“Oral Health-related Quality of Life and Periodontal Status in Chronic Kidney Disease Patients: A Cross Sectional Study”

Abstract Background: Oral health-related quality of life includes the effect of factors such as oral health and oral function on people’s lifestyles. Chronic kidney disease is caused by the deterioration of kidney structures, decreasing their function. CKD causes some oral problems, and these problems could affect people’s quality of life. This study was conducted to determine OHRQoL and periodontal health status in CKD patients. Methods: One hundred and four CKD patients participated in the study. Their OHRQoL was assessed by Oral Health Impact Profile-14 (OHIP-14), and their periodontal status was assessed by the community periodontal index of treatment needs (CPITN). The stage of the disease was measured by BUN and creatinine. We used t-test, ANOVA, and Pearson’s and Spearman’s correlation tests for statistical analyses. Results: The most frequent CKD stage was 5. The average total score of OHIP-14 in these patients was 14.82 (±4.86). The most frequent CPITN score was 2 (calculus). CPITN had a direct relationship with the total score of OHRQOL (P=0.004) and its physical domains (P<0.05). Conclusion: There was a significant relationship between periodontal status and OHRQoL in CKD patients. The quality of life in this group of patients might be improved by providing their periodontal treatment needs.
