Start testHow these NBDHE practice tests match the real exam
The real National Board Dental Hygiene Examination (NBDHE) has 350 questions. Question types: Multiple choice: 200 discipline-based items and 150 case-based items (12–15 patient cases). Each practice test here uses the same question formats, so you get used to how NBDHE questions are asked before test day.
The tests draw on every NBDHE content area, weighted like the official outline:
- Scientific Basis for Dental Hygiene Practice (about 17% of the exam)
- Provision of Clinical Dental Hygiene Services (about 76% of the exam)
- Community Health/Research Principles (about 7% of the exam)
Use tutor mode to see the explanation after each answer, or timed mode to practise at real exam pace. Every answer comes with an explanation of why it is right and why the other options are wrong.
