NBDHE Practice Test with Latest Exam Questions 2026

The National Board Dental Hygiene Examination is required for dental hygiene licensure in the United States. It covers scientific basis, provision of clinical services and community health.

The American Dental Association and the Joint Commission on National Dental Examinations oversee admission and licensure exams for dentistry and dental hygiene in the United States. These exams are computer based and delivered at Prometric test centers.

The National Board Dental Hygiene Examination credential is built from a job or practice analysis, so the exam reflects the knowledge professionals actually use with patients and clients. Passing it is often required for licensure, employment or board certification, and it signals to employers that you meet a nationally recognized standard.

Here is how the main areas break down. Scientific Basis for Dental Hygiene Practice covers anatomic sciences: head and neck anatomy, dental anatomy, histology and embryology; physiology, biochemistry and nutrition; and microbiology and immunology. Within Provision of Clinical Dental Hygiene Services, candidates should be comfortable with assessing patient characteristics: medical/dental history, vital signs, head and neck exam; periodontal and dental charting; and radiographs: techniques, safety and interpretation. Community Health / Research Principles focuses on promoting health and preventing disease in communities; epidemiology and dental indices; and research methods and statistics.

Keep a one page summary for each area with key terms, steps and examples, and review these summaries every few days. Close your preparation with at least two complete timed practice sessions and a careful review of every missed question.

Questions on NBDHE are often long clinical vignettes. Practice reading the last line of the question first, then scanning the case for the details that matter. This habit saves time and reduces the chance of being distracted by irrelevant information.
