N2  - Emerging hypotheses suggest a potential connection between periodontitis and COVID-19, yet concrete evidence is scarce. This study aimed to explore whether periodontitis is linked to the severity of COVID-19. In this cross-sectional study, COVID-19 patients were classified into mild, moderate, and severe groups based on high-resolution chest CT (HRCT) severity scores. Comprehensive periodontal assessments—including plaque index (PI), bleeding on probing (BOP), probing depth (PD), gingival recession (REC), clinical attachment loss (CAL), and counts of mobile and teeth lost due to periodontitis—were recorded for each patient. Data were analyzed using appropriate statistical methods. Among the 294 participants, 149 (50.7%) presented with periodontitis, with the highest occurrence (87.5%) in the severe COVID-19 group. Advanced stages of periodontitis (stage III–IV) were significantly more prevalent among patients with severe COVID-19 than in those with milder forms. HRCT severity scores demonstrated a moderate positive association with worsened periodontal measures. Patients with periodontitis had a 2.81 times greater likelihood of developing severe COVID-19, indicating a significant association between periodontal disease and increased COVID-19 severity.
