ResumoThe aim of this study was to investigate whether experimental periodontitis cause changes to the renal tissues and imbalance in oxidative stress in kidneys.Twenty-two female Wistar rats were separated into two groups: control and periodontitis. We assessed the following parameters: gingival bleeding index (GBI), tooth mobility, gum malondialdehyde (MDA), myeloperoxidase (MPO) activity, probing pocket depth (PPD), alveolar bone loss (ABL) for periodontal tissues; histomorphometric measures associated with renal corpuscle and histopathological aspects (evaluation of brush border) for kidneys; as also blood and urine biomarkers. Finally, we evaluated renal oxidative stress through glutathione (GSH) and MDA respectively.With regard to renal histomorphometry, significant differences were observed in all parameters assessed. In relation periodic acid Schiff (PAS) staining, disruption was observed of brush border in the periodontitis group in the renal tubules in comparison with the control group. The periodontitis group presented significantly higher MDA and lower GSH concentrations in the kidneys compared with animals without periodontitis.The induced periodontitis caused histomorphometric changes in renal tissues as well as disruption of the brush border in renal tubules, alterations associated with increase in oxidative stress in kidneys. However, these alterations were not sufficient to cause differences in the renal function markers.
