DABOM study guide
DABOM · Work through your exam, one topic at a time.
The DABOM credential - the Diplomate of the American Board of Oral Medicine - is a professional certification for dentists who have completed advanced training in oral medicine and who want external validation of their judgment in medically complex oral care. It signals that a clinician can evaluate and manage patients whose oral findings sit at the intersection of dentistry and medicine: mucosal disease, orofacial pain, salivary dysfunction, and oral manifestations of systemic illness. The DABOM study guide has 8 sections and about 3,090 words.
01Oral Medicine Diagnosis and Assessment
Domain 1 tests whether you can turn a patient's story into a defensible differential diagnosis and a diagnostic plan. Questions emphasize the order of assessment, the meaning of test results, and the decision to biopsy, image, or refer rather than a memorized disease list.
475 words, about 2 min02Orofacial Pain and Temporomandibular Disorders
Domain 2 tests mechanism-based classification and conservative management of pain arising from the masticatory system, cranial nerves, and central pain processing. The exam favors questions that separate nociceptive, neuropathic, and nociplastic pain and that apply DC/TMD criteria rather than vague labels such as TMJ.
398 words, about 2 min03Oral Mucosal Diseases and Mucocutaneous Disorders
Domain 3 tests pattern recognition and the biopsy pathway for white, red, ulcerative, and vesiculobullous mucosal disease. The exam rewards a precise description of distribution and morphology, because that description determines whether you biopsy, test with DIF, or treat empirically.
397 words, about 2 min04Oral and Maxillofacial Pathology and Oral Oncology
Domain 4 tests risk assessment, biopsy strategy, and staging of oral potentially malignant disorders and oral cancer, plus recognition of common salivary and odontogenic tumors. The exam emphasizes what changes management: dysplasia, depth of invasion, margins, and neck status.
396 words, about 2 min05Salivary Gland Disorders and Xerostomia
Domain 5 tests the difference between the symptom of dry mouth and objective salivary hypofunction, the workup of salivary swelling, and the systemic causes of gland dysfunction. The exam favors questions about medication review, Sjögren syndrome criteria, and complications of hyposalivation.
369 words, about 2 min06Oral Manifestations of Systemic Disease and Medical Management
Domain 6 tests whether you can recognize oral signs of systemic disease and modify dental management accordingly. The exam favors questions that link a mucosal or periodontal finding to an underlying condition, medication, or organ failure.
356 words, about 2 min07Pharmacology and Therapeutics in Oral Medicine
Domain 7 tests drug selection, dosing, monitoring, and interactions for the medications used in oral medicine. The exam favors questions about topical versus systemic corticosteroids, antifungal choice, antiviral timing, and safe prescribing in pregnancy and organ disease.
354 words, about 2 min08Oral Infection and Immunity, Including Oral Microbiology
Domain 8 tests the microbiology of common oral infections, the immune response that contains them, and the principles of antimicrobial stewardship and infection control. The exam favors questions that distinguish viral, fungal, and bacterial disease and that avoid unnecessary antibiotics.
