What MJDF Part 1 Actually Tests
Before memorising facts, it helps to be precise about what "MJDF Part 1" refers to in 2026. The Royal College of Surgeons of England ran its final sitting of the original MJDF Part 1 in October 2020. Since then, the commercially relevant exam candidates actually sit is the unified tri-collegiate MFDS Part 1, developed by the Dental Examinations Executive on behalf of the Royal Colleges of Surgeons of England and Edinburgh and the Royal College of Physicians and Surgeons of Glasgow. Anyone searching "MJDF Part 1" today is almost always trying to prepare for this successor exam, and that is the exam this cheat sheet is built around.
Format-wise, the exam is a single-best-answer (SBA) test: 180 questions total, delivered as two separate papers of 90 questions each, with two hours allowed per paper and a short break in between. There is no negative marking, so an educated guess always beats leaving a question blank. If you want the full mechanics behind question style, timing, and scoring, the MJDF Part 1 Study Guide 2026 walks through first-attempt strategy in more depth.
The Legacy Name vs. Today's Exam
It's worth spending one paragraph on naming because confusion here wastes revision time. "MJDF Part 1" is a legacy term tied to the Royal College of Surgeons of England's original membership route, which stopped running new sittings after October 2020. The exam that replaced it in practical terms is the tri-collegiate MFDS Part 1, sat under joint governance of three Royal Colleges rather than one. If a resource you're reading quotes fee amounts, sitting dates, or pass statistics that don't match what you see on official assessment-centre booking pages, stop and cross-check - those figures may belong to an entirely different credential that happens to share the same acronym.
For a deeper unpacking of the terminology itself, see What Is MJDF Part 1?, MJDF Part 1 Meaning, and What Does MJDF Part 1 Stand For? - all three exist specifically to stop candidates studying the wrong content.
Eligibility and Attempt Rules at a Glance
Before you book, confirm you meet the four eligibility pillars:
- Primary qualification: an acceptable primary dental qualification recognised by the awarding colleges.
- Registration: current registration with a recognised dental regulator.
- Clinical experience: sufficient clinical experience to meet Dental Core Training (DCT) outcomes - this is not a paper-only exam route.
- English proficiency: a standard comparable to IELTS 7 if English is not your first working language.
Two numbers matter more than any others once you're eligible: you have four attempts at Part 1, and once you pass, Part 2 must be completed within four years of that Part 1 pass. Both limits shape how aggressively you should schedule revision rather than delaying a sitting "until you feel ready." A full breakdown of documentation and edge cases lives on the MJDF Part 1 Requirements page.
Key Takeaway
Treat the four-attempt ceiling as a planning constraint, not a safety net. Book your first sitting only once your domain-by-domain self-testing is consistently strong across the three heaviest domains.
The 19 Domains Ranked by Weight
The blueprint spans 19 domains, and question counts per domain are fixed ranges, not averages. Three domains dominate the paper:
Domain 5: Underpinning Clinical Knowledge (20-30 questions)
The largest single domain. Expect fundamentals of anatomy, physiology, pharmacology, and general medicine as they apply to dental practice.
Domain 6: Clinical Examination and Assessment (20-30 questions)
History-taking, extra-oral and intra-oral examination technique, and correct interpretation of clinical findings.
Domain 7: Diagnosis, Patient Management and Treatment Planning (20-30 questions)
Turning examination findings into a defensible diagnosis and a sequenced, patient-appropriate treatment plan.
Together these three domains can account for up to 90 of the 180 questions - potentially half the exam. Everything else on the blueprint sits in the 1-10 question range. For the complete list with descriptions of what each domain covers in practice, see the MJDF Part 1 Exam Domains 2026 guide.
| Domain | Question Range |
|---|---|
| 1. Professional Knowledge and Behaviour | 2-4 |
| 2. Patient-centred Care | 1-3 |
| 3. Teamworking | 2-4 |
| 4. Clinical and Patient Safety | 3-5 |
| 5. Underpinning Clinical Knowledge | 20-30 |
| 6. Clinical Examination and Assessment | 20-30 |
| 7. Diagnosis, Patient Management and Treatment Planning | 20-30 |
| 8. Emergency Care (Dental and Facial Injuries) | 6-10 |
| 9. Preventative Care and Maintenance of Oral Health | 6-10 |
| 10. Restorative Dentistry | 6-10 |
| 11. Orthodontics | 6-10 |
| 12. Oral Surgery | 6-10 |
| 13. Paediatric Dentistry | 6-10 |
| 14. Special Care Dentistry | 6-10 |
| 15. Oral Medicine | 6-10 |
| 16. Oral and Maxillofacial Pathology | 4-6 |
| 17. Oral and Maxillofacial Radiology | 6-10 |
| 18. Oral Microbiology | 6-10 |
| 19. Dental Public Health & Epidemiology | 6-10 |
High-Yield Domain Snapshots
Beyond the "big three," a cluster of mid-weight clinical domains (6-10 questions each) forms the backbone of the rest of the paper. Master these and you cover the majority of remaining marks.
Domain 12: Oral Surgery
Exodontia decision-making, complications, and post-operative management scenarios delivered as single-best-answer clinical vignettes.
- Indications and contraindications for extraction
- Management of common surgical complications
Domain 11: Orthodontics
Recognition of malocclusion classifications and appropriate referral timing rather than appliance design detail.
- Index of Orthodontic Treatment Need thresholds
- Age-appropriate referral pathways
Domain 17: Oral and Maxillofacial Radiology
Image interpretation and justification of radiographic choice under exposure-minimisation principles.
- Selecting the correct view for a clinical question
- Recognising pathology on periapical and panoramic films
Domain 8: Emergency Care (Management of Dental and Facial Injuries)
Immediate management sequencing for trauma presentations, including which interventions take priority.
- Avulsion and luxation management windows
- Red-flag signs requiring urgent referral
The smaller domains - Professional Knowledge and Behaviour, Patient-centred Care, and Teamworking - carry only 1-4 questions each but are frequently underprepared because candidates assume they're "common sense." A concentrated hour reviewing professionalism scenarios is a better return on time than another hour re-reading pharmacology you already know.

Building a Domain-Weighted Revision Timeline
A generic study calendar is useless if it ignores blueprint weighting. Instead, allocate weeks proportionally to question count, front-loading the domains worth the most marks and finishing with the smaller professionalism-focused domains, which are quick to revise close to the exam date.
Underpinning Clinical Knowledge (Domain 5)
- Drill pharmacology and applied physiology with timed SBA sets
- Build a rapid-recall sheet for drug interactions relevant to dentistry
Clinical Examination and Assessment + Diagnosis, Patient Management and Treatment Planning (Domains 6-7)
- Practice vignette-style questions that combine history, examination, and plan
- Time yourself to match the two-hour, 90-question pace
Mid-weight clinical domains (8-19)
- Rotate through Oral Surgery, Orthodontics, Radiology, Paediatric Dentistry, and Oral Medicine
- Use spaced repetition on weaker domains identified from mock scores
Professionalism domains + full mocks
- Review Domains 1-4 (Professional Knowledge and Behaviour, Patient-centred Care, Teamworking, Clinical and Patient Safety)
- Sit at least one full 180-question timed mock under exam conditions
If you're still assessing how demanding this exam is relative to your current knowledge base, the How Hard Is the MJDF Part 1 Exam? guide and the MJDF Part 1 Pass Rate 2026 data page both help calibrate expectations before you lock in a six-week plan like this one.
Mistakes That Cost Marks on Exam Day
- Mistiming the two papers: 90 questions in two hours leaves roughly 80 seconds per question - practice pacing on full-length mocks, not isolated question banks, at our practice test platform.
- Skipping questions instead of guessing: with no negative marking, an unanswered question is strictly worse than a guess.
- Ignoring the small domains: losing easy marks in Teamworking or Patient-centred Care because revision time went entirely to Domain 5-7 content.
- Underestimating radiology and microbiology: Domains 17 and 18 are easy to deprioritise but each carry 6-10 questions - a meaningful chunk when combined.
- Not rehearsing the break: the short break between papers is brief; plan it so it doesn't disrupt your focus for paper two.
Run a handful of timed sets on the main practice test site against this exact domain breakdown before you commit to a sitting date - matching your mock accuracy to the real 90-question, two-hour pacing is the single best predictor of exam-day comfort.
