Background and Aim: Given the current need for studies evaluating oral health related quality of life among the Iranian children, this study was designed to test the validity and reliability of a Persian version of Child-OIDP index and also evaluate the prevalence and impact of oral disorders on the quality of life of 11-14-year-old Iranian children.

Materials & Methods: In this cross-sectional study, after translation of Child-OIDP instrument into Persian language, the psychometric properties of this index were evaluated in terms of face, content and construct validity. In addition, the internal and test-retest reliability were evaluated. A sample of 384 Iranian children aged 11-14-years old completed the instrument via a face-to-face interview. Each interview was followed by a clinical examination as well as completion of a self-administered questionnaire providing the information on demographic and oral health behaviors.

Results: The Persian version of Child-OIDP demonstrated excellent validity and reliability. The index showed significant associations between perceived oral treatment needs and perceived satisfaction regarding their oral cavity (P<0.001). ICC was 0.784, and Cronbach’s alpha was 0.59. About 54% of children reported dental disorders over the past 3 months that impacted on daily performances, according to Child-OIDP index. The most prevalent affected activities were eating and oral hygiene performance. The most prevalent oral disorder leading to impact were sensitivity tooth and gingival bleeding.

Conclusion: Based on the results of this study, it can be concluded that the Persian version of Child-OIDP index is a valid and reliable instrument for evaluation of oral health-related quality of life as applied to Iranian children. The prevalence of oral impacts was moderate. The pattern of impacts differed according to the type of self-perceived oral problem.
