How to Present a Dental Case in Viva (Without Losing Marks)

A case presentation is not a summary of what you found. It's a demonstration that you can reason from complaint to diagnosis to plan without skipping a step. Examiners can tell within ninety seconds whether you have a system, and the mark is largely decided by then.

The structure — use it every time

1. Identification and chief complaint

Name, age, sex, occupation. Then the complaint in the patient's own words, with duration. "A 34-year-old male presents with pain in the lower right back tooth region for the past five days."

2. History of the present illness

Onset, duration, character, aggravating and relieving factors, radiation, associated symptoms, previous treatment. For dental pain, be specific: is it spontaneous or provoked, does it linger, does it wake the patient at night, is it localised or diffuse? These distinctions carry the diagnosis.

3. Medical, dental, personal and family history

Medical history relevant to dental management — diabetes, hypertension, cardiac conditions, bleeding disorders, allergies, current medications. Personal history should include tobacco, alcohol and paan use with quantity and duration. Do not skip this; examiners frequently build their questions from it.

4. Examination

General: build, gait, obvious findings. Extraoral: facial symmetry, swelling, lymph nodes, TMJ. Intraoral: soft tissues first, then hard tissues, then a tooth-by-tooth chart. State positive findings and relevant negatives — "no lymphadenopathy" is information.

5. Provisional diagnosis

State it clearly and justify it from your findings. Then give a differential — two or three alternatives with a one-line reason each for why they're less likely. The differential is where good candidates separate from average ones.

6. Investigations

What you'd order and why. Naming an IOPA is baseline; saying "an IOPA to assess the periapical status and the extent of the lesion relative to the pulp" shows you know what you're looking for.

7. Final diagnosis

8. Treatment plan, in phases

Emergency/pain relief → disease control → definitive treatment → maintenance. Presenting a plan in phases demonstrates you understand sequencing, which is the actual clinical skill being assessed.

9. Prognosis

With reasoning. What would improve it, what would worsen it.

The four mistakes that lose marks

• Jumping to the diagnosis. Leading with "this is irreversible pulpitis" and working backwards. Present the reasoning in order; the examiner is marking the path.
• Omitting relevant negatives. They demonstrate you looked.
• A treatment plan with no sequence. Listing procedures is not a plan.
• Guessing confidently. A clean "I'm not sure" costs one mark. A confident wrong answer invites three more questions on the same gap.

Practical preparation

• Rehearse aloud with a batchmate. Knowing it and saying it fluently are different skills.
• Time yourself — most presentations should run five to seven minutes.
• Prepare for the obvious follow-ups: classification of the condition, aetiology, why you chose this treatment over the alternative.
• Know the classification of whatever you diagnose. It's the most predictable follow-up question in dental viva.

When you're asked something you don't know

Say so, and offer the reasoning you do have: "I'm not certain of the exact classification, but based on the clinical presentation I'd expect it to fall under…" That shows thinking, which is what's being marked. Silence and bluffing both score zero.
