The aim of this study is (1) to carry out the cross-cultural adaptation and validation of the "Glasgow-UCL Questionnaire" to the Brazilian Portuguese language (2) to assess the impact of dental caries and traumatic dental injuries in childrens' quality of life using the Glasgow-UCL Questionnaire and the impacto on family using the Family Impact Scale (3) to assess the agreement between parents and children concerning the children'quality of life (4) to assess the responsiveness of the "Glasgow-UCL Questionnaire". After the transcultural adaptation of the instrument, validity and reliability will be tested in face-to-face interviews with around 300 children betwen 5 to 6 years old and their respectives parents during dental screening at FOUSP. Internal consistency of the Brazilian "Glasgow-UCL questionnaire" will be assessed using Cronbach's alpha. To assess the impact and responsiveness of the instrument, aorund 210 children will be divided into: 100 and 60 according to the severity of dental caries an traumatic dental injuries, respectively. Another group of 50 children will be aour control group (without caries and trauma). The Glasgow-UCL Questionnaire and da Family Impact Sclae will be apply before and after the dental treatment of children. Effect-size statistics will be calculated by dividing the mean of change scores by the standard deviation of the pretreatment scores, in order to give a dimensionless measure of effect.
