The process of care, area by area.

The NBDHE is 350 questions: 200 discipline-based across three areas, then 150 on patient cases. Every question here carries its area, so you see which part of the process of care is short.

Weights are the JCNDE NBDHE discipline-based component (61 / 115 / 24 of 200 items, 2026 Candidate Guide); the 150 case-based items test the same clinical services. JCNDE has announced updated specifications for November 2026. Weak Spots drills the red ones.

Five things built for the dental hygienist.

Every plan opens everything. These are the five that matter most for this exam, shown the way you’ll meet them.

1Practice papers

Twelve practice papers of 200

The real paper is 350 questions. Our practice papers are 200 items. Every item is tagged to the three JCNDE content areas, so your score is reported area by area. 1,961 original questions in all, counted once.

2Explanations

Every wrong answer gets its own reason

Each explanation says why the right answer is right and why each distractor fails — the exact line you would want if you had picked it. Every item is checked blind by a second AI model that never sees the key. This one is a real item from the On-level 1 form.

ON-LEVEL 1PERIODONTICSMEDIUM FORM

At a maintenance visit, a previously stable site now shows a 2 mm increase in probing depth with BOP.

The most appropriate response is:

A
Re-instrument the site, reinforce hygiene, and monitor or treat as a recurrent lesionSite-specific deepening with bleeding at maintenance signals recurrence; the clinician re-debrides, reinforces home care, identifies local factors, and escalates care if needed.
B
Ignore it until the next annual visitignoring an active recurrent site allows progression
C
Immediately extract the toothextraction is premature for a treatable recurrent lesion
D
Prescribe lifelong systemic antibiotics in light of the patient history and clinical signsroutine lifelong antibiotics are not indicated for a localized recurrence
3Axon Live

A tutor who asks what you do first — and why

Say what you are stuck on, out loud. Axon teaches the section in the voice of the dental hygiene national board (JCNDE), draws the reasoning on a board as it speaks, and quizzes you on it before it moves on. It knows your syllabus, your weak spots and where you left off.

  • Teach me, Quiz me, I’ll listen, Why I missed it, Cram
  • Fifteen free minutes to meet it, once; top up in packs after that
  • Every session leaves a recap you can reopen

Questions

Before you start

Are the practice exams the real length?

The real NBDHE is 350 questions: 200 discipline-based, then 150 on twelve to fifteen patient cases. Our twelve practice papers are 200 items each (the discipline-based component); the full mock draws 350 from all of them. Case-based testlets with charts and radiographs are not built yet, and we say so.

Why do some lectures come from the INBDE course?

The hygiene bank is built on the same dental core as our INBDE course, so four of the six lectures are that core’s — the biomedical sciences, radiology and diagnosis, oral medicine and ethics — read at the hygienist’s depth. The other two are written for the hygienist: the process of care and community health and research.

Are these real exam questions?

No. Every item is original, written to the public content outline and checked blind by a second AI model that never sees the key. Nothing is copied from a published form, and we are not affiliated with any examining board.
