Frequently Asked Questions
What is the ABOM Oral Medicine Certification?
The American Board of Oral Medicine (ABOM) Certification validates expertise in the non-surgical medical management of oral and maxillofacial disease in medically complex patients. Oral medicine was recognized by the American Dental Association as a dental specialty in 2020. The certification process comprises a Written Examination, a Case Portfolio demonstrating breadth of oral medicine practice, and an Oral Examination — all administered by ABOM in partnership with the American Academy of Oral Medicine (AAOM).
Who is eligible to sit for ABOM certification?
Candidates must hold a D.D.S., D.M.D., or equivalent dental degree with an unrestricted dental license and complete a CODA-accredited oral medicine residency of at least 2 years. An alternative experience pathway is available for dentists with significant documented clinical and scholarly activity in oral medicine per ABOM eligibility requirements. Program director attestation and a Case Portfolio demonstrating breadth of practice are required.
What is the format of ABOM certification?
ABOM certification is a multi-component process: (1) Written Examination — computer-based multiple-choice test covering the oral medicine content outline; (2) Case Portfolio — submission of clinical cases spanning the breadth of oral medicine practice; (3) Oral Examination — case-based interview with examiners. Components are administered on separate dates. Successful completion of the Written Examination is required before progression to subsequent components.
How much does ABOM certification cost in 2026?
The 2026 ABOM examination fee is approximately $2,000-$2,500 — verify the current schedule on the ABOM website. Additional fees apply for Case Portfolio review and the Oral Examination. Ongoing continuing certification fees apply after initial certification. Cancellation and refund policies follow ABOM policy with decreasing refunds as the exam date approaches.
When is the 2026 exam administered?
ABOM administers its Written Examination, Case Portfolio review, and Oral Examination on published dates each year, typically with Written Examination offered annually or biennially and the Case Portfolio/Oral Examination scheduled in association with AAOM meetings. Exact 2026 dates and deadlines should be confirmed on the ABOM website.
How is the exam scored?
ABOM uses criterion-referenced scaled scoring with a passing standard set by subject-matter experts using the modified Angoff method. A candidate's pass/fail result depends on performance relative to the fixed cut-score, not on other candidates. The Case Portfolio and Oral Examination are graded against published ABOM rubrics. All components must be passed for Diplomate status.
What are the highest-yield topics?
Highest-yield topics include oral lichen planus and lichenoid reactions, pemphigus vulgaris (Nikolsky, anti-desmoglein, DIF intercellular), mucous membrane pemphigoid, Sjogren syndrome (anti-SSA/SSB, focus score, ACR/EULAR), MRONJ AAOMS 2022 staging, AHA 2007/2021 IE prophylaxis regimens (amoxicillin 2 g), candidiasis and antifungal selection (fluconazole vs echinocandins for resistant Candida), HSV/VZV/HPV oral manifestations, oral potentially malignant disorders (PVL, erythroplakia), burning mouth syndrome management (clonazepam, gabapentin, TCAs), and aphthous stomatitis workup.
How should I study for this exam?
Use a structured 12-18 month plan during and after oral medicine residency. Map to the ABOM content outline: begin with oral mucosal disease and autoimmune disease (DIF patterns), then salivary gland and Sjogren, infections, oral oncology and MRONJ, medical management of medically complex patients, pain and BMS/RAS, and diagnostic laboratory medicine. Integrate primary textbooks (Burket's Oral Medicine, Glick; Scully Oral and Maxillofacial Medicine), AAOM clinicians' guides, and current AAOMS and AHA guidelines. Build your Case Portfolio concurrently — do not delay case documentation.
