Objectives: This study assessed the relationship of periodontal disease with rheumatoid (RA)
Background: Rheumatoid arthritis is the most prevalent chronic inflammatory disease of the joints. It is correlated with periodontal disease due to similar factors that exist in both diseases.
PD (4.17mm vs. 3.6mm), CAL (4.89mm vs. 4.18mm), percentage of sites with PD>4mm (58.83% vs. 44.33%), percentage of sites with CAL>3mm (74.13% vs. 64.4%), percentage of sites with bleeding on probing (9.67% vs. 6.87%) and PI index (85.73% vs. 80.63%) were significantly higher in RA patients than controls. In this group, significant direct correlations were found between serologic findings, disease severity and number of painful/inflamed joints with periodontal factors.
Material/Methods: In this case-control study, 30 RA and 30 JIA patients along with their matched controls were selected. Periodontal parameters including pocket depth (PD), clinical attachment level (CAL), Plaque index (PI) and bleeding on probing (BOP) were determined in cases and controls. ESR, number of painful/inflamed joints and arthritis severity were evaluated. Relationships of periodontal parameters with RA findings were statistically assessed by Mann Whitney U, Student t-test and Spearman and Pearson’s correlation coefficients with an alpha error less than 0.05.
Severity of periodontal disease increases in patients with rheumatoid arthritis. Thus, periodontal disease can be more severe in RA.
Points for discussion: The present study is one of the few studies which evaluate the periodontal condition in both RA and JIA patients and as far as we know is the only one in Iran evaluating this relation in JIA patients
