NBDE Part I and Part II General Information

Click the blue box and check back daily for new information.  Important updates for all testing candidates regarding COVID-19  

NBDE Part I will be Discontinued

The Integrated National Board Dental Examination (INBDE) will be available for administration beginning on August 1, 2020. The NBDE Part I will be discontinued on July 31, 2020, and the NBDE Part II will be discontinued on August 1, 2022. More information is available on the INBDE webpages

In anticipation of this launch, candidates from non-accredited dental programs who have NOT yet successfully completed the NBDE Part I:

  • May NOT take the NBDE (Part I and Part II) after May 31, 2020.
  • Must take the INBDE to receive National Board Examination (NBE) certification, beginning August 1, 2020.
  • Any application submitted after November 30, 2019, will automatically be assigned a testing window that ends May 31, 2020.

Note: If a candidate from a non-accredited dental program has successfully completed the NBDE Part I by May 31, 2020, the candidate will still be eligible to take the NBDE Part II until July 31, 2022.

Candidates from accredited dental programs are not affected by this change.

Important Note Concerning Periodontics Terminology: 

In 2017, the American Academy of Periodontology introduced new classifications. These new classifications will be implemented in the summer of 2020. Download the classifications below.

During the transition period, it is recommended that individuals become knowledgeable with both sets of classifications, because individual researchers, practitioners, and existing textbooks can communicate information using either set of classifications. Periodontal educators recommend that individuals refer to the 2017 World Workshop On the Classification of Periodontal and Peri-implant Diseases and Conditions on the American Academy of Periodontology website
