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.
