NBDHE General Information

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

Important Note Concerning Periodontics Terminology:

In 2017, the American Academy of Periodontology introduced new classifications. These new classifications will be implemented in the fall of 2021 for the NBDHE. Download the classification information 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 available on the American Academy of Periodontology website
