The OHIP-EDENT B&H Questionnaire: Translation and Psychometric Properties in Treatment of Acrylic Complete Denture Wearers

Abstract Objectives. The OHIP-EDENT (the OHIP-EDENT B&H) translated from the original English language version was assessed in complete denture wearers before and after new denture manufacture and adjustments.Materials and Methods. A total of 117 acrylic complete denture wearers participated. The convergent validity was assessed by calculating point bi-serial correlations between the OHIP-EDENT Summary scores and the quality old dentures. Responsiveness was assessed by comparison of Summary score before (old dentures) and after adjustments of new dentures. Results. Cronbach alpha coefficient was 0.80 in the patients with their old dentures and 0.76 in same patients after receiving new dentures and all adjustments provided. Convergent validity coefficients varied between 0.491 and 0.548. Responsiveness was confirmed by significantly lower scores of the OHIP-EDENT B&H after new denture delivery and adjustments, both for Summary scores (p=0.027), as well as for the domains of functional limitation (p=0.02), psychological discomfort (p=0.01), physical pain (p=0.003), and handicap (p=0.04). Conclusions. The translated version of the OHIP-EDENT B&H showed good psychometric properties. Clinical Relevance. Clinical significance of the application of the OHIP-EDENT B&H questionnaire is in the reflection of the achieved success in the therapy by acrylic complete dentures after corrections of teeth and denture surfaces at recalls.
