Research Trends in Medical and Dental Education (2015-2024) Based on Author Keywords: Commonalities, Differences, and...

Medical and dental education share the common goal of preparing clinically competent and socially responsible health professionals. Despite this shared goal, the two disciplines have evolved as distinct academic fields, with limited empirical comparisons between them. Understanding their commonalities and differences can foster mutual development and cross-disciplinary collaboration. This study aims to compare research priorities in medical and dental education by analyzing author keywords from representative journals in each field.

A bibliometric analysis was conducted using author keywords from two medical education journals (Advances in Health Sciences Education and BMC Medical Education) and two dental education journals (European Journal of Dental Education and Journal of Dental Education) over a 10-year period (2015-2024). Data were retrieved from the Web of Science database, including only original research articles and review articles. Frequency analysis of the top 10 author keywords was performed in 2-year intervals, and bump charts were created to visualize temporal ranking changes. In addition, co-occurrence network maps were constructed using all keywords appearing 10 or more times over the study period. Data processing and visualization were conducted using VOSviewer and Tableau software.

A total of 9391 articles were analyzed, comprising 6806 articles from medical education journals and 2585 articles from dental education journals. Both fields consistently emphasized "students," "assessment," and "curriculum" as core research topics. However, medical education placed greater emphasis on "postgraduate medical education" and student mental health (e.g., empathy, resilience, and depression), whereas dental education focused more on "educational technology" and clinical skills development (e.g., simulation, virtual reality, and psychomotor skills). The keyword "covid-19" emerged prominently in both fields from 2019 to 2020 onward, reflecting the pandemic's transformative impact on education. "Interprofessional education" appeared as a shared emerging theme, suggesting growing recognition of collaborative practice needs.

This study identifies both foundational commonalities and discipline-specific innovations in medical and dental education research over the past decade. These findings suggest that shared interests and distinctive priorities can lead to meaningful opportunities for collaborative educational development and joint research efforts across health professions education.
