Abstract

Objectives: OHIP-EDENT is a shortened version of the Oral Health Impact Profile instrument The purpose of this study was to develop and evaluate the Turkish version of it (OHIP-EDENT-TR) for the elderly population in Turkey.

Materials and Methods: A total of 120 edentulous patients (72 males, 48 females; mean age 65.59 ± 7.61 years) who had complete prostheses were included in the study. The patients completed the OHIP-EDENT-TR, which was translated during this study, and a visual analogue scale (100 mm) twice at an interval of 3 months. Cronbach’s alpha was used to measure the internal consistency of the summary scores for the OHIP-EDENT-TR. The interclass correlation coefficient and 95% confidence interval of the summary scores for the OHIP-EDENT-TR and its subscales were calculated.

Results: The lowest and highest reliabilities were obtained for questions 7 (n = 120, α = 0.888) and 2 (α = 0.931), respectively. The reliability of the summary scores for the OHIP-EDENT-TR was good (α = 0.903). There was a significant relationship between the OHIP-EDENT-TR scale and visual analogue scale scores (p < 0.001). These values were indicative of fair-to-excellent convergent validity.

Conclusions: The Turkish version of OHIP EDENT (OHIP-EDENT-TR) is a reliable, valid and applicable scale for evaluating oral health related quality of life in the Turkish elderly patients.
