A panoramic radiograph shows a tooth with a 'tooth within a tooth' appearance on the X-ray. What is the diagnosis?
Show answer and explanation
Correct answer: A. Dens Invaginatus
✓ A) Dens Invaginatus is correct.
Dens invaginatus ('dens in dente' / tooth within a tooth) occurs when the enamel organ invaginates into the developing tooth crown before calcification. Radiographically, it appears as an enamel-density structure within the tooth — a 'tooth within a tooth'. It most commonly affects the maxillary lateral incisors. It predisposes to pulp necrosis as the invagination creates a communication pathway for bacteria.
