What dental structure is typically compromised in Dentinogenesis Imperfecta?

Dentinogenesis Imperfecta is an inherited condition primarily affecting the development of dentin, which is the hard tissue beneath the enamel in teeth. This disorder leads to the production of abnormal dentin, resulting in teeth that are discolored (often having a blue-gray or yellow-brown appearance) and more prone to fractures. Since dentin serves as a crucial structural component of the tooth, its compromise directly affects the integrity and strength of the teeth, making them vulnerable to decay and other dental issues.

The enamel, while important for the overall structure of the tooth, is not compromised in Dentinogenesis Imperfecta; rather, it may appear normal but is less effective due to the underlying dentin’s weakness. The primary alveolar bone and the pulp are also not directly affected by this condition. The primary focus of Dentinogenesis Imperfecta is indeed the dentin itself, confirming why this structure is considered typically compromised in the disorder.
