  2. Prescribe antibiotics empirically
  3. Provide a hard occlusal guard
  4. Reassure and dismiss the patient
Show answer and explanation

Correct answer: A. Refer for/perform a biopsy to establish a definitive diagnosis

A persistent, undiagnosed mucosal lesion requires biopsy (often perilesional for immunofluorescence in vesiculobullous disease) to establish a diagnosis before treatment.Other options: Empiric antibiotics, an occlusal guard, or dismissal do not diagnose the lesion.Key exam takeaway: Persistent undiagnosed mucosal lesion = biopsy for definitive diagnosis.
