Premium · Full-length simulation

Rehearse the whole exam day.

The real NBDHE is 350 items in one sitting — 200 discipline-based questions and 150 case-based questions across a dozen patient cases. This is the full thing, in exam-day format: patient boxes with perio charts and findings, a flag-and-review navigator, an optional clock, and a score report mapped to all 13 discipline areas plus the case component.

✓True length and structure. 200 discipline + 150 case = 350 items, weighted to the JCNDE blueprint (62% Clinical · 28% Scientific · 10% Community), discipline first, then the cases — just like test day.
✓Case testlets with exhibits. Each case opens with a patient history, a periodontal chart, and radiographic and clinical findings you read to answer 12–15 linked questions.
✓Flag, skip, and come back. Navigate freely, flag anything you’re unsure of, and review before you submit. No feedback until the end.
✓It saves as you go. Close the tab and pick up exactly where you left off — a 350-item exam doesn’t have to happen in one sitting.

Optional break

You’ve finished the 200 discipline-based questions. On test day, this is where an optional scheduled break falls. Next come the patient cases — Component B. The clock is paused.

Readiness by discipline area

The official score report breaks performance into 13 discipline areas plus the case component. Your weakest areas here are where your next study sessions belong.

This full-length simulation is a study aid. It is not an official NBDHE practice exam, is not a scaled score, and does not predict your pass/fail result (the JCNDE reports a scaled score with 75 as passing). Items are weighted to the JCNDE discipline blueprint as updated for 2026. The House of Hygiene is not affiliated with or endorsed by the Joint Commission on National Dental Examinations.
