A patient has dentinogenesis imperfecta. What is the most characteristic clinical finding?

Correct answer: C. Blue/amber opalescent (translucent) teeth

• A. Pitted enamel is characteristic of amelogenesis imperfecta (hypoplastic type), not dentinogenesis imperfecta.
• B. White spot lesions are early enamel demineralization (caries), unrelated to DI.
• C. Dentinogenesis imperfecta (DI) causes blue-gray to amber/brown teeth with an opalescent (translucent) quality. Enamel fractures easily due to lack of normal dentin support. Pulp chambers obliterate progressively.
• D. Chevron pulps are not characteristic of dentinogenesis imperfecta.
