Frequently Asked Questions
What is the NBDHE exam?
The National Board Dental Hygiene Examination (NBDHE) is a comprehensive standardized test that evaluates dental hygiene graduates' knowledge and skills in biomedical sciences, dental sciences, and clinical dental hygiene practice. Administered by the American Dental Association (ADA), it serves as a key requirement for licensure in most U.S. states, ensuring candidates meet national standards for safe and effective patient care.
How many questions are on the NBDHE?
The NBDHE consists of 350 multiple-choice questions divided into two main parts: 200 stand-alone discipline-based items covering foundational knowledge and 150 case-based items linked to 12-15 realistic patient scenarios that test clinical decision-making abilities.
What is the duration of the NBDHE exam?
Candidates face a total testing time of 7.5 hours, structured as two sessions: approximately 3.5 hours for the discipline-based section and 4 hours for case-based questions, including optional breaks to manage fatigue during the full-day commitment.
Who administers the NBDHE?
The American Dental Association (ADA) administers the NBDHE, handling registration, testing logistics through Pearson VUE centers, and score reporting, while its Joint Commission on National Dental Examinations (JCNDE) develops content to align with evolving dental hygiene standards.
What topics are covered in the NBDHE?
Content spans three disciplines:
- Scientific Basis for Dental Hygiene Practice (anatomy, physiology, microbiology)
- Provision of Clinical Dental Hygiene Services (radiology, pharmacology, treatment planning)
- Community Health/Research Principles (epidemiology, ethics, health promotion)
Is the NBDHE exam computer-based?
Yes, the NBDHE is a fully computer-delivered exam taken year-round at secure Pearson VUE testing centers, featuring an adaptive interface that allows navigation, flagging, and on-screen tools like a calculator for efficiency.
Do all states require the NBDHE for licensure?
Nearly all U.S. states and territories require the NBDHE for initial dental hygiene licensure, though some accept alternatives like CRDTS; always verify with your state board for specific mandates.
What preparation resources exist for NBDHE?
