Optimizing Research Education in U.S. Military Postgraduate Dental Residency Programs

Introduction Three branches of the United States Armed Forces operate independent postgraduate dental schools under the Postgraduate Dental College within the Uniformed Services University of the Health Sciences, graduating over 75 dental specialists annually across 19 training sites. Although the Commission on Dental Accreditation (CODA) mandates independent research for residents, it provides minimal guidance on curriculum development, leading to variability across Army, Navy, and Air Force programs. This inconsistency highlights the need for a standardized research curriculum to ensure military dentists are prepared for evidence-based practice and to maintain excellence in patient care. Materials and Methods This qualitative study evaluated research curricula in U.S. military postgraduate dental residency programs. Eleven participants, including 6 research faculty and 5 recent graduates from Army, Navy, and Air Force programs, were selected through purposive sampling. Data were collected via semi-structured interviews and syllabus analysis. Using Kern's curriculum development framework and Braun and Clarke's thematic analysis, 3 authors independently coded transcripts, identified patterns, and reached consensus on themes. Results Research curricula across the Department of Defense postgraduate dental residency programs shared common goals, content, and teaching methods while adapting to local needs. Four major themes emerged: critical thinking skills, limited research time, the research educational mission, and modes of instruction. Challenges such as faculty turnover, instructional variability, and poor time management impacted effectiveness. Improved time management and refined educational strategies could enhance research training outcomes. Conclusion Department of Defense postgraduate dental residency programs offer comparable research curricula with unique strengths. Critical thinking development should be central to an optimal research curriculum. Effective time management and self-directed learning are also crucial for balancing research with clinical responsibilities.
