Summary  The aims of this study were to evaluate the reliability and to validate a Brazilian version of Oral Health Impact Profile for assessing edentulous subjects (OHIP‐EDENT), an inventory for measuring oral health‐related quality of life of edentulous subjects. The sample comprised 65 complete denture wearers (23 men, mean age of 69·1 ± 10·3 years). The translated OHIP‐EDENT was applied on two occasions with a washout period of 3 months. Reliability was assessed by an internal consistency analysis and a test‐retest approach. A preliminary validation process was conducted by a qualitative approach/interview. Results of internal consistency showed a Cronbach’s α of 0·86 or 0·90 for the first or second appointment respectively. Through the test‐retest analysis, an intra‐class correlation coefficient of 0·57 was found, and individual answers reflected a broad range of agreement. Interviewed volunteers (n = 6) comprehended most questions well. In conclusion, the Brazilian version of OHIP‐EDENT is adequate for assessing the oral health‐related quality of life for edentulous subjects.
