ExploreAbout this exam
The American Board of Oral and Maxillofacial Radiology (ABOMR) certification examination is a professional credentialing assessment for dentists who practice, teach, or research oral and maxillofacial radiology and who wish to demonstrate specialty-level competence. Candidates are typically graduates of, or trainees in, advanced oral and maxillofacial radiology programs, but the credential is also relevant to academically oriented radiologists and clinicians whose practice depends heavily on diagnostic imaging interpretation. The exam spans the full discipline: radiation physics and biology, equipment and acquisition technique, image processing, quality assurance and safety, normal anatomy and developmental anomalies, cystic and neoplastic disease interpretation, inflammatory, traumatic and metabolic bone disease, temporomandibular joint, salivary gland and soft tissue imaging, advanced modalities such as CBCT, CT, MRI, ultrasound and nuclear medicine, and professional, ethical and practice standards. Preparation is best built around a structured review of each domain rather than a single cram source: work through standard textbooks in oral and maxillofacial radiology and head and neck imaging, read current journal literature on imaging technique and diagnosis, and practice systematic film and volume interpretation on cases you can defend out loud. Because the exam is case-based in part, candidates should rehearse a repeatable interpretive routine.

What you'll study
About ABOMR preparation
What is the ABOMR certification examination for?
It is the board certification assessment for oral and maxillofacial radiology, intended to document that a candidate has specialty-level knowledge of imaging physics, technique, safety, anatomy, and diagnostic interpretation across the maxillofacial region. It is generally pursued by advanced-program graduates and academically oriented radiologists.
What format should I expect?
Expect multiple-choice items plus case-based interpretation questions in which you review imaging information and select the most likely diagnosis, the next best step, or the key finding. The board publishes the current format and any written components, so confirm specifics on its official site before you plan your study.
How long is the exam and how many questions does it have?
The ABOMR publishes the current question count and timing for each administration, and these details can change between cycles. Rather than rely on secondhand numbers, check the official board website for the figure that applies to your exam date.
How hard is it?
It is a specialty board examination, so difficulty is high: it assumes working command of physics and biology, not just pattern recognition. Most candidates find the case-based interpretation sections the most demanding because they reward a disciplined, systematic reading routine rather than isolated fact recall.
What happens if I do not pass, and can I retake it?
Retake rules, waiting periods, and any limits on attempts are set by the board and are subject to change. The ABOMR website is the authoritative source for the current retake policy, so read it before you apply rather than assuming a fixed waiting period.
In what order should I study the domains?
Start with physics, radiation biology, and acquisition and safety, because those concepts underpin image quality and interpretation. Then move to anatomy and developmental anomalies, followed by cysts, tumors, and inflammatory and traumatic disease, and finish with TMJ, salivary, soft tissue, and advanced modalities, integrating professional standards throughout.
What are the most common failure modes?
Weak physics fundamentals that make artifact and technique questions guesswork, memorizing diagnoses without a systematic interpretive approach, and neglecting advanced modalities such as MRI and ultrasound. Another frequent problem is studying only from question sets instead of reading primary texts and current literature.
Where do I find fees, eligibility, and application deadlines?
Those are administrative details the board controls and updates. The ABOMR official website publishes current fees, eligibility requirements, application windows, and deadlines; treat any figure you see elsewhere, including on this page, as unverified.
Is this page an official ABOMR resource?
No. This is independent study material written for exam preparation and is not affiliated with, endorsed by, or connected to the American Board of Oral and Maxillofacial Radiology. Always verify policies and exam details directly with the board.
