OBSERVE / REASON / EXPLAIN

Pulpal and periapical diagnostic reasoning

Integrate history and examination rather than diagnose from one test.

Original teaching scenario / OSCE

Your practical station

An examiner provides a symptom history and mixed test findings. Explain which findings you would verify before proposing a pulpal and apical diagnosis.

Recognise and interpret

Pulpal and apical assessments use complementary information; individual tests have limitations.

1

History

Characterise symptoms, triggers, duration and previous treatment.

2

Compare

Interpret relevant clinical tests against appropriate comparison teeth.

3

Integrate

Correlate examination and justified imaging before stating a provisional assessment.

At the viva table

Try answering aloud, then open the suggested answer. Examiner questions vary.

01 / Does a cold response directly measure pulpal blood flow?

No. It assesses a sensory response.

02 / Can one negative sensory test always prove necrosis?

No. Technique and clinical context matter.

03 / Does radiographic appearance replace symptom history?

No. Integrate the information.

04 / Why use comparison teeth?

They help interpret the individual response.
