The study enrolled 150 participants, 50 chronic periodontitis with head and neck cancer post radiotherapy (CP+HNC post-RT) patients, 50 chronic periodontitis (CP) without HNC patients, and 50 healthy controls. Clinical Attachment Loss (CAL), Probing Pocket Depth (PPD), Plaque Index (PI), and Gingival Bleeding Index (GBI) were recorded. An enzyme-linked immunosorbent assay (ELISA) was constructed to quantify serum (suPAR) levels. Stage and grade of periodontitis were stage III-IV, grade C in patients (CP+HNC post-RT), stage I-III, grade A/B in patients (CP without HNC), and absent in (healthy). Chronic periodontitis with HNC post-RT patients presented a significantly higher proportion of suPAR levels (506.7 pg/ml) compared to chronic periodontitis without HNC and healthy controls (423.08 pg/ml and 255.9 pg/ml), respectively. A significant positive correlation was found between serum suPAR levels and CAL, PPD, PI, and GBI in the periodontal disease groups. ROC results of suPAR (AUC=0.976 for CP+HNC post-RT, AUC=0.872 for CP without HNC). Hyposalivation appeared in patients (CP+HNC post-RT; 0.15 \\[0.11-0.23\\] ml/min, P=0.001) and (CP without HNC; 0.30 \\[0.25-0.41\\] ml/min, P=0.001), compared to healthy controls; 0.35 \\[0.28- 0.54\\] ml/min, P=0.001).
