Note: The Oregon Board of Dentistry will discontinue administration of the Oregon Basic (ORB) exam in 2024. DANB will no longer accept application for the ORB exam after 1/5/2024, and administration of the ORB exam will be discontinued by 6/1/2024. To meet the Pathway III eligibility requirements for the EFDA, EFODA, and EFPDA certificates, candidates will instead be required to pass DANB’s Infection Control (ICE) exam. Candidates who passed the ORB prior to its discontinuation will still be able to use their ORB result to qualify for an Oregon expanded function certificate.
