We aimed to evaluate the periodontal status and to identify potential relation with SSc-specific parameters as well as serum lipid profile in a cross-sectional study on consecutive SSc. Standard assessments comprised dual, rheumatologic (disease subtype, clinical spectrum, inflammatory, immunological, lipid metabolism - total cholesterol and fractions, triglycerides), and dental evaluation (plaque index, bleeding on probing, pocket depth, clinical attachment level). 70.96% SSc developed oral manifestations, 51.61% periodontal disease, while one third severe aggressive periodontitis, particularly in diffuse SSc (p<0.05). Abnormal lipid pattern (low serum HDL- and high LDL-cholesterol, increased serum triglycerides, without significant modification in total cholesterol level) significantly correlated with diffuse SSc and skin involvement, disease duration, anti-topoisomerase 1 positivity, SSc activity and severity, as well as periodontitis (p<0.05). Our results clearly define an association between the presence and severity of periodontal disease and lipid anomalies in SSc, suggesting a potential link with early atherosclerosis via gingival inflammation and altered lipid metabolism.
