Social responsibility refers to one's sense of duty to the society in which he or she lives. The Professionalism and Community Service (PACS) dental module at the University of British Columbia is based upon community service-learning and helps dental students to understand the challenges faced by vulnerable segments of the population as they actively reflect on experiences gathered from didactic and experiential activities. This article aims to illustrate the extent to which PACS has fostered awareness of social responsibility through the British Columbia Ministry of Education's Performance Standards Framework for Social Responsibility. Reflections were gathered from students in all four years of the D.M.D. program and were analyzed thematically in three categories of the framework: Contribution to the Classroom and Community, Value of Diversity in the Community, and Exercise of Responsibilities. The constant comparison analysis of the reflective qualitative data revealed that the students directly or indirectly addressed these three categories in their reflections as they synthesized their understanding of community issues and their collaborative roles as socially responsible members of the dental profession. Follow-up studies are needed to explore the impact of community-based dental education upon students' perceptions and understanding of social responsibility and professionalism regarding underserved communities.
