumentation of all periodontal pockets was processed manually using specialized curettes.
