Show answer and explanation
Correct answer: C. Excisional biopsy
✓ C) Excisional biopsy is the EXCEPTION — NOT done for aphthous ulcers.
Minor aphthous ulcers are clinical diagnoses — biopsy is NOT indicated unless the lesion is: >2 cm, persisting >3 weeks, unusual appearance, or suspected malignancy. Treatment includes: chlorhexidine mouthwash (reduces secondary infection/duration), topical corticosteroids (first-line), topical anesthetics, laser therapy (promotes healing, reduces pain), and amlexanox paste. Excisional biopsy would be inappropriate and traumatic for a benign aphthous ulcer.
