The NBDE is designed to evaluate the knowledge and skills of dental professionals, including dental students and graduates, to ensure they are competent and well-prepared for dental practice. Passing the NBDE is a requirement for dental licensure in the United States.

Two-Part Examination

The NBDE consists of two parts: NBDE Part I and NBDE Part II. Each part assesses different aspects of a candidate’s knowledge and clinical competence.



NBDE Part I primarily evaluates a candidate’s understanding of biomedical and dental sciences. It covers subjects such as anatomy, biochemistry, physiology, microbiology, pathology, and dental anatomy.

Question Format:

NBDE Part I is a computer-based examination with multiple-choice questions (MCQs). The questions assess a candidate’s comprehension of important dental and medical concepts.



NBDE Part II assesses a candidate’s clinical and patient management skills. It includes topics like patient assessment, diagnosis, treatment planning, and case management. It also evaluates the candidate’s understanding of the ethical and legal considerations of dental practice.

Question Format:

NBDE Part II consists of multiple-choice questions, case-based scenarios, and practical-based exercises that require candidates to make clinical decisions.
