Oral and maxillofacial radiology (OMFR), also known as dental and maxillofacial radiology (DMFR), is the specialty of dentistry concerned with performance and interpretation of diagnostic imaging used for examining the craniofacial, dental and adjacent structures.[1][2]

Oral and maxillofacial imaging includes cone beam CT, multislice CT, MRI, PET, ultrasound, panoramic radiography, cephalometric imaging, intra-oral imaging (e.g. bitewing, peri-apical and occlusal radiographs) in addition to special tests like sialographs. Other modalities, including optical coherence tomography are also under development for dental imaging.[3][4]


United States[edit]

OMFR or DMFR is one of nine dental specialties recognized by the American Dental Association.[1][5]

To become an Oral and Maxillofacial Radiologist (OMFR) one must first complete a dental degree and then apply for and complete a postgraduate course of training (usually between 2–4 years in length).[6] Training includes all aspects of radiation physics, radiation biology, radiation safety, radiologic technique, the patho-physiology of disease and interpretation of diagnostic images.

The Commission on Dental Accreditation (CODA) accredited programs are a minimum of two years in length.[7] Several CODA accredited programs in OMFR require the resident to complete a graduate degree (MS), whereas others allow the option of pursuing a concurrent PhD or MS degree. Following successful completion of this training the Oral and Maxillofacial Radiologist becomes Board eligible to challenge the American Board of Oral and Maxillofacial Radiology examination. Successful completion of board certification results in Diplomat status in the American Board of Oral and Maxillofacial Radiology.


Australian programs are accredited by the Australian Dental Council (ADC) and are 3 years in length and culminate with either a master's degree (MDS or MPhil) or a Doctor of Clinical Dentistry degree (DClinDent).[8] Fellowship (FRANZCR) can then be acquired through the Royal Australia New Zealand College of Radiologists and/or the (FRACDS) Royal Australasian College of Dental Surgeons.


Canadian programs are accredited by the Canadian Dental Association (CDAC) and are a minimum of two years in length and usually culminate with a Master of Science (MSc) degree. Graduates are then eligible to sit for the Fellowship exams with the Royal College of Dentists of Canada (FRCD (C)).[9][10]

United Kingdom[edit]

Programs in the United Kingdom are 4 years in length and culminate in a Certificate in Completion of Specialty Training (CCST) and often a Master of Science degree (MSc). Graduates are then eligible to sit for the Diploma of Dental Radiology from the Royal College of Radiologists (FRCR DDR).[11]
