NBDHE Questions and Answers

What topics are covered on the NBDHE?

The NBDHE covers three major content areas: scientific basis for dental hygiene practice, provision of clinical dental hygiene services, and community health and research principles. Specific subjects include anatomy, physiology, pharmacology, microbiology, pathology, radiology, periodontology, dental materials, patient management, and ethics. Questions are presented as patient case-based scenarios and standalone items that test applied knowledge rather than rote memorization.

Who is eligible to take the NBDHE?

Candidates must have graduated from or be enrolled in their final year of a dental hygiene program accredited by the Commission on Dental Accreditation (CODA). Students in their final year may take the exam up to 90 days before their expected graduation date. International dental hygiene graduates must have their credentials evaluated and meet additional requirements set by the Joint Commission on National Dental Examinations.

How do I register for the NBDHE?

Registration is handled through the Joint Commission on National Dental Examinations via the American Dental Association website. You create an account on the JCNDE portal, submit your application with proof of eligibility from your dental hygiene program, pay the examination fee, and then schedule your test date and location through Pearson VUE, which administers the exam at testing centers nationwide.

How many times can I retake the NBDHE?

Candidates who do not pass may retake the NBDHE, but there is a waiting period of at least 60 days between attempts. After three failed attempts, candidates must wait one full year before testing again. Each retake requires a new application and full payment of the examination fee. Some state dental boards may impose additional limits on the total number of attempts allowed.

What is the format of the NBDHE questions?

The NBDHE uses multiple-choice questions in two distinct formats. Component A contains approximately 200 standalone discipline-based items. Component B presents 150 questions based on 12 to 15 dental hygiene patient cases, each including medical histories, dental charts, radiographs, and clinical photographs. All questions have four or five answer choices with a single correct response.

What score do state boards require for NBDHE licensure?

While the NBDHE itself uses a pass/fail standard score of 75, individual state dental boards set their own requirements for accepting the exam. Most states accept the standard passing score, but some may require a higher scaled score for licensure eligibility. Check with your specific state board of dentistry, as requirements vary and some states also mandate additional regional or state-specific clinical examinations.

How should I prepare for the NBDHE case-based questions?

Focus your study on integrating knowledge across multiple disciplines rather than memorizing isolated facts. Practice reading patient cases that combine medical history, pharmacology, radiographic interpretation, and treatment planning. Review dental hygiene process of care steps systematically. Use timed practice tests to build stamina for the nine-hour exam day, and study radiograph interpretation regularly since case-based questions heavily feature dental imaging.

Can I use the NBDHE score to get licensed in any state?

The NBDHE is accepted as part of the licensure process in all 50 states, the District of Columbia, and most U.S. territories. However, passing the NBDHE alone does not grant a license. Most states require additional components such as a clinical board examination, jurisprudence exam, CPR certification, and completion of a state-specific application process before issuing a dental hygiene license.
