Which radiographic finding is typical for Dentinogenesis Imperfecta?

Open bite
Bulbous crowns
Impacted molars
Deep bite

The correct answer is: Bulbous crowns

Dentinogenesis Imperfecta is a genetic disorder that affects the formation of dentin, leading to distinctive dental features. One of the hallmark radiographic findings associated with this condition is the appearance of bulbous crowns. This characteristic is due to the abnormal development and mineralization of the dentin, which results in crowns that appear wider at the incisal edges and more tapered towards the cervix. The altered dentin structure not only affects the aesthetics but also makes the teeth more prone to fractures and other complications. The other options do not represent typical findings associated with Dentinogenesis Imperfecta. Open bites, impacted molars, and deep bites may occur in various dental conditions but are not specifically indicative of the changes brought about by this disorder. Bulbous crowns serve as a defining feature that aids in the diagnosis of Dentinogenesis Imperfecta upon radiographic examination.
