ADEX Treatment Planning OSCE – Next Best Step Guide

The simple, predictable sequencing rules that help you answer almost every ADEX treatment planning OSCE case correctly.

Quick Answers

What does the Treatment Planning OSCE test?

Whether you choose the safest next step — not the final full plan.

What is the #1 rule?

Stabilize urgent problems before definitive treatment.

What comes first: perio or caries?

Perio control usually comes before restorative work.

When should you refer?

When the case exceeds general practice ability (complex perio, complex endo, medical risk).

How do you avoid losing marks?

Always choose the safest, least invasive, most logical step for the patient’s current condition.

What is the most tested question type?

“What is the next best step?” — based on symptoms, radiographs, and clinical findings.

1. The OSCE expects logic, not a full treatment plan

ADEX does NOT ask for multi-visit detailed plans. It asks whether you understand clinical priority and sequencing.

Every treatment planning question can be solved using one rule:

Golden Rule

Urgency → Disease control → Definitive care → Maintenance.

The exam checks if you stabilise the patient before choosing elective or complex treatment.

2. The ADEX “Next Best Step” algorithm

  • Is there pain, swelling, or infection? → Treat that first.
  • Is there uncontrolled perio? → Control inflammation.
  • Is caries active or severe? → Remove disease before prosthetics.
  • Is the tooth non-restorable? → Extract before planning.
  • Is the patient medically unstable? → Defer elective care.
  • Is the case beyond general dentist scope? → Refer.

These patterns appear in every ADEX OSCE form in slightly different cases and are often paired with radiographic findings. For a deeper look at how images drive these decisions, see the ADEX Radiographic Interpretation guide.

3. Common scenario 1 – Tooth pain & radiolucency

Radiograph: periapical radiolucency, symptoms of irreversible pulpitis or necrosis.

Next best step:
  • Initiate endodontic treatment or refer for root canal.

Wrong answers usually involve: “crown”, “post”, “bridge”, or elective prosthodontics.

4. Common scenario 2 – Severe gingival inflammation

Patient presents with bleeding, deep pockets, inflammation.

Next best step:
  • Perform periodontal therapy (scaling + OHI).

NOT crown, NOT veneer, NOT implant. Perio always comes before definitive restorative.

5. Common scenario 3 – Caries under existing restoration

Exam shows caries progression under an old filling.

Next best step:
  • Replace the restoration or remove caries and restore.

Not RCT unless pulp is involved. Not full crown unless tooth structure is severely compromised.

6. Common scenario 4 – Tooth fractured to gingival margin

Unrestorable crown length or fracture far subgingival.

Next best step:
  • Extract the tooth → then consider replacement options.

ADEX penalizes attempts to restore clearly non-restorable teeth.

7. Common scenario 5 – Medically complex patient

Uncontrolled diabetes, high BP, angina history, recent MI.

Next best step:
  • Defer elective treatment.
  • Consult physician if needed.

Elective restorative or surgery is NEVER the answer here.

8. Referral decisions

Referral is correct when:

  • Root morphology too complex for general dentist
  • Severe periodontitis
  • Impacted teeth with surgical difficulty
  • Medically unstable patients

The safest choice is usually the correct choice.

9. How to score high on Treatment Planning OSCE

  • Identify the most urgent problem.
  • Choose the simplest and safest next step.
  • Do not skip stages (e.g., perio → prostho).
  • Do not jump into definitive care too early.
  • Always consider patient’s medical status.

Many of these decision patterns also appear in viva-style questions. For short sample answers you can rehearse, review the ADEX Common Viva Questions guide.
