Influência do tratamento periodontal na artrite reumatoide: revisão sistemática e metanálise

Abstract

ObjectiveTo evaluate the influence of periodontal treatment on rheumatoid arthritis activity. MethodsMEDLINE/PUBMED, The Cochrane Library, Clinical Trials, SciELO and LILACS were searched for studies published until December 2014. Included articles were: prospective studies; including patients older than 18 years, diagnosed with periodontitis and rheumatoid arthritis submitted to non‐surgical periodontal treatment; with a control group receiving no periodontal treatment; with outcomes including at least one marker of rheumatoid arthritis activity. Methodological quality of the studies was assessed using PEDro scale. Quantitative data were pooled in statistical meta‐analysis using Review Manager 5. ResultsFour articles were included. Non‐surgical periodontal treatment was associated with a significant reduction of DAS28 (OR: −1.18; 95% CI: −1.43, −0.93; p <0.00001). Erythrocyte sedimentation rate, C‐reactive protein, patient's assessment of rheumatoid activity using visual analogical scale, tender and swollen joint counts showed a trend towards reduction (not statistically significant). ConclusionsThe reduction of DAS 28 in patients with rheumatoid arthritis after periodontal treatment suggests that the improvement of periodontal condition is beneficial to these patients. Further randomized controlled clinical trials are necessary to confirm this finding.
