Abstract

BACKGROUND AND OBJECTVE: Chronic inflammatory diseases have been investigated as a possible source of inflammation in chronic kidney disease patients; however, there is a shortage of information about the prevalence of periodontitis in such individuals. Therefore, the aim of this cross-sectional study was to determine the extent and severity of periodontitis in chronic kidney disease patients undergoing the following three different treatment modalities: predialysis; continuous ambulatory peritoneal dialysis (CAPD); and hemodialysis (HD); and to compare the findings with those from systemically healthy individuals.

MATERIAL AND METHODS:

Forty CAPD patients (mean age 52±12 years), 40 HD patients (mean age 50±10 years), 51 predialysis patients (mean age 54±11 years) and 67 healthy individuals (mean age 50±7 years) were examined. The periodontal examination included probing pocket depth, clinical attachment loss, bleeding on probing and presence of plaque. Patients with at least four sites with clinical attachment loss ≥6 mm were considered to have severe chronic periodontitis, and those with at least 30% of sites with clinical attachment loss ≥4 mm were considered to have generalized chronic periodontitis.

RESULTS:

Predialysis and HD patients had significantly more sites with clinical attachment loss ≥6 mm than healthy individuals. The CAPD patients had similar periodontal condition to healthy subjects. There were significantly more cases of severe chronic periodontitis in predialysis and HD patients.

CONCLUSION:

Predialysis and HD are associated with a higher prevalence of severe periodontitis compared with healthy individuals and CAPD patients.
