There has been a growing interest among dental educators regarding the opportunities offered by community-based dental education as a means to allow dental students to assume their role as health professionals in the real world. Although several dental schools have integrated community-based education into their curricula, most have not engaged their students in the development of competencies to address dental health needs at the community level. The purpose of this article is to discuss the teaching-learning experiences in dental public health at the undergraduate level in the Faculty of Stomatology at the Universidad Peruana Cayetano Heredia (FS-UPCH) in Lima, Peru. The teaching-learning activities in dental public health at the FS-UPCH consist of two well-defined stages: experiences in low-income urban communities and experiences in low-income rural communities. Both stages have been designed to make it possible for students to acquire competency in addressing oral health needs at the community level as well as to enlarge and deepen their knowledge about the social and health situation in Peru. In community-based dental education, students are not only placed in community settings to treat individual patients, but also challenged to consider dental public health issues, including the administrative aspects of dental services.
