Confidentiality & Applicant Conduct

The examination and all related materials are ABDSM’s confidential, proprietary and copyrighted intellectual property. Any disclosure of the contents of the examination is strictly prohibited. Applicants may not cheat, participate in any cheating incident, breach of security, misconduct or any other behavior that could compromise the integrity or confidentiality of the ABDSM certification examination. In order to sit for the examination, all applicants must carefully review and agree to abide by the terms of the ABDSM Examination Confidentiality & Applicant Conduct Policy.

Applicants with Disabilities

The ABDSM recognizes that individuals with disabilities may wish to take the examination and will make reasonable accommodations for applicants with verified disabilities. The ABDSM supports the intent of the Americans with Disabilities Act. Applicants are reminded, however, that auxiliary aids (and services) can only be offered if they do not fundamentally alter the measurement of skills or knowledge the examination is intended to test (Americans with Disabilities Act, Public Law 101-336). Applicants who request accommodations due to a disability must advise the ABDSM in writing no later than January 1, 2019. The applicant may be asked to submit appropriate documentation of the disability and a description of previous accommodations provided during other examinations. If the ABDSM deems it necessary, an independent medical assessment may be requested at the expense of the ABDSM. 

Examination Composition

The ABDSM Board of Directors directs all aspects of the certification examination including composition.


All scoring is performed without knowledge of the applicant’s identity, and all decisions concerning examination scoring are made before the matching of names and applicant code numbers. Individual scores will not be changed.

Examination Results

Applicants are informed of a passing score or a failing score via mail. Actual scores, regardless of the results, will not be provided. Results are not available by telephone. Information regarding the number of applicants who passed or failed the examination will not be provided.

Appeal Procedure

Applicants may appeal a negative determination (rejection of prerequisites or failure of examination) by submitting a written explanation of the reason for refuting the determination with a nonrefundable appeal fee of $395. This appeal must be made within 30 days of the date of the notification letter. All materials must be submitted in writing to the American Board of Dental Sleep Medicine, 1001 Warrenville Road, Suite 175, Lisle, IL 60532.

Professional Designation

Upon notification by the ABDSM, individuals may use the following options to display their respective credential:
  • Diplomate, American Board of Dental Sleep Medicine
  • Diplomate, ABDSM
  • D. ABDSM 
  • International Certificant, American Board of Dental Sleep Medicine
  • International Certificant, ABDSM
The use of these credentials in any form prior to notification by the ABDSM Board of Directors that all requirements have been successfully completed is strictly prohibited. Diplomate status does not denote specialty status or specialty recognition. Furthermore, it does not confer or imply any legal qualification, licensure, or privilege in professional activities as they relate to oral appliance therapy or oral surgery for sleep disordered breathing. It signifies a professional commitment to education, knowledge and experience in dental sleep medicine. It recognizes those dentists duly licensed by law who have successfully completed the board certification requirements established by the ABDSM.


These guidelines are not intended to supersede state dental practice acts. The ABDSM advises all dentists to contact the dental licensing board in their state to verify the approved scope of practice for their license and practice accordingly.

The ABDSM board is self-designated and does not confer recognized specialty status by any other certifying organization. Personal use of the ABDSM Diplomate and International Certificant designation shall be the responsibility of each individual. The ABDSM assumes no liability for how each individual displays their designation.

The ABDSM advises all Diplomates and International Certificants to follow the American Dental Association Principles of Ethics and Code of Professional Conduct when advertising their status. It is also strongly recommended that each individual consult their state or local regulatory agency and adhere to their requirements. Most state licensing agencies do NOT permit advertising the credential. The Diplomate designation should only be used if it does not conflict with each certificant’s local regulations and code of ethics.

These guidelines are subject to change without notice. The latest updates can be found at www.abdsm.org.
