The overall objective of this research project is to evaluate, by two longitudinal studies, variables that impact on school performance and oral health related quality of life (OHRQoL) in children and adolescents. Study 1: It will be held in Piracicaba / SP to evaluate the impact of a program of dental care on the school performance of children 8-10 years. Is selected a random sample comprising at least 30% (n = 360) of children participating project "Always Smiling", divided into two matched groups: (1) need treatment, which passed the curative treatment (2) not requiring treatment for dental caries. The school performance or the periods prior and subsequent to the completion of dental treatment will be achieved in schools, by grade of schoolchildren. Study 2: It will be held in Juiz de Fora / MG through the reevaluation of students who participated in an epidemiological survey previously conducted in 2009, when adolescents were aged 12 years.
