It's important to say that it was countless reflections that led to this social desire to change dental care in the prison system becoming this book. As such, I cannot fail to highlight the importance and commitment of each author in reflecting, theorising and analysing the reality of our research locations. In view of this, it is hoped that this book will be a starting point for reflection on dental care in the prison system of Joao Pessoa - PB, as well as a source for the development of new research of the most diverse kinds, because only in this way will we have the realisation of universal human rights.
