A patient has dentinogenesis imperfecta. What could be seen clinically/radiographically?

  1. Chevron-shaped pulp
  2. Pitted enamel
  3. Blue, translucent enamel/teeth
  4. White spots
Show answer and explanation

Correct answer: C. Blue, translucent enamel/teeth

Dentinogenesis imperfecta classically produces teeth with an opalescent, blue-grey to brown translucent appearance, bulbous crowns, and (radiographically) obliterated pulp chambers/canals with thin, constricted roots. Pitted enamel is more characteristic of certain amelogenesis imperfecta subtypes, and white spot lesions are typically associated with early caries or fluorosis, not DI.
