Periodontal disease elevates chronic inflammation markers like IL-6 and hs-CRP in healthy individuals. Non-surgical therapy effectively reduced these inflammatory markers after three months.

Area of Science:

  • Oral Health
  • Immunology
  • Systemic Inflammation

Background:

  • Periodontal disease is linked to systemic inflammation, but its independent effect on inflammatory markers is unclear.
  • Few studies examine periodontal disease's impact on chronic inflammation markers in otherwise healthy, non-smoking individuals.

Purpose of the Study:

  • To compare chronic inflammation markers in patients with periodontal disease versus controls.
  • To assess the effect of non-surgical periodontal therapy on these markers.

Main Methods:

  • Analyzed plasma and serum from 20 controls and 25 non-smoking patients with periodontal disease.
  • Measured inflammatory markers including IL-6 and hs-CRP before and 3 months after therapy.
  • Assessed clinical periodontal parameters and hematologic markers.

Induction of Periodontitis via a Combination of Ligature and Lipopolysaccharide Injection in a Rat Model

Published on: February 17, 2023

Main Results:

  • Patients with periodontal disease showed higher baseline IL-6 levels compared to controls.
  • Non-surgical therapy significantly improved clinical periodontal parameters.
  • Circulating IL-6 and hs-CRP levels decreased 3 months post-therapy.

Conclusions:

  • Periodontal disease is associated with elevated IL-6 and hs-CRP in otherwise healthy individuals.
  • Non-surgical periodontal therapy reduces these systemic inflammatory markers.
  • Other tested markers (CD40 ligand, MCP-1, sP-selectin, sVCAM-1, sICAM-1) did not show significant changes.
