Background: The metabolic syndrome and periodontitis coincide with systemic inflammation

and glucose tolerance disorder, which indicate the common pathophysiologic pathway of these

diseases. The main goal of this study was to determine the effects of the metabolic syndrome on

the periodontal indices of hemodialysis (HD) patient.

Materials and Methods: In this descriptive‑analytical study, 75 persons were selected by the simple

method, 50 of them were HD patients, and 25 of them were healthy people. They were divided

into three groups each of which included 25 persons. The periodontal conditions of the selected

persons were determined by radiography, gingival index, probing pocket depth, and bleeding index.

Then, the periodontal indices of the patients suffering from metabolic syndrome and the persons

not affected by metabolic syndrome were compared. At the end, the data were analyzed by SPSS

software (version 20) using Mann–Whitney and Kruskal–Wallis tests at the meaningful level of

α = 0.05. Since the condition of the unilateral variance test could not be provided for this study,

the Kruskal–Wallis test was used. To complete the test, the Mann–Whitney test was used in the

binary form among the groups being studied.

Results: The obtained results showed a meaningful difference among the groups under

study (P < 0.001). The results of the test showed a meaningful difference among the obtained indices

of the groups being studied in the binary form (P < 0.001) too.

Conclusion: The results of the present study revealed when the severity of chronic systemic

disease increased the health of the periodontal tissues would decrease.

Key Words: Hemodialysis, patients, metabolic syndrome, periodontal indices
