The aim of this study was to evaluate the effect of periodontal treatment on the progression of renal dysfunction and metabolic markers (albumin, cholesterol and triglycerids) in patients with chronic kidney disease (CKD) and chronic periodontitis. Fifty seven patients with CKD at pre-dyalisis phase and chronic periodontitis were evaluated 90 days, while 29 patients were evaluated 180 days after periodontal therapy. Periodontal clinical parameters included plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD) and probing attachment level (PAL). The laboratory exams glomerular filtration rate (GFR) and creatinin (mg/dl), triglycerids (mg/dl), total cholesterol (mg/dl) and albumin (g/dl) levels were evaluated at baseline and 90 and 180 days after periodontal therapy. GFR was evaluated with the Modification of Diet in Renal Disease (MDRD) equation. Ninety days after periodontal therapy (n=57), all periodontal clinical parameters significantly improved (p<0.05). There was a significant improvement on the median values (interquartile range) of GFR from 36.2 (24) ml/min on baseline to 37.5 (24) ml/min on day 90. After 180 days of the periodontal therapy (n=29), there was a significant improvement of the periodontal clinical parameters (p<0.05). The median (interquartile range) of the GFR was 36.2 (27.3) on baseline and 39.4 (27.9) ml/min on day 180 (p<0.05). No significant differences were observed at the median values of creatinin, albumin, total cholesterol and triglycerids comparing baseline, 90 and 180 days after periodontal treatment. In conclusion, periodontal clinical parameters and GFR improved significantly 90 and 180 days after periodontal treatment. Although the progression of the renal dysfunction may be related to many factors, periodontal treatment may be beneficial to the course of CKD.
