ABSTRACT
Adolescent's oral health status is able to determine not only their general health status, but also the quality of health in their adult life. Therefore, a poor oral health during adolescence might also have a negative impact on the long-term quality of life. The social determinants of health, which consist of the social conditions in which they live and develop their lives, are relevant ele-ments in the families of these adolescents and have an impact on their health. The aim of this study is to evaluate the caries history and associated factors in adolescents residing in SENAME centers in Province of Concepción. No statistically significant differences were observed among the number of decayed, missing and filled teeth by sex, by presence of psychiatric background or by admission cause. This study analyzed a sample population with multiple risk factors, which make it more susceptible of developing alterations in oral health. The great majority of the results of our investigation proved that there weren't variables significantly connected or associated with caries history.
