NBDE Exam Study Guide

Our comprehensive NBDE study material breaks down everything you need to know about the NBDE exam and the transition to INBDE. Whether you are searching for ADA NBDE guidelines or NBDE Part 1 historical context, this guide covers it all.

What is the NBDE exam?	The National Board Dental Examination (NBDE) was a two-part licensure test for dentists. It has largely been replaced by the Integrated National Board Dental Examination (INBDE), which combines content from NBDE Part 1 and NBDE Part 2 into one comprehensive exam.
Who takes the NBDE exam?	Dental students and graduates from accredited dental schools in the US and Canada, as well as international dentists seeking licensure in the United States, must take the NBDE exam (now INBDE).
What is the difference between NBDE and INBDE?	The NBDE exam was split into two parts: Part 1 (Basic Sciences) and Part 2 (Clinical Sciences). The INBDE integrates these topics into a single examination to better reflect modern dental practice.
Is the NBDE practice test still relevant?	Yes, taking an NBDE practice test is highly recommended. The foundational knowledge tested in NBDE Part 1 and NBDE Part 2 is identical to the content on the new INBDE, making legacy practice materials very valuable.
