University of Iowa

What you'll study

The PhD programme is structured around independent, mentored research combined with advanced coursework to build depth in a chosen area of dental science. Students normally select a major area such as oral biology and pathology, craniofacial development, dental biomaterials, tooth regeneration, clinical and translational research, public health dentistry and dental epidemiology, or behavioural and population oral health.

• Core research training: supervised laboratory or clinical research leading to an original dissertation; regular progress meetings with a faculty advisory committee.
• Advanced coursework: research methods and design, biostatistics, molecular and cellular biology techniques, biomaterials science, imaging and histomorphometry, clinical trial design where relevant.
• Elective topics: oral microbiology and immunology, tissue engineering and regenerative medicine, craniofacial genetics, pain science, health services research, leadership and grant-writing workshops.
• Professional development: teaching experience, presentations at national and international conferences, manuscript preparation for peer-reviewed journals, and training in ethics and responsible conduct of research.

Programme length varies with background and research progress; full-time candidates typically undertake several years of coursework and concentrated research culminating in a written dissertation and an oral defence.

Entry requirements

Strong applicants normally hold a relevant postgraduate qualification such as a DDS/DMD, MD, or a master’s degree in a related biomedical or public health field. Candidates without a dental degree but with substantial research experience and appropriate academic preparation may also be considered.

• Academic record: a high-quality undergraduate and, where applicable, postgraduate transcript demonstrating preparation for advanced research.
• Research experience: documented research activity such as a master’s thesis, publications, or laboratory/clinical research work is highly desirable.
• References: strong letters of recommendation from academic or professional referees who can assess research potential.
• Personal statement/Research proposal: a statement outlining research interests and alignment with faculty expertise; some applicants may propose a preliminary research idea.
• English language: proficiency evidence for international applicants (standard tests or approved institutional equivalents) where English is not the first language.

Admission is competitive and typically depends on finding a faculty supervisor with matching research interests. Some applicants may be required to complete prerequisite coursework before fully matriculating.

Career prospects

Graduates of the PhD in Dentistry pursue a range of careers that bridge science and oral healthcare. Common pathways include:

• Academic research and teaching: faculty positions in dental schools and universities leading independent research programmes and instructing clinical and graduate students.
• Clinical-science leadership: roles combining clinical practice with research leadership, such as heads of research in dental clinics or hospitals.
• Industry and biotech: research and development positions in companies focused on dental materials, imaging technologies, pharmaceuticals, and regenerative therapies.
• Public health and policy: roles in government agencies, non-profit organisations, or health systems working on oral health policy, population-level research, and prevention programmes.
• Research administration and funding bodies: positions managing research portfolios, grant review panels, and translational research initiatives.

Why study at University of Iowa

The University of Iowa College of Dentistry and Dental Clinics has a long-established research environment with interdisciplinary links across medicine, engineering, public health and basic sciences. Students benefit from access to well-equipped laboratories, clinical facilities, and core services for imaging, genomics, and biomaterials testing.

• Faculty expertise: a diverse group of investigators whose work spans biomaterials, oral and craniofacial biology, epidemiology, and translational clinical research.
• Collaborative culture: opportunities for cross-college collaborations with the Carver College of Medicine, College of Engineering and the College of Public Health to support translational and multidisciplinary projects.
• Professional development: structured training in grant writing, presentation skills and responsible conduct of research to prepare graduates for competitive research careers.
• Clinical integration: proximity to dental clinics and patient populations enables clinical-translational research and access to real-world datasets and trial populations.

Overall, the programme is designed to develop independent investigators capable of advancing dental science and improving oral health through rigorous research and leadership.
