Periodontal disease as a predictor of chronic kidney disease (CKD) stage in older adults.

Objective: The aim of this study was to evaluate periodontal disease as a predictor of chronic kidney disease (CKD) stage in older adults.

Methods: A total of 1159 adults aged 65 to 80 years and diagnosed with periodontal disease and CKD (stages 1, 2, and 3) were randomly selected for a cross-sectional study. Periodontal status was assessed using the Community Periodontal Index of Treatment Needs (CPITN) and CKD was staged using the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) guidelines.
