Why it matters for dental
Dental professionals treating stage III–IV periodontitis should recognize that chronic periodontal inflammation may alter systemic iron metabolism, potentially complicating anemia work-ups; owners and staff should document this link in medical histories to improve interdisciplinary communication.
Key points
- A 2023 systematic review and meta-analysis of 26 studies found patients with chronic periodontitis had significantly lower hemoglobin, red blood cell counts, and packed cell volume than healthy controls.
- Han and colleagues linked elevated IL-6–STAT3–hepcidin activity to lower serum iron and altered hematologic measures in periodontal disease patients.
- A 2025 study of stage III–IV periodontitis patients showed higher hepcidin and ferritin and lower serum iron and transferrin compared with controls; after nonsurgical periodontal therapy, hepcidin and ferritin decreased while serum iron and transferrin rose.
- Greater periodontal severity correlated with larger disruptions in iron metabolism parameters in the 2025 study cohort.
