What characteristic X-ray finding is associated with Dentinogenesis Imperfecta?

• A. Radiolucent lesions
• B. Enlarged pulp chambers
• C. Obliterated pulp chambers and constricted crowns
• D. Fractured roots

Answer: (C)

Dentinogenesis Imperfecta is a genetic disorder that affects the structure of the teeth. The hallmark finding associated with this condition is the obliteration of pulp chambers and the appearance of constricted crowns. This occurs due to the abnormal development of dentin, which results in the teeth showing a blue-gray or amber hue, along with a tendency for the crowns to be smaller and the pulp chambers to be underdeveloped or completely obliterated. These characteristics reflect the underlying pathology of the condition, where the dentin fails to form properly, leading to a fragile tooth structure and increased risk of dental issues. The constriction of crowns and obliteration of pulp chambers is significant in diagnosing Dentinogenesis Imperfecta, as they are not commonly observed in other dental conditions. In contrast, features such as radiolucent lesions, enlarged pulp chambers, and fractured roots are not typical findings associated with this disorder. Radiolucent lesions usually indicate different pathological processes, while enlarged pulp chambers can suggest other dental issues, and fractured roots are not specifically linked to the structural abnormalities seen in Dentinogenesis Imperfecta.
