## What is the LDS Part 2 OSCE, and how do you practise for it?

The Royal College of Surgeons of England (RCSEng) Licence in Dental Surgery (LDS) Part 2 examination for dentists seeking UK General Dental Council registration, pitched at the standard of a newly qualified UK dental graduate (Safe Beginner under GDC Preparing for Practice). MedMock practises eight spoken station types across the LDS Part 2 components: five 5-minute OSCE stations (History & Information Gathering, Communication, Consent & Explanation, Breaking Bad News, Ethics & Candour, Paediatric Consultation, and Prescribing, Therapeutics & Cross-Infection Viva), the two Diagnostic and Treatment Planning (DTP) stages (13-minute Patient History and 15-minute Examiner Oral), and the 15-minute Medical Emergencies in Dental Practice Viva. MedMock lets you practise it out loud against an AI patient, with examiner-style feedback on any station you finish.

## What happens in the real LDS Part 2 (checked against the official source on 2026-10-24)

The Licence in Dental Surgery (LDS RCS) Part 2 of the Royal College of Surgeons of England is the clinical examination leading to the diploma of LDS RCS Eng, which confers eligibility for full registration with the General Dental Council. Held in London for candidates who have passed LDS Part 1, it assesses Safe Beginner competence across four components: an operative test on a dental manikin, an Objective Structured Clinical Examination (OSCE), a Diagnostic and Treatment Planning (DTP) exercise, and a Medical Emergencies (ME) examination.

- **Operative test on a dental manikin** (180 minutes): Three-hour practical operative dental examination on a phantom head manikin assessing cavity preparation, restorative procedures, endodontic access and crown preparation.
- **Objective Structured Clinical Examination (OSCE)** (5 minutes): A circuit of 5-minute OSCE stations (after reading time) assessing patient history taking, clinical communication, informed consent, breaking bad news, ethics, dental prescribing, radiography legislation and cross-infection control.
- **Diagnostic and Treatment Planning (DTP)** (28 minutes): A two-stage clinical assessment comprising a 13-minute history consultation with a simulated patient followed by a 15-minute structured oral with two examiners reviewing radiographs, charting and phased treatment planning.
- **Medical Emergencies in dental practice (ME)** (15 minutes): A 15-minute structured viva and practical assessment of the diagnosis and emergency management of acute medical collapses in the dental surgery alongside basic life support and airway management.

Marking: Each of the four LDS Part 2 components is marked separately against the GDC Preparing for Practice Safe Beginner learning outcomes and RCS England assessment regulations.

Passing: Candidates must pass every component of the LDS Part 2 examination at the standard of a newly qualified UK dental graduate. Candidates are permitted a maximum of four attempts at LDS Part 2 within five years of passing LDS Part 1.

## How to prepare for the LDS Part 2 (facts checked against official sources on 2026-10-24)

Read the Royal College of Surgeons of England LDS Part 2 regulations and the GDC Preparing for Practice outcomes first so you understand all four components. Then rehearse the 5-minute OSCE stations, the 13-minute and 15-minute Diagnostic and Treatment Planning stages, and the 15-minute Medical Emergencies viva out loud to time.

1. **Review the RCS England LDS Part 2 regulations and four components** — LDS Part 2 assesses Safe Beginner competence across four components in London: the Operative Test on a Dental Manikin, the Objective Structured Clinical Examination (OSCE), the Diagnostic and Treatment Planning (DTP) exercise, and the Medical Emergencies (ME) examination.
2. **Practise 5-minute OSCE consultations and clinical vivas against the clock** — Each OSCE station lasts 5 minutes after 1 minute of reading time. Rehearse taking a focused dental and medical history, explaining diagnoses and treatment options without jargon, obtaining Montgomery-compliant informed consent, and answering structured viva questions on dental prescribing, IR(ME)R 2017 and HTM 01-05.
3. **Rehearse both stages of Diagnostic and Treatment Planning (DTP)** — Practise the 13-minute simulated patient history consultation (after 3 minutes of reading time) and the 15-minute examiner oral (after 3 minutes of reading time). Present special investigations, radiographs and periodontal charting systematically, state tooth-by-tooth prognoses, and set out a phased treatment plan.
4. **Speak through Medical Emergencies in Dental Practice using ABCDE** — Rehearse the 15-minute Medical Emergencies oral (after 2 minutes of reading time), covering immediate ABCDE assessment, oxygen delivery, and Resuscitation Council UK and BNF Dental Practitioners' Formulary emergency drug routes and regimens for anaphylaxis, adrenal crisis, acute asthma, hypoglycaemia, cardiac chest pain, status epilepticus and choking.
5. **Prepare for ethics, safeguarding and GDC Duty of Candour stations** — Practise handling urgent two-week-wait oral cancer referrals, paediatric consultations with a parent or carer (dental trauma, caries prevention, safeguarding), and transparent GDC Duty of Candour disclosures after iatrogenic complications.

## Sample LDS Part 2 questions

- *Diagnostic & Treatment Planning — Examiner Oral:* A 54-year-old patient taking apixaban for atrial fibrillation presents with generalised periodontitis, secondary caries under an upper molar crown, and an unrestorable lower premolar root. Present your diagnoses, special investigations, and phased treatment plan.
- *Medical Emergencies in Dental Practice Viva:* Five minutes after taking amoxicillin 3 g orally for prophylaxis prior to an extraction, a 46-year-old patient develops stridor, wheeze, facial swelling, and a blood pressure of 82/48 mmHg in the dental chair. Talk through your immediate ABCDE assessment, positioning, oxygen therapy, and drug management.

## Example scenarios

- *OSCE — History & Information Gathering:* A 68-year-old man on apixaban for atrial fibrillation and alendronic acid for osteoporosis attends with a painful, mobile lower first molar. Take a focused dental and medical history and assess his extraction risk.
- *OSCE — Breaking Bad News, Ethics & Candour:* A 56-year-old smoker has a persistent 2 cm indurated ulcer on the lateral border of his tongue present for four weeks. Explain why you are referring him on the urgent two-week-wait head and neck pathway.

- *Medical Emergencies in Dental Practice Viva:* Two minutes after you administer an inferior alveolar nerve block and prescribe amoxicillin, your 34-year-old patient develops stridor, wheeze, facial swelling and hypotension (BP 78/42 mmHg). Talk the examiner through your immediate management and emergency drug doses.

## How a practice session works

1. **Choose a station** — Pick from 8 station types drawn from the real LDS Part 2 curriculum, or run a full mock that takes you through them as a circuit.
2. **Have the conversation** — Speak naturally, out loud. The AI patient or examiner responds in real time — with follow-up questions, emotions, cues and unexpected turns, just like the real stations.
3. **Get instant feedback** — The moment you finish, you get specific, examiner-style feedback and a score — what you did well, what cost you marks, and precisely what to fix before the next attempt.

## About MedMock

MedMock is a web app for practising the spoken parts of UK medical and dental exams and interviews out loud. The candidate talks; an AI patient, examiner or interview panel answers in real time by voice; and when the station ends MedMock marks the performance against that exam's assessment domains and shows the model answer.

It covers 104 spoken exams and interviews — OSCEs, vivas, structured oral exams, simulated consultations, and specialty-training and consultant interviews. It does not cover written or multiple-choice papers, and it is not a question bank.

It was founded by Mr Sam Nahas, MBBS BSc MEd FRCS (Tr & Orth), a practising consultant orthopaedic surgeon in the UK, with co-founder and CTO Arjan Jandu. It is operated by VirtualPatients Ltd (company no. 16303492).

Pricing: a one-off £5 taster of 30 credits to try it (not a subscription, one per account), and a monthly subscription from £20 to £129 depending on the exam (student exams cost least, fellowship exit exams and consultant interviews most), or £199 to £275 for the Intensive plans, which carry more credits. One credit is one minute of spoken practice, or two typed exchanges, and where the examiner or patient speaks first, that opening line is free. Examiner scorecards, mark schemes and model answers for finished sessions are included at no extra credit cost. Subscriptions can be cancelled at any time.

It runs in a web browser on a laptop or phone; spoken practice needs a microphone. There is no public demo: practice needs an account with credits, usually from the taster or a monthly plan.

MedMock is for adults aged 18 or over. Sign-up asks every new account to confirm it.

MedMock is a revision tool. The patients, examiners and cases are fictional and AI-generated; it is not clinical guidance and is not affiliated with or endorsed by any Royal College, the GMC, the GDC or any examining body.
