Evaluation of the Dental and Periodontal Status of Hemodialysis Subjects and Its Comparison with That of Healthy People

Oral health problems of chronic renal failure patients can compromise systemic health. The purpose of this study was to investigate the dental and periodontal status of patients on regular hemodialysis (HD) maintenance therapy and the effect of duration of HD on oral health. Methods & Materials: In this historical cohort study 65 HD patients and 65 healthy people were collected as case and control groups. Decayed (D), Missed (M) and Filled (F) teeth, DMFT Index, Plaque Index (PI), Gingival Index (GI), and Probing depth (PD) were examined and compared between case and control groups. Also, HD patients were divided into two subgroups based on duration of hemodialysis: 1: three and less than three years and 2: more than three years). In this study all variables were examined and compared between these subgroups. T-test and chi-square and SPSS software were used for statistical analysis.

Except M and DMFT index, significant differences were found in other indices between case and control groups (P<0.05). D, M, F, DMFT values showed no significant differences between the two HD subgroups, whereas, PD, GI and PD values had significant increase in two groups based on the duration of hemodialysis.

The dental and periodontal health is poor in HD patients and periodontal status becomes worse specially during the time of dialysis.
