Summary Background/Aim: The aim of this study was to assess of the internal coherence of Bosnian translated version of the Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT-B&H), and evaluated the validity of this version. Material and Methods: OHIP-EDENT-B&H questionnaires were completed by 117 edentulous patients and specialists of prosthodontics in health institutions of central Bosnia. Results: Test-retesting analysis showed strong correlations, r ranging from 0.46 to 0.58, respecting complete dentures, with Kappa= 0.68, that indicated reliability of the questionnaire. The lowest reliability was obtained for Psychological disability (n= 117, α= 0.636) and the highest was obtained for Social disability (α= 0.859). The reliability of the summary scores for OHIP-EDENT-B&H was good (α= 0.907). Content validity for the test group-retest group did not expose significant differences between the groups tested. Conclusions: The OHIPEDENT-B&H instrument for verifying of oral-health–related quality of life in edentulous patients demonstrated good reliability and validity in Bosnian patients.
