Dental Assistant Exam Prep CDA

CDA exam prep for the DANB Certified Dental Assistant exams, with focused RHS, ICE and General Chairside practice. Choose the component you need, try free questions with explanations, and build a study routine that fits your exam date.

THREE COMPONENTS, CLEAR STUDY CHOICES

Radiation Health and Safety (RHS): review imaging purpose and technique, radiation protection, and radiographic infection prevention.

Infection Control (ICE): practise disease transmission, cross-contamination prevention, instrument processing, and occupational safety.

General Chairside Assisting (GC): study evaluation, patient management, chairside dentistry and dental materials.

WHAT IS INCLUDED

- 1,315 original practice questions across 11 study areas.

- Answer explanations and reasons for the individual choices.

- 18 study notes and 180 flashcards for focused review.

- Separate RHS, ICE and GC timed practice mocks, accessible from Home.

- Wrong-answer review, bookmarks and locally saved study progress.

- An optional exam date and daily study-time plan.

START WITH A FREE SAMPLE

Select RHS, ICE or GC during the introduction, or try a mixed sample. Answer a question and read its explanation before deciding what to study next. Skip the introduction at any time and continue with free study. The sample describes only the answers you just gave; it does not predict your exam result.

The free version includes preview questions and selected topics, plus a limited mock trial. The app shows the available study paths and locked content. Premium unlocks the full bank and additional study access through a one-time purchase. No subscription. Existing customers can restore access with the store account used for their purchase.

PRACTISE FOR THE COMPONENT YOU NEED

Use this CDA practice test and dental assistant study app for an RHS review session, an ICE infection-control refresher, or a longer GC study session. Start with a topic, read the reasoning behind each answer, then return to missed questions. Review what you have actually studied using your saved progress.

Timed practice tests use 75 questions in 60 minutes for RHS, 75 in 60 minutes for ICE, and 95 in 75 minutes for GC. These are fixed practice tests; they do not reproduce DANB's adaptive testing. Current RHS testing is digital-only; retained film-related study material is supplementary background. The app's 75% study target is not DANB's scaled passing score and is not a guarantee of passing. Each CDA component must be passed under DANB's requirements.

STUDY AROUND YOUR DAY

Set an optional daily time budget and exam date, or begin without a plan. Use the bundled questions, explanations, notes and flashcards offline. Store purchases, restoration and external source links need a connection. No study account is required to start practising.

FREE EXAM INFORMATION

Open the CDA exam guide from Home to check component formats, eligibility, published examination fees, scoring and official sources. The guide distinguishes the announced early-2027 eligibility pathway from a change to the exam content. Check DANB for the requirements that apply to your application date and check your state for permitted dental assisting duties.
