START INFECTION CONTROL PRACTICE TESTSample National Dental Assisting Examination Board Practice Questions
Try these questions from our free National Dental Assisting Examination Board practice tests. The correct answer and an explanation follow each question.
Following a complicated extraction in which the patient experienced a dry socket, the dentist asks the dental assistant to add a note to the chart backdated to the day of the procedure, stating that post-operative instructions were verbally reviewed and a printed sheet was provided. The dental assistant is not certain whether this actually occurred. What should the dental assistant do?
- A. Add the note as requested since backdating records is common practice for completeness
- B. Decline to add the note, as entering information that may be inaccurate constitutes falsification of a legal document
- C. Add the note with today's date but describe the instructions as having been given on the original date
- D. Consult the provincial regulatory body anonymously before deciding whether to comply
Answer: B. Decline to add the note, as entering information that may be inaccurate constitutes falsification of a legal document
Dental records are legal documents, and entering false or unverified information β including backdating entries or documenting events the writer did not witness β constitutes falsification of records. This exposes the dental assistant to professional discipline and potential civil or criminal liability. The dental assistant's obligation to accuracy and integrity in documentation must take precedence over a dentist's instruction when that instruction would require dishonesty.
A dental assistant who is active on social media posts a photo taken in the dental operatory after the office has closed for the day. The image is intended to showcase new dental equipment. In the background, a patient's name is visible on a wall-mounted appointment board. The dental assistant does not tag the patient or mention them in the caption. Which of the following statements is correct?
- A. No privacy breach has occurred because the dental assistant did not intentionally identify the patient or post clinical information
- B. A privacy breach has occurred because a patient's name is personal health information and its incidental disclosure in a public post is still a reportable breach
- C. No breach has occurred because the photo was taken after office hours when no patients were present
- D. A breach would only occur if the patient filed a formal complaint with the privacy commissioner
Answer: B. A privacy breach has occurred because a patient's name is personal health information and its incidental disclosure in a public post is still a reportable breach
Under PIPEDA and provincial health privacy legislation, a patient's name linked to a dental office visit constitutes personal health information. Even incidental disclosure β such as a name appearing in the background of a social media photo β is a privacy breach if it could allow an identifiable individual to be associated with a health care setting. Intent is not required for a breach to occur; unauthorized disclosure is the determining factor.
After seating a full-coverage porcelain-fused-to-metal crown, the dentist asks the dental assistant to help evaluate the occlusion. The patient bites on articulating paper and reports the crown feels 'high.' Which instrument should the dental assistant have ready for the dentist to use next?
- A. A flame-shaped finishing bur in the high-speed handpiece
- B. A round carbide bur in the slow-speed handpiece
- C. A fine diamond or finishing bur in the high-speed handpiece to selectively adjust the marked contact
- D. A rubber polishing cup with pumice to polish the marked area
Answer: C. A fine diamond or finishing bur in the high-speed handpiece to selectively adjust the marked contact
High spots on ceramic or PFM restorations are adjusted using a fine diamond or finishing bur in the high-speed handpiece on the exact area marked by the articulating paper. This allows precise, selective reduction. A coarse or round bur would remove too much material indiscriminately, and polishing would not reduce occlusal height.
A dentist asks a Level II dental assistant to take final impressions for a crown, a task that is outside the assistant's legal scope of practice in their province. If the assistant complies and the patient is harmed as a result, who could be held liable for professional negligence?
- A. Only the dentist, as they delegated the task.
- B. Only the dental assistant, as they performed the task.
- C. Neither, as the assistant was following the dentist's orders.
- D. Both the dentist and the dental assistant.
Answer: D. Both the dentist and the dental assistant.
Dental assistants are responsible for practicing within their legal scope of practice, regardless of who delegates a task. The dentist is liable for improper delegation and for the actions of their employee under the doctrine of vicarious liability. The dental assistant is also liable for knowingly performing a task for which they are not legally authorized. Therefore, both parties share liability.

NDAEB Questions and Answers
Free NDAEB Practice Exam Options
Most candidates start their prep by looking for a free NDAEB practice exam they can take under timed conditions before spending money on paid materials. The practice test modules on this page cover every blueprint domain β Patient Care Procedures, Dental Sciences Foundations, Infection Prevention and Control, and more β so you can simulate the real 200-item, 4-hour Theory Exam section by section instead of guessing which topics need work.
Searching for an NDAEB exam practice test free option is a smart first step, but pair it with the official NDAEB Theory Exam Candidate Handbook so your practice matches the real blueprint weighting, not just general dental-assisting trivia. Some candidates also look for an NDAEB Quizlet deck for quick flashcard-style review between study sessions; that kind of spaced repetition is useful for memorizing terminology and infection-control steps, but it should supplement, not replace, full-length timed practice exams that mirror the actual case-based question style.
The NDAEB itself also sells an official $75 practice examination through the Candidate Portal, which is the closest simulation to the real test-day experience. Combining that official practice exam with the free quizzes on this page and the flashcards above gives you both breadth (every blueprint domain) and realism (official item style) before your September 23-25 or December 9-11, 2026 sitting.
