Rheumatoid arthritis (RA) patients exhibit more severe periodontal disease, including bone loss and higher gingival index. Inflammatory markers like ESR and CRP correlate with periodontal disease severity, suggesting a shared inflammatory pathway.
Area of Science:
- Periodontal Medicine
- Immunology
- Rheumatology
Background:
- Periodontal medicine explores the link between oral health and systemic conditions.
- Periodontitis and Rheumatoid Arthritis (RA) may share common immune-inflammatory dysregulation.
Purpose of the Study:
- To investigate the association between periodontal disease and Rheumatoid Arthritis.
- To compare periodontal parameters in RA patients versus controls.
Main Methods:
- 100 patients were divided into 50 RA cases and 50 age/gender-matched controls.
- Periodontal health assessed via plaque index, gingival index, missing teeth, and bone loss.
- RA severity measured by health assessment questionnaires, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR).
Main Results:
- RA patients showed significantly more severe alveolar bone loss and higher gingival index compared to controls.
- Plaque index was similar between groups.
- ESR and CRP levels in RA patients were significantly associated with periodontal disease severity.
Conclusions:
- A significant association exists between Rheumatoid Arthritis and Periodontitis.
- This link may stem from a common underlying inflammatory response deregulation.
