Which condition BEST mimics irreversible pulpitis (referred pain/mimic)?
Show answer and explanation
Correct answer: B. Sinusitis
B) Sinusitis — CORRECT.
Maxillary sinusitis is the classic mimic of pulpitis in the posterior maxillary teeth. Inflamed sinus mucosa compresses the roots of maxillary posterior teeth (especially premolars and first molars whose roots are in close proximity to the sinus floor), causing bilateral, diffuse, non-localized pain that patients describe similarly to toothache. Vital teeth + percussion sensitivity + no radiographic pathology + bilateral involvement = consider sinusitis.
A) Angina: Cardiac pain can radiate to the mandible (left side), mimicking toothache — important to know, but sinusitis more specifically mimics pulpitis with its mechanism.
C) Otitis media: Can cause referred ear/jaw pain but doesn't mimic pulpitis as specifically as sinusitis.
D) Trigeminal neuralgia: Causes sharp, electric, lancinating pain — different character from pulpitis.
