Dentin Dysplasia is primarily characterized by abnormal dentin formation, which results in pulpal obliteration. This occurs because the dentin structure is altered, leading to a progressive narrowing of the pulp chamber and canals over time. As dentin is formed improperly, the pulp space becomes reduced, often resulting in a lack of sufficient pulp tissue. This condition can impact the overall vitality of teeth, making them more susceptible to decay and infection. The focus on pulpal obliteration highlights the key relationship between dentin development and pulp health, which is a significant aspect of Dentin Dysplasia.

The other options, while they may describe features seen in different dental conditions, do not accurately reflect the primary characteristic of Dentin Dysplasia. For instance, visible enamel crumbling and soft dentin generally relate to other enamel disorders or conditions affecting the enamel's integrity but not the specific dentin abnormalities seen in this dysplasia. Enlarged pulp chambers could suggest different dental conditions such as pulp hyperplasia or other forms of dysplasia but do not describe the typical presentation associated with Dentin Dysplasia.
