ADEX OSCE Overview – Format, Topics & Passing Strategy

1. What the ADEX OSCE is designed to test

The OSCE evaluates judgement, not hand skills. Examiners want to know if you can make safe, appropriate decisions under pressure.

Every question maps to real-world clinical expectations, making this section highly teachable once you understand the patterns.

2. OSCE structure and format

The OSCE is completed on a computer and features:

• Case-based patient scenarios
• Radiographs and clinical photos
• Multiple-choice and single-best-answer questions
• No written notes or long-answer format

3. Radiology – the highest-yield OSCE section

Radiographs appear in almost every OSCE form. You must recognise:

• Caries depth and direction
• Periapical pathology
• Periodontal bone loss patterns
• Anatomical landmarks
• Common errors (foreshortening, cone-cut, overlap)

Most incorrect answers come from misreading bone levels or pulp morphology.

4. Medical emergencies – predictable question patterns

ADEX repeatedly tests: angina, hypoglycemia, syncope, anaphylaxis, and asthma.

• Recognise symptoms quickly
• Know first-line medications
• Stabilise before definitive care
• Use oxygen appropriately

5. Treatment planning – sequencing matters

Many OSCE questions ask: “What is the next best step?” The sequence often follows:

• Stabilise chief complaint
• Control infection or acute disease
• Address periodontal foundation
• Restore caries or structural issues
• Plan definitive restorative care

Overlooking perio or ignoring patient factors is a common reason for wrong answers.

6. Ethics & legal scenarios

These questions look simple but can trap candidates who choose the “clinically correct” option instead of the “professionally appropriate” one.

• Obtain consent before any irreversible procedure
• Disclose mistakes honestly
• Document everything
• Respect scope of practice

7. How the OSCE is scored

Each response is either correct or incorrect. There is no partial credit and no penalty for guessing.

Performance is compared to a calibrated passing threshold. Strong performance in high-weight sections (radiology, emergencies) can offset weaker areas.

8. How to prepare for the OSCE the smart way

The highest-yield preparation method includes:

• Short, repeated review sessions (10–15 minutes each)
• Practising cases under timed conditions
• Memorising emergency drug doses and first-line actions
• Training your eyes for radiograph interpretation
• Learning sequencing logic for treatment planning

9. How this connects with the ADEX clinical (manikin) skills

Candidates who understand the OSCE well often perform better in the clinical portion too — because both sections reward safe, thoughtful decision-making.

If you haven’t read the ADEX scoring and manikin articles yet, go back and review them to connect the full exam structure.
