Periodontal Inflammation in Patients with Migraine


Periodontal inflammation is associated with increased circulating levels of calcitonin gene-related peptide (CGRP) in patients with chronic migraine, a new study found. The cohort included 102 chronic migraineurs and 77 age- and sex-matched individuals free of headache/migraine. Full-mouth periodontal parameters were recorded and the periodontal inflamed surface area (PISA) was calculated to quantify the periodontal inflammatory status for each participant. Researchers found:

  • In the chronic migraine group, patients with periodontitis had greater levels of serum CGRP and IL-6, while nonsignificant differences were observed with IL-10 concentrations vs those without periodontitis.
  • PISA was independently associated with CGRP in patients with chronic migraine.
