Aim ― This study was designed to analyze the citations of medical education to measure primarily the research trend of Problem-based learning in medical education and to compare them in the fields of dentistry with medicine, nursing and pharmacology. Material and Methods ― This study was a descriptive study using scientometrics and systematic review of citations. Electronic data bases Web of Science and PubMed were searched during the 2003-2013 for related article were extracted and critically appraised based on the level of education visualize the application of Problem-based learning in dentistry and pharmacology, nursing and medicine. We analyzed data using SPSS 18. A p-value less than 0.05 were considered significant. Results ― Dentistry 64(8%) was ranked three followed by nursing. The dentistry was ranked in the third on sharing articles of implementing Problem based Learning in education.
