University of California

What you'll study

The programme centres on independent research leading to a doctoral dissertation, supported by structured coursework and mentoring. Typical study areas include oral and craniofacial biology, biomaterials and tissue engineering, periodontal and implant biology, cariology and preventive sciences, craniofacial genetics and developmental biology, dental public health and epidemiology, clinical and translational research methods, and health services research.

• Core coursework – advanced seminars in research design, statistics, molecular and cellular aspects of oral biology, and ethics in human and animal research.
• Laboratory rotations – for students entering from non-dental backgrounds or changing specialisms; provide hands-on experience in different labs and techniques.
• Electives and specialised modules – topics such as biomaterials testing, imaging and microscopy, regenerative medicine, oral microbiome, clinical trial design, and dental informatics.
• Research milestones – qualifying/qualitative exams, a research proposal or candidacy examination, regular progress reviews, and a written dissertation followed by an oral defence.
• Teaching and professional development – opportunities to teach undergraduate or postgraduate courses, present at conferences, and undertake training in grant writing, leadership and research translation.

Entry requirements

Applicants are normally expected to hold a relevant graduate degree such as a DDS/DMD, BDS with a subsequent research master’s, MD, or a MSc/PhD in a closely related biomedical or public health field. Strong applicants demonstrate previous research experience, a clear research statement, and academic references from supervisors. Evidence of laboratory skills or clinical research experience is advantageous.

• Academic transcripts – a record of strong performance in prior degrees.
• Research experience – publications, conference presentations or documented lab/clinical research involvement.
• References – at least two academic referees who can comment on research potential.
• English language proficiency – required where applicants’ prior education was not in English (standard recognised tests accepted).
• Additional materials – a research proposal or statement of research interests and a CV; some campuses or research groups may request an interview.

Career prospects

Graduates of a dentistry PhD typically pursue careers that combine scientific research with leadership or teaching. Common pathways include academic positions (tenure-track faculty, research scientist), roles in dental and biomedical industry (R&D, product development, regulatory science), positions within government or public health bodies (policy, surveillance, programme evaluation), and leadership roles in clinical research centres or teaching hospitals. The degree also prepares dentists for advanced translational research careers bridging bench science and patient care.
