The aim of this study was to systematically review the relevant literature on teaching professionalism in dental curricula and report the relevant data from a survey of members of the Association for Dental Education in Europe (ADEE) on the topic. We conducted a systematic review of the literature and a cross-sectional study using an online questionnaire regarding teaching and assessment of professionalism in dental schools, members of the ADEE. The literature review identified 33 articles related to professionalism in dental curricula. The survey sent to the membership of the Association for Dental Education in Europe yielded responses from 27 European dental schools and four schools outside Europe. Various study designs were identified in the review, and the main themes discussed included teaching/pedagogy, ethics/humanities, core domains and assessment of professionalism. Twenty schools reported having specific courses dedicated to professionalism, while the format varied, including entire modules, separate learning outcomes or unit structures. Ethics, communication, law/legal framework/deontology, teamworking and management/leadership were among the common topics taught under the banner of professionalism. Many schools reported increases or no changes in hours, staffing, themes/topics covered and weight in the curriculum for professionalism over the last decade. The paper provides valuable insights into the current state of professionalism education in dental curricula and offers directions for enhancing its effectiveness and relevance in preparing future dental professionals. Collaborative efforts among dental educators and institutions can contribute to the continuous improvement of professionalism education and practice in dentistry.
