Reliability of Turkish versions of two different oral health indexes for edentulous geriatric patients: A pilot study

Abstract

Aim: This study aimed to evaluate the Turkish version of the Geriatric Oral Health Assessment Index (GOHAI-TR) and OralHealth Impact Profile for Edentulous (OHIP-EDENT-TR) in edentulous geriatric patients using a total prosthesis.Material and Methods: Twelve items in GOHAI and 19 items in OHIP-EDENT were translated into Turkish using the backtranslationtechnique. A total of 32 complete edentulous geriatric participants answered the GOHAI-TR and OHIP-EDENT-TRindexes twice at two different times (first day and second week). The data obtained from both applications were used forreliability and test-retest analysis. Reliability was analyzed with Cronbach's alpha (?) and test–retest analyses were conductedusing statistical software.Results: The mean item score of GOHAI-TR was found to be higher, especially in terms of physical function negativelyaffecting the quality of life. Cronbach's ? value of GOHAI-TR was found to be 0.897 and it any of the index items did not needto be removed. Similarly, the OHIP-EDENT-TR index showed that the most serious problems among participants were related topsychological discomfort, psychological and social disability, and also handicap. Cronbach's ? value of OHIP-EDENT-TR wasfound to be 0.947 and it was determined that no item was required to be removed from the questionnaire.Conclusion: The GOHAI-TR and OHIP-EDENT-TR indexes can be considered scales with excellent reliability and homogeneityfor edentulous patients. Further studies are needed to elucidate different factors such as bone resorption degrees and period ofedentulousness that may affect oral health and satisfaction in edentulous geriatric individuals.
