Overseas Registration Examination · Part 2

ORE Part 2 has entered a new era

The new Consortium guidance changes how you prepare, perform and are assessed.

A complete summary and comparison of all 45 key changes across DTP, OSCE, Dental Manikin and Medical Emergencies — all four documents, structured for your ease and understanding. The guidance you have been revising from was written in 2017–2018. It has been replaced by Version 1.0, effective 1 March 2026.

The Arch ORE Part 2 courses are now in the pre-launch trial phase — the public launch is coming soon. This page is free to read and free to share: no sign-in, nothing to buy.

Applies to all four papers

Seven changes hit all four papers at once

Before you look at your own station: these seven apply to DTP, OSCE, Dental Manikin and Medical Emergencies alike. The framework you are measured against is no longer the one the old guidance named.

How you are marked

You are no longer assessed against Preparing for Practice. The framework is now The Safe Practitioner.

Was

The GDC's Preparing for Practice (PfP), revised 2015. Four domains: The Clinical Domain, The Professionalism Domain, The Communication Domain, The Management and Leadership Domain.

Now

The GDC's The Safe Practitioner: a framework of behaviours and outcomes for dental professional education — Dentist (SPF). Four domains: Clinical Knowledge and Skills, Interpersonal Skills, Professionalism, Self-management.

Why it matters: this is not a rename. "Communication" has become "Interpersonal Skills", and "Management and Leadership" has been replaced by "Self-management" — the domain that covers your own time-keeping, insight, and knowing your limits. In the OSCE the domains are now scored individually, so the wording is the mark scheme, not a preamble.

Worth knowing — the two documents disagree

The Examination Specification sitting on the same download page has not been switched over. It still says all ORE content "is mapped against the GDC Learning Outcomes… in the document Preparing for Practice (PfP)", and that the OSCE "will test the following four PfP domains: Clinical, Communication, Professionalism, Management and Leadership".

Follow the station guidance. It is the newer document (Version 1.0, effective 01/03/26), it is specific to your component, and it is what the examiners mark from. Treat the specification as useful for topic coverage and mark totals, not for the domain names. If the mismatch bothers you, the two frameworks cover much the same ground — the SPF simply cuts it differently.

How you are marked

A fifth grade — Borderline — has been inserted into the scale

Was — four levels

  1. Exceeds Standard
  2. Meets Standard
  3. Below Standard
  4. Well Below Standard / Not Done

Now — five levels (OSCE stations, DTP global)

  1. Exceeds Standard
  2. Meets Standard
  3. Borderline
  4. Below Standard
  5. Well Below Standard

Why it matters: the old scale forced an examiner who was undecided to round up or down. The new one lets them park you, and a parked candidate is then resolved by the standard-setting method — not by the examiner's gut. Medical Emergencies uses Clear Pass / Borderline Pass / Borderline Fail / Clear Fail as before, but the combination rule for those grades is new and brutal. See the ME section.

On the exam day

Watches are banned. So are smart devices and AI-enabled wearables.

Was

No equivalent rule in any of the four documents. The Manikin guidance described the clocks in the skills lab and the digital timer on your workstation monitor. The DTP guidance gave you a physical clock face and added that "your official examination time will be controlled by the helper with a stop watch" — but that if the clock malfunctioned, "it is your responsibility to monitor your own time use".

Now

Identical wording in all four: "Books, electronic devices (including smart devices and AI-enabled wearable technology), and watches are not permitted in the examination."

What to do: practise every timed exercise without a watch on your wrist. In the DTP you still get the colour-coded clock face; in the Manikin the room clocks are no longer described in the guidance at all, so do not build a plan that depends on glancing at your own watch.

On the exam day

Arrive on your allotted time. Late means you do not sit.

Was

Nothing in the guidance documents about arrival, identification, or lateness.

Now

Candidates arrive at an allocated time confirmed by email. Arrive early and you "may be asked to leave the building". Arrive late and you "will not be permitted to sit the examination". Reasonable adjustments must be requested at least six weeks before the date. Venues differ between diets — check the address on the email.

What to do: the six-week window for reasonable adjustments is the one with a hard deadline you can miss months in advance. Diarise it the day you book.

On the exam day

Two new sections in all four papers: Irregularities, and Examination Regulations

Was

The DTP guidance warned against copying or removing sheets. Otherwise nothing on reporting problems or on discussing the exam afterwards.

Now

Irregularities: anything outside your control that you believe harmed your performance must be reported to the delivery team as it happens and before you leave the venue. Regulations: discussing the examination before or after — including after you have left — is a breach.

What to do: if a handpiece fails, an actor goes off-script, or a station overruns, say so on the day. Walking out and complaining afterwards is now explicitly too late. And the recall groups people post in after the exam are, in the Consortium's own words, a breach of regulations.

On the exam day

Your examination may be recorded

Was

No mention of recording.

Now

"The examination may be recorded for quality assurance or training purposes." Stated in all four documents.

Why it matters: mostly it does not change what you do — but it does mean professionalism lapses in the room are reviewable after the fact rather than resting on one examiner's memory.

Confirmed unchanged

The "UK undergraduate" benchmark did not disappear — it moved

Was

Stated plainly in both the OSCE and Manikin papers. The Manikin's wording: "The competencies expected of a candidate to pass the ORE has been set by the GDC to be no better and no worse than that of a UK undergraduate passing their BDS exams." The OSCE said the same thing in slightly different words.

Now

The sentence appears in none of the four new guidance documents. But it survives, in stronger terms, in the Examination Specification for Candidates published alongside them: "Candidates are expected to meet or exceed the standard of a 'just passed' UK BDS graduate i.e. a minimally competent candidate." And: "All ORE examination content is pitched at the level of a minimally competent candidate."

Why it matters: when four documents drop a reassuring sentence at once it is easy to assume the bar has been raised. It has not. The standard is unchanged — it has simply been relocated from the station guidance into the specification that governs the whole exam, where it now applies to Part 1 and Part 2 alike. Aim at a safe, minimally competent UK graduate, exactly as before.

Paper 4 · 13 minutes

Medical Emergencies — three new conditions and a changed oxygen flow rate

The single highest-yield set of changes in the whole rewrite. If you revise nothing else from this page, revise this section: the model answers themselves have moved.

Session
13 min8 min oral + 5 min BLS — unchanged
Conditions
11 → 14stroke, sepsis, deteriorating patient added
Oxygen
10 → 15 L/minin the published asthma answer
Guidelines
2015 → 2025RCUK, plus Quality Standards
What you must learn

Three conditions added to the examinable list, and "fitting" is now "epilepsy"

Was

Eleven: anaphylaxis · shortness of breath incl. asthma and hyperventilation · swallowed/inhaled foreign body · collapse of unknown cause · vaso-vagal attack · post-operative haemorrhage · hypoglycaemia · fitting · acute onset chest pain · corticosteroid insufficiency · needlestick injury.

Now

Fourteen. The same list, with fitting renamed epilepsy, plus three genuinely new topics: stroke, sepsis, and deteriorating patients.

What to do: the three scenarios you draw come from a question bank built on this list, so your odds of drawing something you have never rehearsed just rose. Prepare FAST and the stroke pathway; sepsis — red flags and the recognition-to-999 route in a dental setting, which is why the new guidance now cites the RCUK Quality Standards; and the deteriorating patient, which is an ABCDE assessment question in disguise. Rehearse ABCDE out loud until it is automatic — it is the spine of all three.

What you must learn

Oxygen in the published asthma answer is now 15 L/min, not 10 L/min

Was

Model answer to "How will you manage this patient?": stop treatment and remove instruments · sit the patient upright · give their own medication (salbutamol) or salbutamol from the drug box, 4–6 activations via a spacer · Oxygen 10 L/min.

Now

Stop treatment and remove instruments · sit the patient upright · give the patient salbutamol · Oxygen 15 L/min.

What to do: say 15 L/min. This is the one number in the whole ME paper that has visibly moved, and it is in the only worked example the Consortium publishes. Keep saying "via a spacer" and "4–6 activations" — the detail has been dropped from the printed answer, but it is still correct practice and still scores.

What you must learn

Resuscitation guidelines: 2015 → RCUK 2025

Was

Assessed against the Resuscitation Council document Medical Emergencies and Resuscitation… in General Dental Practice including the 2015 update. "The September 2015 guidelines should be used in this assessment."

Now

"The 2025 resuscitation guidelines available on the Resuscitation Council UK (RCUK) website should be used in this assessment. These should be read in conjunction with the RCUK Quality Standards."

What to do: revise from the current RCUK site, not from a course handout dated 2015 or 2021. The Quality Standards reference is new in both places it appears and is where the sepsis and deteriorating-patient expectations live.

What you must learn

The pocket mask now has a one-way valve and a filter — and dropping them no longer voids your ventilations

Was

A "manufacture approved cross infection bio-filter" (the original's wording). If you removed it or did not use the mask, that was unsafe practice: "the candidate will not be allowed to ventilate, but asked to continue the exercise as if they had successfully delivered the ventilations. However, no marks will be awarded for the ventilations."

Now

A manufacturer-approved one-way valve and Technostat filter, both changed for each candidate. If you remove either, or do not use the mask, "the candidate will be advised to replace the valve and filter and asked to continue but will be marked down for this particular aspect. The rest of the exercise will be marked as normal."

What to do: the penalty has softened from losing the ventilation marks outright to being marked down on one aspect — but do not treat that as slack. Two components now have to stay in place instead of one, and mouth-to-mouth is still explicitly unacceptable in a healthcare setting. Handle the mask as an assembly: valve on, filter in, neither comes off.

How you are marked

You now need both examiners to pass you. One Borderline drags the whole scenario down.

Was

Two examiners marked independently and each graded every question. How their two grades combined into a scenario outcome was not published.

Now

Published in full: "A Pass is awarded only where both examiners award a Pass. A Borderline outcome is awarded where one examiner awards a Pass and the other awards a Borderline. All other combinations, including two Borderline grades or any combination containing a Fail, result in an overall Fail."

Why it matters: two Borderlines is a fail. There is no averaging up. Unchanged and still decisive: the three scenarios and the BLS carry equal weight, there is no compensation between them — you must pass the scenarios and the BLS separately — and there is compensation between the three scenarios.

How you are marked

Both examiners now question you. There is no silent one taking notes.

Was

"As the first assessor is asking the structured questions, their colleague will be making notes on the performance of the candidate. This should reverse when the second assessor begins to ask questions." Each theme carried 5 questions.

Now

"There will be two examiners marking each candidate and both examiners will ask structured questions. During the assessment, they will independently award marks and make notes." Each theme now carries "a number of questions" — no count is published.

What to do: stop budgeting your eight minutes as five-questions-times-three. The count is no longer fixed, so pace by clock, not by question. And you are being marked by whoever is speaking as well as whoever is not — address both examiners.

What you must learn

The published asthma answer swapped its numbers for descriptions

Was

Acute severe: inability to complete sentences in one breath · respiratory rate >25/min · tachycardia (heart rate >110/min).
Life-threatening: cyanosis · respiratory rate <8/min · bradycardia (heart rate <50/min) · exhaustion · confusion · decreased conscious level · inability to complete full sentences.

Now

Acute severe: inability to complete sentences in one breath · increased respiratory rate · tachycardia.
Life-threatening: cyanosis · poor respiratory effort · reduced heart rate · exhaustion · confusion · altered conscious level.

Do not read this as permission to drop the numbers. The examiners are told to reward answers that centre on clinical management, and a candidate who says "respiratory rate above 25, heart rate above 110" has given the description and the threshold. Keep the figures; just do not be thrown if the examiner accepts the qualitative answer from the person before you.

On the exam day

Nobody will tell you when you are halfway through

Was

"The administrator will indicate when half the examination is completed." Manikins were tested by the examiners "every six candidates".

Now

The halfway call is gone from the guidance. Manikins are now tested "regularly" rather than on a stated interval.

What to do: with no halfway prompt and no watch on your wrist, the 8-minute oral and the 5-minute BLS have to be paced by rehearsal. Practise BLS to a five-minute timer until the shape of it is muscle memory.

Confirmed unchanged

The shape of the paper is exactly as it was

Was

13 minutes: 8-minute structured oral on three scenarios from an agreed bank, then 5 minutes of single-handed BLS on an adult or child, including the AED.

Now

Identical. Three scenarios, themes chosen by the lead examiner, concise answers expected, no prompting and no rephrasing of questions, time-limited exercises still carry marks for finishing inside the time. A mark for communication and professionalism is still recorded.

Reassurance: your rehearsal structure survives intact. It is the content list, the oxygen figure, the guideline year and the mask that moved.

Paper 2 · circuit

OSCE — shorter, smaller, and marked a completely different way

The most structurally rewritten of the four. The circuit has shrunk, pilot and double stations are gone, and the marking has moved from adding up percentages to Borderline Regression against the SPF domains.

Duration
2½h → 2ha single continuous session
Stations
up to 24 → 2015 live + 5 rest, fixed
Each station
6 min1 min reading + 5 min task
Grades
4 → 5Borderline inserted
Marks
16 × 15 = 240per the Exam Specification
What you must learn

Open every station by stating your name and candidate number

Was

No such instruction. You were handed an empty folder at the start of the circuit and collected answer sheets as you went.

Now

"Candidates should begin each station by confirming their name and candidate number."

What to do: this is the cheapest instruction in the entire rewrite and the easiest to forget under pressure at station 11 of 15. Bolt it to the front of your station routine now, in every practice run, so it survives the day: name, candidate number, then greet the patient.

What you must learn

New: you may be asked "What would you like to examine?" — and you must answer in two parts

Was

Nothing on clinical examination technique. Stations were described only as testing "assessment of a patient" and "simple practical procedures".

Now

A dedicated Clinical examination section. You are expected to carry out basic examinations and to identify and use the appropriate equipment. Professional behaviour must match real practice, "including requesting permission to perform any relevant clinical examinations". Some stations require you to perform it; in others the examiner asks "What would you like to examine?" — you must specify the examinations and, where relevant, explain how you would perform them. The examiner then hands you a results sheet.

What to do: rehearse naming examinations out loud in a fixed order — extra-oral, intra-oral soft tissues, hard tissues, periodontal, occlusion, special tests — with a one-line method for each ("I'd palpate the submandibular and cervical nodes bilaterally from behind"). Naming it is half the mark; describing the method is the other half. And ask permission every time: it is now written into the guidance, not implied.

How you are marked

Every station is now scored on three named SPF domains plus an overall judgement

Was

"Each station is individually marked against structured criteria and carries equal weight." Total points and pass points varied per station. Role players might allocate marks for communication.

Now

"Each station will be assessed against three of the following four domains, depending on the station's focus": Clinical knowledge and skills · Interpersonal skills · Professionalism · Self-management. Examiners give "a judgement for each of the three domains assessed, as well as an overall judgement for the station".

What to do: a technically perfect station can now be marked down on a domain you did not realise was live. Before each practice station, ask which three domains it is testing. A consultation station is almost certainly clinical + interpersonal + professionalism; a station where you must finish inside five minutes and know when to stop is testing self-management.

How you are marked

Marking method: aggregated percentages → Borderline Regression

Was

"The percentage marks from each active and contributing OSCE station will be aggregated to provide an overall mark." And explicitly: a fail in one active station "will not necessarily be an automatic fail for the OSCE component as the aggregated marks of all the active stations are used".

Now

"The OSCE uses the Borderline Regression method of standard setting to establish a cut-off score for each station. Candidates' numerical scores are then used to determine both their station-level results and overall OSCE outcome, which are classified as Pass, Borderline, or Fail."

The numbers behind it, from the Examination Specification published on the same page: 16 marks per station, 240 marks in total across the 15 live stations. Read this carefully: each station now has its own cut-off, derived from how the examiners graded the candidates they judged borderline. The old sentence reassuring you that one bad station would not sink you has been removed, and the new document does not state a replacement compensation rule either way. Do not assume you can write off a station.

On the exam day

Twenty stations, fixed. Pilot stations and double stations are gone.

Was

A circuit of up to 24 stations, of which "at least 15" were active, plus rest stations and pilot stations that trialled future exercises and did not count. There could be 1 or 2 double stations combining two slots to probe a domain in greater depth. Up to three circuits ran per day. Sessions ran up to 2½ hours.

Now

"Each OSCE circuit consists of 20 stations, 15 of which are live, and five of which are 'rest' stations." Live stations count; rest stations are "an opportunity for candidates to reflect". Every station is six minutes. The session is up to two hours. No pilot stations, no double stations, no stated circuit limit per day.

What to do: the maths is now knowable — 15 stations that all count, 5 breaks, 20 × 6 = 120 minutes. Every station you walk into is scored, so the old habit of wondering whether one was a pilot is dead. Build your practice circuits as 15-of-15.

On the exam day

The folder and the colour answer sheets have gone

Was

"Candidates will be issued with an empty folder at the beginning of the session. As they pass through the unstaffed stations they will collect and complete answer sheets, put them in the folder which will be collected by administration staff." You were forbidden from using rest stations to complete paperwork.

Now

No folder, no unstaffed-station mechanic. "The OSCE is a timed clinical examination in which candidates will move from station to station… Most stations will also involve interaction with a simulated (standardised) patient." Written stations still exist as one of four station types.

What to do: the circuit is now overwhelmingly face-to-face rather than a mix of manned and paper stations. Weight your preparation accordingly — more talking, less silent form-filling.

How you are marked

Nine skill categories replaced by four station types

Was

Stations tested "different skills or combinations of skills such as": history taking · assessment of a patient · simple practical procedures · communication · patient education · clinical judgment · decision making · ethics · professional attitude. Actor stations tested history, needs, options, consent, oral health education, radiographic interpretation and prioritising treatment.

Now

A non-exhaustive list of four station types: Consultation station · Station including a physical examination · Written station · Skills demonstration.

What to do: the old list told you what was tested; the new one tells you what the room looks like. The skills have not disappeared — they have been folded into the domains. Prepare by station type, and score yourself by domain.

What you must learn

The published example changed from a consent script to an open consultation

Was

Mr/Mrs Green, referred for extraction of a carious LL7, fit and healthy, never extracted before — explain the treatment so the patient can give informed consent. Published with the full examiner mark grid: introduces self (name & designation) · avoids jargon · discusses the problem, the procedure, the options, no-treatment, side effects · invites questions · plus two role-player items on sympathy and understanding.

Now

"You are a BDS graduate working in a general dental practice… assess and manage a 23-year-old patient who has presented with a toothache. You are not given any additional information." Domains assessed: clinical knowledge and skills, interpersonal skills, professionalism. What is required to pass: thorough history (presenting complaint, dental history, basic relevant medical history) · appropriate lifestyle/social history · identify the patient's concerns, listen, display empathy · make a diagnosis · recommend appropriate management and follow up · professionalism throughout.

What to do: the example has moved from a scripted explanation to a cold-start consultation where you must reach a diagnosis and a follow-up plan inside five minutes. The old published mark grid is gone, so those eight rows are no longer a checklist you can drill — but the behaviours in it still map onto interpersonal skills and professionalism. Practise the toothache consultation to a five-minute timer and finish with a named diagnosis, a plan, and a review interval.

On the exam day

The "stay for the full five minutes" rule is no longer written down

Was

"Candidates must stay in the station for the full 5 minutes even if they complete the task in less time. An automatic timing system will sound when it is time to move on."

Now

Neither sentence appears. The guidance says only that stations are "six minutes long in total: one minute reading time at the beginning and five minutes to complete the task".

Do not misread this. Nothing says you may now leave a station early, and with a fixed 20-station circuit everyone still moves together. Treat the five minutes as yours to use: if you finish, check your work, offer the patient a chance to ask questions, or summarise. Walking out early has never scored anything, and the removal of the sentence does not change that.

Paper 1 · 54 minutes

DTP — same clock, new marking, and a video you must watch beforehand

Good news first: the 54 minutes and the 10 / 11 / 23 / 10 split are untouched, and so are the colour-coded forms. What changed is how you are scored, one extra thing you must produce, and a large amount of practical advice that has simply been deleted.

On the exam day

There is now a DTP Guidance Video — and it will not be played on the day

Was

No video. You were collected from a holding area, taken to one of four or five DTP areas, and handed a clock and a folder with your candidate number.

Now

"This guidance should be read in conjunction with the DTP Guidance Video ahead of the examination. The video will not be shown on the day." The document does not say where to find it. It is on the ORE Part 2 site, on its own page, free and with no login.

Where it is: orepart2.org.uk/dtp-guidance-video — linked from the Guidance page as "DTP Guidance Video (watch before attending the DTP exam)". It is a self-hosted MP4, no sign-in needed. This is the only place in the four documents where the Consortium points at required preparation outside the PDFs, and it explicitly closes the door on catching up at the venue.

What you must learn

Stage 3 now asks for a definitive diagnosis, not just a treatment plan

Was

Stage 2 produced a written provisional (possible) diagnosis. Stage 3 was: consider the artefacts, "formulate a treatment plan and write down the treatment options and their advantages and disadvantages", plus the radiographic report. No second diagnosis was requested.

Now

Stage 3, first bullet: "Formulate a definitive diagnosis" — then produce the written treatment plan, consider alternatives, identify risks, benefits and limitations, consider patient wishes, prognosis and long-term maintenance, justify referrals, and complete the radiographic report.

What to do: once the special investigations and radiographs come back, explicitly revise your provisional diagnosis into a definitive one and write it down. Candidates trained on the old paper go straight from artefacts to treatment options and never state the diagnosis a second time. That is now a named expectation.

How you are marked

Five graded areas, plus a separate global judgement on a five-point scale

Was

Graded in five areas — oral history · provisional diagnosis, special investigations, radiographic request and report · contemporaneous notes · written treatment plan · oral treatment plan — each on four levels (Exceeds / Meets / Below / Well Below or Not Done). "The percentage marks from the five areas of assessment will be aggregated to provide an overall mark which will be used to determine whether a candidate has passed or failed."

Now

The same five areas, each on the four-level scale — and in addition "examiners will give a global judgement" on five levels: Exceeds Standard · Meets Standard · Borderline · Below Standard · Well Below Standard. "The DTP uses the Borderline Regression method of standard setting to establish a cut-off score for each scenario," and the outcome is Pass, Borderline, or Fail.

Why it matters: the global judgement is a whole-performance impression that sits alongside the five itemised areas — so a candidate who ticks boxes without ever looking like a safe clinician can be marked down on the overall view. Aim for a coherent consultation, not five separately-optimised sections.

What you must learn

The radiographic report specification has been deleted — but you still have to write the report

Was

Section 5.6 spelled it out: "Your report should be the standard expected by the GDC and should include which film view it is, details of the side, bone quality, bone level, teeth present, restorations or caries present, and any other relevant details. Finally you should comment on the quality, and any issues related to the film itself." Plus: "You should use the real radiograph to make the report and not the one illustrated on the sheet."

Now

Stage 3 says only: "Complete a written radiographic report for a designated radiograph." All six sections of form-by-form advice (5.1 to 5.6) have been removed from the document.

This is the single most valuable thing on this page. The task has not changed — only the guidance that told you how to pass it. Use the old specification as your report template anyway: view · side · teeth present · bone level and quality · restorations · caries · other findings · film quality and faults. And keep reporting from the real radiograph, not the printed thumbnail on the form.

What you must learn

The cost guidance has gone. So has the artefact-checking instruction.

Was

"In view of the difficulty of understanding costs of treatment in a foreign country you will not be expected to give indication of costs other than the relative difference of any treatment recommended e.g. implants high cost relative to denture." And: "it is your responsibility to check that all the artefacts are present. There is a list on the top of the artefacts… If you believe the artefacts do not agree with the list please contact the helper immediately."

Now

Neither statement appears. Cost is not mentioned anywhere in the new DTP document. The artefact checklist is not mentioned either — Stage 2 simply says candidates "will review the clinical information and artefacts provided".

What to do: the exemption from quoting costs is no longer written down, so handle cost the safe way — relative, never absolute ("an implant is considerably more expensive than a denture"). And check your artefacts against what you were told to expect regardless; the instruction has gone, the risk of a missing cast has not.

How you are marked

Two examiners are now stated to be present for history taking

Was

The summary listed "Oral History assessed by 2 examiners", but the walk-through said: "When you are taken to your chair you will find an examiner and your patient… An examiner, who will remain mainly silent during this part, will observe you."

Now

Stage 1, unambiguously: "Candidates will be seated with a simulated (role-player) patient and two examiners." Assessment focuses on history-taking skills, communication skills, professionalism, and the quality and accuracy of contemporaneous notes.

What to do: expect two people watching you take the history, and do not let a silent second examiner unsettle you. Everything else in Stage 1 is unchanged, including the rule that you may not examine the patient or their mouth.

What you must learn

The special-investigations examples have been trimmed

Was

Vitality tests · full mouth periodontal charting · body temperature · condition of muscles of mastication · cracked tooth tests.

Now

Vitality testing · additional periodontal assessment · body temperature measurement · assessment of muscles of mastication. Cracked tooth tests no longer listed.

What to do: both lists are explicitly non-exhaustive, so nothing is forbidden. Keep requesting a cracked tooth test when the history points at one — but justify it, because the guidance still insists you request "only investigations relevant to diagnosis and treatment planning", and an unjustified shopping list has always cost marks.

What you must learn

The published scenario is the same case, stripped of half its detail

Was

An unnamed patient, DOB 17/12/49, with a full actor brief: tooth wear, missing posteriors, lost crown on the upper right lateral, a lower denture broken three years in and thrown away, gagging history, anxious personality. Medical: hypertension on atenolol 50 mg, atorvastatin 10 mg, bendroflumethiazide 25 mg, omeprazole 20 mg. Social: non-smoker, 12 units a week, several cans of cola daily, clenches when stressed. Artefacts included slight loss of vertical height ~2 mm with a similar increase in freeway space, and soft dentine on the 12.

Now

"Mrs Smith, aged 59 years. 32 High Field, Cambridge, CB1 1LZ." Patient scenario: "The patient is concerned about the wear of her front teeth and the loss of some teeth and a crown." Same clinical picture retained: fair OH with plaque and lingual calculus, bleeding on probing, BPE 2/2/– over 2/2/2, generalised recession, Class II div 1, generalised horizontal bone loss, no active caries but poorly shaped restorations, no mobility, OPT and periapicals. The gagging history, the vertical height loss and the soft dentine on the 12 are not in the published version.

What to do: practise on this exact case — it is the Consortium's own worked scenario and the clinical core is unchanged. But treat the old, fuller version as the better rehearsal: the medication list, the cola habit, the clenching and the gagging history are precisely the things a good history extracts, and the examiner's role-player brief will still contain material the printed example does not show you.

Confirmed unchanged

The clock, the four stages and the colour-coded forms are untouched

Was

54 minutes: history and contemporaneous notes 10 · provisional diagnosis, special investigations and radiographic prescription 11 · written treatment plan 23 · presentation to the patient 10. White candidate info, blue history, orange diagnosis/prescription/investigations, green report and treatment plan. Individual clock face supplied.

Now

Identical — same four stages, same minutes, same four colours, same clock face in Appendix 1. All documentation still submitted at the end, and "failure to submit required forms may affect the marks awarded".

Reassurance: every timing drill you have already done still applies. Do not rebuild your DTP practice — extend it.

What you must learn

Stage 4 now has a published six-point structure — including "explain the diagnosis"

Was

Prose: present the plan "in lay terms explaining your essential findings in such a way that the patient has sufficient information to understand the advantages and disadvantages of the possible options… and to give valid consent for your proposed preferred option". Plus care, prevention and the influence of medical problems.

Now

A list. Candidates are expected to: explain the diagnosis and findings · discuss available treatment options · explain the advantages and disadvantages of each · recommend a preferred option · discuss risks, preventive measures and maintenance requirements · answer questions from the patient and examiners.

What to do: use these six as your running order in the last ten minutes — they are effectively a mark sheet the Consortium has published. Two are easy to drop under pressure: opening with the diagnosis (candidates jump straight to options), and maintenance (they cover risks but forget review and upkeep).

What you must learn

The written treatment plan must now contain five named elements

Was

"…enter the treatment and care options… This should include any urgent, immediate and planned treatment as well as long term care plans together with your preferred treatment… You should also indicate any risks of the proposed treatment."

Now

"The treatment plan should include: immediate or urgent treatment · definitive treatment · preventive advice and maintenance requirements · alternative treatment options with advantages and disadvantages · referral arrangements where appropriate."

What to do: the substance is close to the old wording, but it is now five explicit headings — so write your plan under those five headings. It costs nothing, it guarantees you cannot omit one, and it makes the marker's job trivial. "Preventive advice and maintenance" is the heading candidates most often leave blank.

Paper 3 · three hours

Dental Manikin — two brand-new exercises, and one moved lining

Start with the headline that will save you a week of panic: every millimetre specification that existed in the old guidance is unchanged. Nothing has been re-cut. What has happened is that two exercises have been added, one lining has moved, the instrument tray has been rebuilt, and the entire exam-day briefing section has been deleted from the document.

Session
3 hours2 major + 1 minor exercise

New taper
8°–12°all-ceramic only

The one-line summary

If you have already learnt the old preparation dimensions, keep them. Then add two exercises you have never seen, and check which instruments have left your tray.

Important points to know about your Manikin exercises

Everything at exercise level that moved, in one place. Nothing else in the preparation specifications changed.

  1. A lining moved. On the Class I occluso-palatal cavity the thin lining now goes on the axial wall, not the pulpal floor. One word in a table, and the only change in the whole paper that moves where you physically place material.
  2. Class II in composite is new. It existed only in amalgam before. Box dimensions are the same, but the technique is marked: composite must be placed in increments of no more than 2 mm, and voids and excess on the margin are named undesirable features.
  3. All-ceramic crown preparation is new. Two materials, two specifications. The taper is 8°–12° — not the 6°–20° you learnt for gold and metal-ceramic. e.max is given as ranges; zirconia is given a 1.0 mm minimum and no maximum, so treat 1.0–1.5 mm as your ceiling. No feather or knife edge on zirconia.
  4. Class II amalgam says “box or boxes”. The caries may be mesial, distal or both, so rehearse the MOD to the same standard as a single-box MO.
  5. The instrument tray changed. The gingival margin trimmer is gone, along with the American pattern probe, the ball burnisher and the flat fissure steel burs. If your Class II gingival floor technique depends on a GMT, rebuild it. You gain a second excavator, a Williams 14W and a ruler.
  6. Every other dimension is unchanged. Class I depth ~2 mm, Class II contact clearance ~0.5 mm, Class V 2.5–3.0 mm wide, root filling 0.5–1.0 mm short of the apex, gold crown 1 mm occlusal and 6°–20°, veneer 0.5–0.7 mm labial, rest seats 0.75–1.0 mm deep. Not one figure was re-cut.
  7. “Exceeds Standard” got easier. It was “fulfils all of the desirable criteria”; it is now “fulfils all, or nearly all”. That matters, because an Exceeds in a major exercise is what buys you compensation elsewhere — and an Exceeds in the minor exercise buys you none.
  8. You still must pass Exercises and Safe Practice separately. Land in the borderline range and every examiner on the day reviews your work independently, and the outcome becomes a plain Pass or Fail.
What you must learn

New exercise: all-ceramic crown preparation, with two different material specifications

Was

Two crown preparations only: full gold veneer crown and metal ceramic crown. No all-ceramic exercise existed in the guidance.

Now

A third: "Prepare the tooth indicated to receive an all-ceramic crown", specified separately for IPS e.max CAD blocks and monolithic zirconia. Index sectioned once in the middle of the tooth, as before.

All-ceramic crown — the new dimensions. Read the last column carefully: e.max is given as ranges, zirconia only as a floor.
FeatureIPS e.max CADMonolithic zirconiaLimits given
Occlusal / incisal reductionAnterior 1.5–2.0 mm incisally
Posterior 1.5–2.0 mm functional cusps

Not in the guidance — how much is too much?

You spotted the gap correctly: for monolithic zirconia the Consortium gives a minimum and no maximum. That is not permission to cut deeper. On the very same page, the Undesirable Features list — which covers both materials — marks down "too great … reduction occlusally/incisally" and "too great … axial reduction". So a ceiling is being marked; it simply is not given a number.

A defensible working band, and what we would teach: treat 1.0–1.5 mm as the ceiling for monolithic zirconia, occlusally and axially. It matches e.max's own stated axial range, it is what the material actually needs, and beyond it you gain nothing while losing resistance and retention form and moving toward the pulp.

If an examiner asks you to justify a figure: say that zirconia's strength lets you preserve tooth tissue, so you prepare to the minimum the material requires and no further — 1 mm is the floor, and tooth tissue is not recoverable. That answer is defensible whatever number they have in mind.

e.max needs no such judgement: its figures are already ranges, so the ceiling is stated — 2.0 mm incisally and on functional cusps, 1.5 mm on non-functional cusps, 1.5 mm axially.

Table scrolls sideways →

What to do: learn these as a separate set — do not carry over the gold-crown numbers. Three things catch people: the taper is tighter (8°–12°), zirconia needs far less reduction than e.max, and zirconia explicitly forbids a feather or knife edge. Path of insertion and surface finish requirements are the same as the other crowns.

What you must learn

New exercise: Class II in composite — with a 2 mm increment rule

Was

Composite exercises were Class III, Class IV, Class V and a fractured-cusp build-up. Class II existed only as an amalgam exercise.

Now

A Class II composite in an upper posterior tooth. Cavity design is a "proximal box or boxes… with some extension along the fissure as appropriate" and a smooth cavity outline. The completed restoration: "Composite to be placed increments of no more than 2mm deep" (sic), manipulated to restore the lost marginal ridge and occlusal anatomy, with a tight proximal contact and a smooth surface finish.

What to do: box dimensions match the amalgam Class II — gingival floor clearing the contact by ~0.5 mm, bucco-palatal clearance ~0.5 mm, occlusal lock ~2 mm deep. What is new is the technique marking: incremental placement in ≤2 mm layers, and the undesirable list now includes voids present and excess left on the margin or interproximally. Practise placing and curing in visible increments where an examiner can see you doing it.

What you must learn

Class I occluso-palatal: the lining moved from the pulpal floor to the axial wall

Was

Occluso-palatal cavity, item 5 — Lining: "Thin layer applied to the pulpal floor (if applied)".

Now

Same exercise, item 5 — Lining: "Thin layer applied to the axial wall (if applied)".

What to do: this is the only desirable-feature wording in the whole Manikin paper that changes where you physically put material, and it is one word buried in a table — which is exactly why it is worth knowing. The depth and width figures for this cavity are unchanged: ~2 mm deep, ~1.5 mm wide, parallel walls with rounded internal line angles.

How you are marked

Exceeds Standard has been softened from "all" to "all, or nearly all"

Was

Exceeds Standard — Clinical work: "fulfils all of the desirable criteria specified for that stage of the test."

Now

Exceeds Standard — "Fulfils all, or nearly all, of the desirable criteria specified for that stage of the examination."

Why it matters: the top grade is now reachable without perfection, which matters because an Exceeds in a major exercise is what buys you compensation elsewhere. Meets, Below and Well Below keep their old definitions almost word for word — except that Well Below has dropped the line about the candidate being "unaware of the poor performance".

How you are marked

The compensation rule is now published — and the minor exercise cannot rescue a major one

Was

"The two major exercises carry twice the weight of the minor exercise. The overall result… is determined by aggregating the marks from each, with this weighting incorporated." How that played out in practice was left to inference.

Now

Same weighting, then stated outright: "an Exceeds Standard in a major exercise will compensate for a Below Standard in any exercise, however an Exceeds Standard in a minor exercise will not compensate for a Below Standard in a major exercise." Exercises and Safe Practice are each classified Pass, Borderline or Fail. Where a candidate falls in the defined borderline range, "their work is reviewed independently by all the examiners on the day" and the final outcome is Pass or Fail.

What to do: spend your time proportionally. A brilliant minor exercise is worth far less than a solid major one, and if you must let something slip, it cannot be a major. Unchanged and still absolute: you must pass the Exercises and Safe Practice sections separately.

What you must learn

The instrument tray has been rebuilt — the gingival margin trimmer is gone

Was

Mirror No 5 · straight probe No 6 · Thymoxin probe · Williams probe · American patterned probe No 3 · college tweezers · excavator 129/30 · flat plastic 156 · enamel hatchet No 53 + 54 · gingival margin trimmer U1/U2 + U3/U4 · amalgam plugger G · Mortensons plugger · Hollenbach carver · ball burnisher · pencil · scalpel No 11 · spatula · ruler · suture scissors. Slow-handpiece steel burs included flat fissure 1 and 4.

Now

Mirror handle + front surface No 5 · probe 6 · excavator 129/130 and 123/124 · chisel Hu-Friedy CP 53/54 · plastic filling instrument Hopson 156 · burnisher 1L · amalgam plugger G · Mortonson 2 · Hollenbach 3 carver · college tweezers · spatula No 3 · straight serrated scissors · Thymozin No 2 · Williams 14W perio probe · retractable disposable scalpels No 11 · 6-inch metal slim ruler · pencil. Slow-handpiece steel burs: rose heads ½, 1, 3, 5, 8 — flat fissures no longer listed. Added: "additional burs will be provided on the day when necessary."

What to do: if your cavity technique depends on a gingival margin trimmer to finish the gingival floor of a Class II box, rebuild it now — the instrument is not on the published tray. Same for the American patterned probe, the ball burnisher and the flat fissure steel burs. You gain a second excavator, a Williams 14W and, usefully, a ruler. The high-speed bur list is unchanged: tungsten carbide 170, 330, 331, 331L, 56, 557 and diamonds L767C, L767VF, 170L, 260.8F, 120C, 285.5VF.

On the exam day

The entire exam-day briefing section has been deleted from the document

Was

Two full pages of practical rules: the practice tooth marked with a black cross · check the teeth for manufacturing marks before the start, because after the start any damage is yours · "If you prepare the wrong tooth or wrong side of the tooth, this will be noted in your Safe Practice, and will impact heavily upon your marks" · raise a hand and ask a nurse, never wave at examiners · clocks called out roughly hourly, digital timer on your monitor · no breaks, water fountain available · examiners saying "fine, OK, good" is not feedback · stop immediately when time is called or lose professionalism marks · put the burs back · white coats optional, aprons provided · shoes covering the whole foot, no excessive heels · tell the nurses if you are pregnant or on special medication · gloves, masks and eye protection must be worn · a pre-operative radiograph is provided for the root canal test.

Now

None of it appears. The new document covers the briefings, the practice session, the request-and-assess loop with the examiners, and the operating position — and then moves straight to marking.

Read this carefully: nothing published says these practices have stopped. A skills lab still runs on hand-raising, still calls time, and still expects covered shoes. Treat the whole of the old list as live working practice — because the two items with real marks attached, preparing the wrong tooth and failing to stop when time is called, both still map onto Safe Practice and Professionalism, which are still separately assessed and still capable of failing you on their own.

What you must learn

Class II amalgam now says the caries may be mesial, distal, or both

Was

"Prepare a Class II cavity in the tooth indicated to correspond to the caries shown on the accompanying radiograph." Cavity design: "A proximal box and occlusal lock."

Now

"…The caries may be located mesially, distally or on both sides of the tooth." Cavity design: "Proximal box or boxes and occlusal lock."

What to do: the old paper already warned that a Class II "could be an MO or a DO or an MOD", but the instruction line now says it too. Rehearse the MOD — two boxes, two matrix considerations, one occlusal lock — to the same standard as a single-box MO. All box dimensions are unchanged.

Confirmed unchanged

Operating position, finger rests and infection control are word-for-word the same

Was

Sit upright, back supported, bottom to the back of the stool, thighs parallel to the floor, feet flat, neck slightly flexed. Manikin torso flat and parallel to the floor, occlusal plane of the upper arch vertical to force indirect vision. Operate between ten-thirty and one-thirty. Pencil grip near the handpiece head. Finger rest in the same arch, same side as the tooth. Palm grip permitted for chisels but always with a finger rest. Two permitted infection-control breaches: lowering the mask to be heard, and picking up a dropped instrument with explicit agreement.

Now

Identical in substance, restated as a Safe Practice section — "Safe Practice is assessed independently". Same posture, same vertical occlusal plane, same 10:30 to 1:30 range, same finger-rest rules, same two permitted breaches.

Reassurance: the Safe Practice grade descriptors are also unchanged — Exceeds means appropriate position, correct finger rest and full infection control; Meets tolerates occasional lapses; Below and Well Below describe frequent lapses continuing "despite repeated warnings by the examiners".

Nine things to change in your revision this week

Ordered by how much damage getting them wrong would do on the day.

  • Learn stroke, sepsis and the deteriorating patientThree new Medical Emergencies topics, drawn from the same question bank as the eleven you already know. ABCDE is the spine of all three.
  • Change your oxygen answer to 15 L/minThe only figure in the Medical Emergencies paper that visibly moved — and it sits in the Consortium's own published model answer.
  • Learn the all-ceramic crown dimensions as a separate setTaper 8°–12°, not 6°–20°. e.max is given as ranges; zirconia is given as a 1.0 mm minimum with no maximum — treat 1.0–1.5 mm as your ceiling, because "too great reduction" is still an undesirable feature. No feather or knife edge on zirconia.
  • Add "name and candidate number" to the front of every OSCE stationWritten into the new guidance, absent from the old, and the easiest thing in the world to forget at station 11 of 15.
  • Rehearse "What would you like to examine?"Name the examinations in a fixed order, say how you would perform each, ask permission. The examiner then hands you a results sheet.
  • Practise Class II in composite, placing visible ≤2 mm incrementsA Class II composite did not exist as a Manikin exercise before. The increment rule is written into the desirable features.
  • Keep using the old DTP radiographic report templateView, side, teeth present, bone level and quality, restorations, caries, other findings, film quality. The task survived; only the instructions were deleted.
  • Drop the gingival margin trimmer from your Class II techniqueIt is no longer on the published Manikin instrument tray. Nor is the American patterned probe, the ball burnisher, or the flat fissure steel burs.
  • Watch the DTP Guidance Video before the dayNew, required alongside the written guidance, and explicitly not shown at the venue.

Differences of spelling, punctuation, section numbering and re-ordering have been deliberately left out. Where a rule has been removed from the new guidance, this page says so and does not claim the underlying practice has stopped — read those entries as "no longer written down", not "no longer applies". Quotations are from the guidance documents themselves. All five documents, and the DTP Guidance Video, are free at orepart2.org.uk/guidance. Always check the current documents there before your diet, and treat this page as a study aid rather than a substitute for them.
