Free DHA Oral & Maxillofacial Surgery mock test
12 original exam-style questions from our Oral & Maxillofacial Surgery bank, timed at the exam’s own pace, scored against the 60% DHA pass mark. They span 7 of the 10 blueprint domains, so you will see exactly where you are weakest - free, no sign-up.
Sit 12 original exam-style questions at real exam pace
These are 12 original questions taken from our Oral & Maxillofacial Surgery bank, spread across 7 of the 10 domains of the published blueprint. You get 72 seconds per question, which is exactly the pace of the real OMS5351 exam (14 minutes for 12). At the end you will see which domains you are weakest in, and the full worked reasoning for every question.

What the real Oral & Maxillofacial Surgery licensing exam looks like
Candidates for a Oral & Maxillofacial Surgery licence in the UAE sit a computer-based multiple-choice examination - DHA exam code OMS5351, delivered through Prometric for DHA, MOHAP and SHA, and through Pearson VUE for DOH Abu Dhabi. The DHA pass mark is 60% (DHA CBT Guideline, Sep 2026); other authorities set their own, so confirm yours before booking. The result is reported to you as pass or fail only - your score is never released.
Pass marks at a glance: DHA exam codes and pass marks for all written exams in one sourced table.
The paper is built to a published blueprint, which is why a domain-by-domain diagnostic is more useful than a raw percentage. Your questions above were drawn from across Anaesthesia, Sedation and Medical Emergencies, Dentoalveolar Surgery, Maxillofacial Trauma, Oral Pathology, Cysts and Tumours and 3 more - the same areas the real paper weights.
Before you can book the exam at all you need Dataflow primary source verification of your degree, licence and experience, which typically runs several weeks. Candidates routinely underestimate this and end up sitting the exam sooner after study than they planned. Check where you stand with our free eligibility checker or confirm whether your title even requires an exam using the Prometric exam checker.
You get three attempts in total across all UAE authorities - not three each - under the Unified Professional Qualification Requirements. At roughly AED 1,030 per attempt, plus the licensing delay each failure adds to your visa and start date, the cost of going in underprepared is not really the exam fee.

A worked Oral & Maxillofacial Surgery exam question
Every question in the diagnostic and in the paid bank is written to this standard: a clinical stem, four plausible options and the reasoning for the answer, with its source.
Anaesthesia, Sedation and Medical Emergencies
An adult develops wheeze, facial swelling and hypotension minutes after an intravenous antibiotic in the clinic. What is the correct first dose of adrenaline?
- A0.5 mg intramuscularlyCorrect
- B1 mg intravenously as a bolus
- C0.05 mg subcutaneously
- D5 mg by nebuliser
Why: Adult anaphylaxis is treated with 0.5 mg (0.5 mL of 1 mg/mL) adrenaline intramuscularly into the anterolateral thigh, repeated after 5 minutes if needed. A 1 mg intravenous bolus is for cardiac arrest and can cause dangerous arrhythmias in a patient with a pulse. The subcutaneous route absorbs unreliably.

Oral & Maxillofacial Surgery sample questions with answers
4 more original exam-style Oral & Maxillofacial Surgery questions, worked in full. They are not real or recalled exam questions, and none of them is in the diagnostic above, so sit that first if you have not.
Question 1 · Anaesthesia, Sedation and Medical Emergencies
A nervous patient becomes pale, sweaty and briefly loses consciousness during local anaesthetic injection. The pulse is slow but present. What is the most appropriate first action?
- ALay the patient flat and raise the legs
- BGive adrenaline 0.5 mg intramuscularly
- CStart chest compressions immediately
- DGive oral glucose gel into the cheek
Show answer and explanation
Correct answer: A. Lay the patient flat and raise the legs
This is vasovagal syncope, and laying the patient flat with the legs raised restores cerebral blood flow and usually brings quick recovery. Chest compressions are only for absent signs of life. Adrenaline is for anaphylaxis, and glucose is for hypoglycaemia.

Question 2 · Head and Neck Oncology
A 55-year-old has a 2.5 cm squamous cell carcinoma of the lateral tongue with depth of invasion of 6 mm and a clinically and radiologically negative neck. What is the most appropriate management of the neck?
- AObservation with ultrasound every 3 months
- BElective selective neck dissection of levels I to III
- CRadical neck dissection of levels I to V
- DNeck radiotherapy only after the primary heals
Show answer and explanation
Correct answer: B. Elective selective neck dissection of levels I to III
Early oral cancer with significant depth of invasion carries a high risk of occult nodal disease, and a randomised trial showed better survival with elective neck dissection than with watchful waiting. A selective dissection of levels I to III is standard for the N0 neck. Radical dissection adds morbidity without benefit in this setting.
Reference: D'Cruz et al., Elective versus therapeutic neck dissection in node-negative oral cancer, N Engl J Med 2015
Question 3 · Head and Neck Oncology
A patient is to start radiotherapy to the oral cavity in 3 weeks. He has a grossly carious, unrestorable lower molar within the planned field. What is the best plan for this tooth?
- AExtract it now to allow healing before radiotherapy
- BLeave it and extract it 6 months after radiotherapy
- CRestore it temporarily and review after treatment
- DExtract it during the first week of radiotherapy
Show answer and explanation
Correct answer: A. Extract it now to allow healing before radiotherapy
Teeth with a poor prognosis in the radiation field should be extracted before radiotherapy, ideally allowing about 2 weeks for healing, because extraction from irradiated bone carries a high risk of osteoradionecrosis. Delaying extraction until after treatment increases that risk. Temporary restoration of an unrestorable tooth only postpones the problem.

Question 4 · Head and Neck Oncology
Which oral mucosal lesion carries the highest risk of containing dysplasia or carcinoma when first biopsied?
- AHomogeneous leukoplakia
- BOral lichen planus
- CFrictional keratosis
- DErythroplakia
Show answer and explanation
Correct answer: D. Erythroplakia
Erythroplakia, a red patch not attributable to another condition, very often shows severe dysplasia, carcinoma in situ or invasive carcinoma at first biopsy. Homogeneous leukoplakia has a lower risk than non-homogeneous or red lesions. Frictional keratosis resolves when the cause is removed.

How to use this diagnostic properly
- 1Sit it cold, once. Do not look anything up. A diagnostic you help yourself through tells you nothing. The number you get is only useful if it is honest.
- 2Read every rationale - especially the ones you got right. Getting a question right by elimination is not the same as knowing it. The worked reasoning is free above, whether or not you buy anything.
- 3Work weakest domain first. The breakdown orders your domains worst-first for exactly this reason. Studying what you are already good at feels productive and moves nothing.
- 4Re-sit under full exam conditions later. The real paper is far longer than this and stamina matters. Full-length timed papers are what the paid bank is for.
