This study aimed to test Turkish validity and reliability of the Oral Health Impact on Daily Life Questionnaire (OHIDL) in adult endodontic patients.

The questionnaire was translated and adapted into Turkish. Two hundred twenty-two participants aged 18 years and over without systemic disease were included. The reliability was examined by internal consistency and test-retest reliability. The construct and criterion validity were examined by evaluating the correlation of each question with the domains, the correlation of the domains with the global questions, and the correlation of Turkish-OHIDL with the Turkish version of the Oral Health Impact Scale (OHIP-14-TR). Statistical analysis was performed with SPSS 21.0 (IBM Corp, Armonk, NY, USA). P <0.05 was considered statistically significant.
