Which radiographic feature is indicative of amelogenesis imperfecta?

• A. Bulbous crowns
• B. Yellow or brown discoloration
• C. Thin roots
• D. Cervical constriction

Answer: (B)

The radiographic feature indicative of amelogenesis imperfecta is the presence of yellow or brown discoloration of the teeth. Amelogenesis imperfecta is a genetic condition that affects the enamel formation, resulting in enamel that is poorly mineralized or completely absent. This defect leads to altered coloration, often presenting as yellow or brown shades rather than the normal white or pearly appearance of healthy enamel. The discoloration is a direct result of the enamel's insufficient mineral composition, making it less reflective and more prone to staining or yellowing. Patients with this condition may also experience sensitivity and increased susceptibility to caries because the compromised enamel provides less protection to the underlying tooth structure. While other features like bulbous crowns or cervical constriction might be observed in certain cases of amelogenesis imperfecta, the characteristic discoloration is among the most consistent and defining features noted in radiographic assessments.
