Development of an Interdisciplinary Course in Information Resources and Evidence-Based Dentistry

The capacity to locate, access, and appraise information is an important skill required for Success in dental school and beyond. An interdisciplinary Course was implemented to teach first-year dental students at the University of Texas Health Science Center at Houston Dental Branch about evidence-based dentistry, search strategies, critical appraisal of the literature, and dental informatics. Students learned to develop a clinical question, conduct a search to find answers to that question, and critically appraise one of the retrieved resources. Over a period of four years, a total of 259 dental students completed a questionnaire that requested their assessment of this course. Seventy-five percent of the respondents agreed or strongly agreed that they learned to effectively search databases such as the Cochrane Collaboration and PubMed and to critically appraise websites and journal articles and that the information on evidence-based dentistry and critical thinking skills was valuable. In response to open-ended questions, approximately 35 percent of the respondents mentioned the importance of learning to search PubMed and Cochrane databases. Approximately 20 percent of the respondents felt the course did not contain new information. These results indicated the effectiveness of the course in familiarizing the students with the capacity of online resources to help them locate, access, and appraise information pertinent to oral health issues and the practice of dentistry. A future goal is to integrate information and skills associated with evidence-based practice into other courses in the dental curriculum.
