Oral status, quality of life, and anxiety and depression in hemodialysis patients and the effect of the duration of treatment by dialysis on these variables

Abstract

This study aimed is to evaluate the oral health status, quality of life, anxiety and depression among hemodialysis patients and to analyze the effect of the duration of dialysis on these variables. 120 patients on hemodialysis and 120 control subjects underwent oral examination, periodontal evaluation, xerostomia study using a Visual Analogue Scale (VAS), sialometry evaluation; quality of life (QOL) using the OHIP-14 questionnaire and anxiety/depression. Bleeding index, CPTIN, clinical attachment level, and probing depth were significantly higher in the hemodialysis group than the control group (p < 0.001). VAS scores were higher in patients on hemodialysis with significant differences in 6 of the 8 domains (p ≤ 0.05). Unstimulated whole saliva was significantly lower in hemodialysis patients than control subjects (p < 0.001). OHIP-14 scores showed significantly poorer QOL in patients on hemodialysis than control subjects (p = 0.042). Hemodialysis patients presented greater depression and anxiety than control (p < 0.001). Periodontal health was worse among the patients who had been in treatment >10 years, xerostomia and sialorrea was worse in patients treated for 5–9.9, and >10 years, QOL was worse in patients who had spent <1 year; depression and anxiety was greater among those treated for 1–2.9 years. In conclusion, Oral health, QOL, anxiety and depression are worse in patients on hemodialysis, and oral health deteriorates as the time spent in dialysis lengthens, but patients in treatment for <3 years presented the poorest QOL and the greatest anxiety and depression.
