RESUMO

INTRODUCTION: Periodontal disease is an infectious disease associated to a chronic inflammation of dental tissues. Inflammatory mediators and cytokines determine the course of rheumatic diseases. The aim of this study is to evaluate if periodontal disease (PD) treatment influences systemic lupus erythematosus (SLE) activity. METHODS: Forty-two SLE patients (ACR, 1997) were evaluated and consecutively randomized in two groups. Exclusion criteria were SLEDAI <2 and/or bleeding gingival index (BGI) of zero, resulting in TREATED group with 19 patients and CONTROL with 17 patients. All SLE patients were under IV cyclophosphamide therapy. Both groups were matched for age, gender, and race. Erythrocyte sedimentation rate (ESR), C- reactive protein (CRP) and SLEDAI were determined. Periodontal disease graduation was defined according to probing depth (PD), bleeding gingival index (BGI) and probing attachment level (PAL). Odontological treatment focused a complete mouth desinfection. TREATED group have odontologial treatment immediately at entry and evaluated after three months. CONTROL started odontological treatment after 3 months of observation period. At the end, all SLE patients with SLEDAI ³ 2 and/or BGI >zero, entered in the TREATED group (n=32). These patients were evaluated 3 months after the end of odontological treatment. RESULTS: At entry, both groups had similar BGI (40.75 ± 30.98 vs. 40.72 ± 36.19%, p=0.89), PD (1.73 ± 1.80 vs. 1.48 ± 0.59mm, p=0.80), and PAL (2.47 ± 1.9 vs. 1.91 ± 1.34mm, p=0.18) and also for ESR (20.69 ± 23.88 vs. 23.41 ± 21.92 mm/h, p=0.80), CRP (4.7 ± 4.61 vs. 4.21 ± 5.86mg/dl, p=0.34) and SLEDAI (5.94 ± 4.24 vs. 6.29 ± 4.35, p=0.73). Efficacy of odontological treatment was identified in the reduction of all indexes of TREATED group: BGI (40.75 ± 30.98 vs. 15.19 ± 17.22%, p<0.01), PD (1.73 ± 1.80 vs. 1.10 ± 0.29 mm, p<0.01) and PAL (2.47 ± 1.96 vs. 1.68 ± 0.90 mm, p<0.01). ESR and CRP did not alter during treatment in both groups. TREATED group had a significant reduction in SLEDAI (5.94 ± 4.24 vs. 3.38 ± 3.30, p=0.04) after odontological treatment whereas CONTROL had similar odontological and clinical parameters during the 3 months of observation. CONCLUSION: SLE patients after odontological treatment had a significant reduction of SLEDAI with a better control of the inflammation of the disease.
