    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. 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 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. 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.

Questions candidates ask

What components make up the RCS England LDS Part 2 exam?

How is LDS Part 2 different from MFDS Part 2?

LDS Part 2 is a qualifying examination for full GDC registration and includes five-minute OSCE stations, a two-stage Diagnostic and Treatment Planning exercise (13-minute patient history and 15-minute examiner oral), a 15-minute Medical Emergencies exam and a phantom-head test, whereas MFDS Part 2 is a postgraduate membership OSCE.

Does MedMock simulate the LDS Part 2 phantom-head test?

No. The three-hour Dental Manikin operative test requires hands-on phantom-head practice. MedMock simulates the spoken OSCE, Diagnostic and Treatment Planning, and Medical Emergencies viva stations.
