Abstract :Aim: Oral health has an important role in the general health. It was aimed to evaluate the validity and reliability of Turkish version of Oral Health Impact on Daily Life Questionnaire (OHIDL) in adult endodontic patients. Material and Method: The OHIDL was translated and adapted into Turkish. The Turkish version of OHIDL (Turkish-OHIDL) and Turkish version of the Oral Health Impact Scale (OHIP-14-TR) were applied to 222 adult endodontic patients (18 years and older) with no systemic disease. The reliability of the questionnaire was examined by test-retest reliability and internal consistency. The validity was evaluated by the correlations between domains and global questions, and between Turkish-OHIDL and OHIP-14-TR. The structure of the hypothesized domains of the OHIDL was analyzed by confirmatory factor analysis (CFA). Results: The Turkish-OHIDL exhibited high internal consistency (Cronbach\'s alpha=0.89) and test-retest reliability (Intraclass Correlation Coefficient=0.86). There was a significant correlation between Turkish-OHIDL and OHIP-14-TR among all domains. There was a very strong correlation in terms of total score as well (rs: 0.78, p<0.001). The total OHIDL score showed the highest correlation with the global question regarding the overall impact of oral health on daily life (G3/rs:0.54), indicating a moderate correlation. Five factors containing more than one item, were statistically verified as acceptable fit using CFA. Conclusion: Turkish-OHIDL has been proven as a valid and reliable tool for the measurement of oral health-related quality of life.
