Chronic  periodontitis (CP) is an infectious inflammatory disease, which can be increased by the systemic inflammatory response in patients with chronic kidney disease (CKD). The aim of this study was to evaluate the prevalence of CP in smokers in the pre-dialysis stages of CKD.

Subjects and Methods: Ninety-four individuals were and divided into two groups; group 1 was composed of smokers with CKD and group 2 was composed of non-smokers with CKD.

Results: The probing depth (PD) was significantly elevated in group 1 than in group 2 (2.28 ± 0.52 mm vs. 1.89 ± 0.47 mm, respectively; P < .001.It was found that CP was more prevalent in group 1, with a total of 41 patients (87%), compared to group 2 in which 33 patients were affected by the disease (70%).

Conclusion: Smoking appears to increase the prevalence of CP in patients with CKD.
