Abstract [en]

Objective

The study aims to assess the influence of oral health status and socio-behavioural variables on oral health-related quality of life (OHRQoL) in a sample of Iranian haemodialysis (HD) patients.

Materials and methods

The present case-control study included 512 patients undergoing HD and 255 healthy controls from Iran. A self-reported questionnaire was used to record socio-demographic variables. In addition, laboratory and clinical variables of each patient were extracted from clinical and patient’s electronic records. A closed-ended questionnaire was framed in order to assess oral health knowledge, attitudes and behaviour of each subject. The Short Form Health Survey (SF-36) and Oral Health Impact Profile-14 (OHIP-14) were used respectively to assess general health-related quality of life (GHRQoL) and OHRQoL. All subjects were clinically examined by two trained and experienced dentists for caries by decayed, missing and filled teeth index (DMFT), dental plaque by visible plaque index (VPI), gingival status by Loe and Silness gingival index (GI) and periodontal status by community periodontal index (CPI).

Results

Statistically significant differences were found between HD patients and control subjects for all oral health indices. Patients had significantly (p  < 0.001) higher mean DMFT, VPI and GI values than controls. Periodontal pockets deeper than 4 mm were more frequently diagnosed in HD patients (p < 0.001). HD patients reported significantly poorer GHRQoL and also a higher impact of oral health (i.e. poorer OHRQoL) in comparison with the healthy controls (p < 0.01).

Conclusions

Oral health status, clinical variables, socio-behavioural factors and GHRQoL were significant predictors of OHRQoL in Iranian HD patients.

Clinical relevance

The study findings support the assumption that patient-reported measures can be used to predict treatment need since the objective clinical variables were significantly related to subjective self-reported quality of life in HD patients.
