Background: The Oral Health Impact Profile (OHIP) is a well-known method for identifying dimensions in oral health-related quality of life. It measures the individuals' perception of the social impact of oral disorders on their well-being. Objective: To assess the validity and reliability of the oral health-related quality of life questionnaire in tobacco users. Materials and Methods: Data were collected from a sample of 210 patients using a modified (OHIP-21) questionnaire adopted from the OHIP-49 original questionnaire; responses were graded on a 5-point Likert scale. Results: The internal consistency reliability of the questionnaire, as estimated by Cronbach's alpha coefficient (α = 0.75), indicated that the components of the scale measured the same construct. Factor analysis provided a seven-factor model explaining 62.5% of the variance. Physical pain was loaded on the first factor. Conclusion: These preliminary results provided initial supportive evidence of the OHIP-21 reliability and validity in tobacco users. Further studies are needed to confirm this preliminary conclusion.
