The dilemma of different dental degrees: DDS and DMD

Although the Doctor of Dental Surgery (DDS) evolved from the surgical and the Doctor of Medicine in Dentistry (DMD) from the medical (DMD) roots of the dental profession, dental schools in the US currently award both degrees, verified as equivalent by finding no differences between them in standards of admissions, accreditation, or state licensure requirements while continuing to be subjectively perceived as different enough to create professional and public confusion. In contrast, Doctors of Osteopathy (DOs) and Doctors of Medicine (MDs) are both objectively and subjectively perceived as different in philosophy and healthcare training while objectively passing similar examinations to be licensed as physicians. Following from the history of both dental degrees and their implications for training and dental practice, the objective of this manuscript is to update the scientific, socio-political, and professional reasons for awarding only the DMD for future graduates while continuing to recognize the contributions of DDS graduates to oral healthcare. Working with the American Dental Association (ADA), American Dental Education Association (ADEA), and dental school librarians, a historical review was undertaken of the establishment of two doctoral degrees for dentists in the United States, including beliefs and attitudes of faculty and local dentists at the times of initiation or change in degrees awarded. Among the current 68 dental schools in the United States, there are approximately equal numbers of DDS- and DMD-granting schools. Except for some Harvard physicians, some of whom practiced dentistry, who wanted dentistry to be a specialty of medicine and the unexpected, serendipitous substitution of "medicine" for "surgery" which could not be translated into required Latin in 1867, all dental schools would have awarded only the DDS degree. Now, with the ongoing reorganization of the healthcare workforce in the United States, a single degree with broader healthcare connotations of the DMD will facilitate the integration of dentistry with overall healthcare, without changing the fundamental oral healthcare responsibilities of both DDS and DMD graduates.
