Pulpal and apical diagnosis
Combine symptom pattern, sensibility tests, percussion, palpation and radiographs. State pulpal and apical diagnoses separately.
Understand
A pulpal diagnosis describes the pulp's condition; an apical diagnosis describes the tissues around the apex. These can differ, and a radiolucency may lag behind symptoms.
Assess
Take a precise pain history, test the suspect and control teeth, palpate and percuss, and inspect the whole radiograph. A positive cold response does not prove normal perfusion or exclude disease.
Apply
State both diagnoses and the uncertainty before choosing treatment. If findings conflict, reassess, test again or refer rather than starting irreversible care on a weak diagnosis.
Key distinctions
Pulpal terms describe clinical estimates such as reversible or irreversible inflammation and necrosis; apical terms describe normal tissues, symptomatic inflammation, abscess or other findings. A tooth with a vital response may still be tender apically from occlusal trauma or periodontal disease. Record what evidence supports each label and revisit it if treatment does not fit the course.
Think through a case
A tooth is tender to percussion but responds normally to cold. The apical pain may have another source; don't label the pulp necrotic from tenderness alone.
The distinction to remember
Do not collapse pulpal and apical findings into one diagnosis. State each separately and record tests on adjacent control teeth.
Test your recall
Can a periapical radiolucency alone establish pulp status?
Show answer
No; it must be interpreted with clinical tests and history.
