INBDE flashcards & board prep
Integrated National Board Dental Examination
The INBDE doesn't ask you to recite biochemistry and dentistry in separate silos — it hands you a patient and expects you to connect the two. This path walks the whole test blueprint the way the exam integrates it: the biomedical foundations first, then the clinical disciplines that build on them, then the diagnosis-and-treatment-planning cases that tie everything together. Every topic comes with a flashcard deck for recall and a set of board-style questions for application, so you're not just memorizing — you're rehearsing the exact move the INBDE tests.

What is the format of the INBDE?
500 multiple-choice items — a mix of discrete questions and patient-case-based sets — administered over two testing days.
How long is the INBDE?
Two days: roughly 4 hours on Day 1 (~200 items) and 5 hours on Day 2 (~300 items).
When can I take the INBDE?
Offered year-round by appointment at Prometric test centers, so you can sit it when your prep is ready rather than waiting for a fixed window.
How is the INBDE scored?
Reported as pass / fail. The passing standard is a scaled score of 75; a numeric score is only released to candidates who do not pass.
How hard is the INBDE?
First-time pass rates are high, but the integrated, case-based format reliably catches students who learned facts in isolation instead of in clinical context.
Who takes the INBDE?
Taken by dental students (after the required biomedical coursework) and international graduates; a passing result is required for licensure in the United States.
