A total of 342 students from four public schools took part of the study.Overall, 80.7% of the sample reported at least one oral impact in the last three months. Cronbach's alpha was 0.63, the weighted kappa 0.76, and the intraclass correlation coefficient (ICC) 0.79. The index had a significant association with self-reported health measurements (self-rated oral health, satisfaction with oral health, perceived dental treatment needs, self-rated general health; all p < 0.01).It was concluded that the Child-OIDP index is a measure of oral health-related quality of life that can be applied to Brazilian children.The World Health Organization (WHO) defines health as a "state of complete physical, mental and social well-being and not merely the absence of disease or infirmity" [1]. Based on this concept, measuring health should not be confined to the use of exclusively clinical normative indicators. Health-related quality of life (HRQoL) measures are being used nowadays to evaluate dimensions of health, such as psychological and social aspects, that are not assessed by other measures. HRQoL measures can be categorized as: generic or specific. The generic measures are used to evaluate the impact of general health problems on quality of life. The specific measures focus on the repercussions of particular health conditions, health problems or treatments on the quality of life [2].Oral health-related quality of life (OHRQoL) indices have a specific application in the evaluation of the impacts of oral problems on daily activities. These indices are most commonly used for adults or elderly populations. Some authors have adapted and applied instruments developed for adults to children and adolescents [3,4]. However, there is a trend to generate specific indices which cater for the needs of younger populations [5,6]. One of the measures developed specifically for %U http://www.hqlo.com/content/6/1/68
