Graduate Programs of Study

  • Master of Science in oral science
  • Doctor of Philosophy in oral science

Graduate programs in oral science require that students complete courses from a core curriculum and conduct independent research leading to a thesis. The programs prepare graduates for careers in teaching and research.

Students must enroll in a professional certificate program offered by a College of Dentistry department in order to enroll in the Master of Science program in oral science. The following departments offer their certificate students the opportunity to earn graduate degrees in oral science: Endodontics. Prosthodontics, and Operative Dentistry students may earn an M.S. or Ph.D. in oral science; Oral Pathology, Radiology, and Medicine and Periodontics students may earn an M.S. in oral science.

Master of Science

The Master of Science program in oral science requires a minimum of 30 s.h. of graduate credit, including 21 s.h. of course work, 9 s.h. of independent research leading to a thesis, and a final examination. M.S. students must spend at least two years in full-time residence at The University of Iowa.

Students pursuing the M.S. normally must be enrolled in a clinical specialty training program offered by a College of Dentistry department. Students should complete the M.S. and the clinical specialty training program in three years of study.

Doctor of Philosophy

The Doctor of Philosophy program in oral science requires a minimum of 72 s.h. of graduate credit, including advanced course work and original research that culminates in the successful defense of a dissertation. Students must pass a comprehensive examination, prepare and gain approval of a research project, and complete and successfully defend a dissertation that describes the results of their research. Completion of the program usually requires at least four years of full-time study.

Admission

Applicants to the M.S. and Ph.D. programs must meet the admission requirements of the Graduate College. Applicants whose first language is not English must score at least 550 (paper-based) or at least 79 (Internet-based) on the Test of English as a Foreign Language (TOEFL); they also may be asked to take the Test of Spoken English.

Programs normally begin July 1 each year.

Applicants to the Ph.D. program are asked to submit a statement describing past research experience and current research interests, and stating how completion of the Ph.D. program fits their career goals.

A personal interview may be requested for either program.
