What the ADC Written Examination looks like
For internationally qualified dentists, the Australian Dental Council assessment is the standard pathway to registration in Australia. The written examination is the knowledge stage. The ADC describes it as a computer-delivered, multiple-choice examination held over two days at Pearson VUE test centres around the world. It is usually offered twice a year, and there is currently no limit on attempts. The ADC candidate handbook sets out the blueprint and structure for each sitting; read it before you plan your study.
Our longer ADC written exam preparation guide covers the full pathway and blueprint. This article focuses on one thing: using practice questions well.
What ADC questions reward
Most candidates arrive with solid clinical knowledge. The difficulty is that ADC questions often describe a patient and ask for the most appropriate action. Several options may be clinically defensible somewhere; the correct one is safest and best supported for this patient, in an Australian practice setting. Three habits help:
- Find the deciding detail. Age, medical history, a medication or a time frame often changes the answer. Underline it mentally before you look at the options.
- Prefer the conservative, evidence-based step. When two options could work, the exam usually rewards the less invasive one that addresses the cause.
- Think about safety and consent. Questions on referral, documentation and informed consent are easy to underestimate and appear across branches.
Three worked examples
Try each question before opening the explanation, then read the note beneath it.
Question 1 · Oral Pathology · Head & Neck Oncology (Dental-Relevant Scope)
A painful ulcer on the buccal mucosa adjacent to a fractured restoration is treated by smoothing the sharp edge. Which follow-up finding would require biopsy?
- APain lasting more than three days
- BPersistence of the ulcer after two weeks
- CA white halo around the ulcer margin
- DYellow fibrinous slough on the ulcer base
Show answer and explanation
Answer: B. Persistence of the ulcer after two weeks
A traumatic ulcer with its cause removed should heal within 7-14 days; persistence beyond two weeks requires biopsy to exclude malignancy, a foundational rule of oral cancer screening.
Concept to remember: Remove the suspected cause, review in about two weeks, and biopsy any ulcer that has not healed.
This is a classic safety question. Smoothing the restoration is correct but not the end of management. The deciding detail is time: a traumatic ulcer should heal once the cause is removed, so persistence is the red flag. Exams test the review interval, not just the first step.
Question 2 · Pediatric Dentistry · Dental Trauma in Children
What is the goal of apexogenesis after vital pulp injury in an immature permanent tooth?
- ARemove all radicular pulp and permanently halt root maturation
- BCause physiologic resorption of the immature permanent root
- CPreserve vital radicular pulp so root development can continue
- DFill the open apex immediately with nonresorbable metal
Show answer and explanation
Answer: C. Preserve vital radicular pulp so root development can continue
Apexogenesis preserves healthy vital pulp tissue so dentin deposition, root lengthening, and apical maturation can continue. It may follow partial pulpotomy or another vital pulp procedure in a suitably diagnosed tooth. It differs from management of a necrotic immature pulp, where regenerative or apical barrier strategies are considered.
Concept to remember: Apexogenesis keeps the pulp vital so the root can keep developing; a necrotic immature tooth needs a different approach.
Paediatric trauma and pulp therapy questions often turn on whether the pulp is vital and whether the apex is open. Read the stem for both before choosing a technique.
Question 3 · Anesthesia & Pain Control · Management of Medically Complex Patients (Anesthesia Lens)
A 68-year-old male patient on long-term warfarin therapy (INR 2.5) requires a root canal treatment on a necrotic maxillary central incisor. Which of the following is the most appropriate management regarding his anticoagulant regimen?
- AProceed with the non-surgical root canal treatment without altering his warfarin dose.
- BLimit the treatment to tooth extraction under localized hemostatic measures.
- CConsult his physician to switch warfarin to low-molecular-weight heparin.
- DInstruct the patient to stop warfarin for 3 days prior to the appointment.
Show answer and explanation
Answer: A. Proceed with the non-surgical root canal treatment without altering his warfarin dose.
Non-surgical root canal therapy is a non-invasive procedure that does not cause significant bleeding. Therefore, warfarin therapy should not be altered, especially for patients with an INR within the therapeutic range (2.0-3.0).
Concept to remember: For low-bleeding-risk procedures in a patient whose INR is in the therapeutic range, the anticoagulant is usually not interrupted.
Medically compromised patients appear in every branch. The trap here is the option that sounds cautious but introduces a bigger risk: stopping an anticoagulant without medical advice. The exam rewards knowing when not to change a medication.
Building a practice routine
Practice questions work best in three layers, added over time rather than all at once.
Layer 1: topic sets
Study one topic, then answer 10 questions on it immediately. Review every answer, including the right ones, and flag any you guessed. This is where most learning happens, and it should fill most of your first two to three months.
Layer 2: mixed blocks
Once a group of branches is covered, answer 50-question blocks that mix them. Mixed practice shows whether you can recognise a topic without a heading telling you what it is, which is the real exam condition.
Layer 3: full mocks
In the last six to eight weeks, add full 100-question mock exams. Treat each as a diagnostic: group wrong answers by topic, send those topics back to layer 1, and only then sit the next mock.
Training for two days
Concentration over two consecutive days is a skill. Build it in steps: first a single 100-question mock in one sitting, then two mocks on consecutive days, sitting at the same times of day as your booked exam. Notice when your accuracy drops and practise short resets such as a brief pause every 25 questions, rereading the stem of any question that feels confusing, and not dwelling on one item. Sleep, food and travel to the test centre matter more than a last-minute topic on the morning of day 2.
Common mistakes
- Only doing mixed questions from day one. Mixed sets feel realistic but make it hard to see which topic failed.
- Counting guesses as correct. A lucky guess is a gap you have not found yet.
- Skipping ethics and practice management. These questions are short, but they are rarely easy marks unless you have practised them.
- Reviewing only wrong answers. The explanation for a right answer often reveals why another option was wrong, which is the next question on the same topic.
- Taking mock after mock without fixing anything in between. The same weak topics will simply reappear.
Where to start
Take the free 100-question ADC practice exam as a baseline: it covers all major disciplines and shows every explanation after you submit. Then use the free practice questions by branch to check your weakest areas, and the ADC preparation guide for the stages that follow the written exam.
Frequently asked questions
What is the format of the ADC Written Examination?+
The Australian Dental Council describes it as a computer-delivered, multiple-choice question examination held over two days at Pearson VUE test centres. The ADC candidate handbook gives the full structure and blueprint for each sitting.
How many times can I sit the ADC Written Examination?+
The ADC currently states that there is no limit on the number of attempts. It is usually offered twice a year. Always check the ADC website for current dates, fees and rules.
Are the practice questions on this page from the ADC?+
No. They are independently written questions from the DentistUP bank. They are not official, recalled or leaked ADC questions.
What makes ADC questions difficult?+
Many questions are scenario-based and ask for the most appropriate next step rather than a fact. Several options can be reasonable; the right one reflects safe, evidence-based and ethically sound Australian practice for the specific patient described.
How should I prepare for two days of testing?+
Build stamina gradually: move from focused 10-question sets to 50-question blocks, then to full 100-question mock exams, and practise at least once on two consecutive days before the real sitting.
