“…The purpose of this article is to provide an overview of two major teaching paradigms currently in use in dental education: case-based learning (CBL) and problem-based learning (PBL) and to situate each in adult learning theory. As an aide to broadening understanding of these approaches in order to support their expansion in dental education, the article also aims to draw distinctions between CBL and PBL and to argue for increased use of multidisciplinary teaching in dentistry. We recommend CBL when implementing curriculum reform incorporating an active learning methodology.” (Nadershahi)
