Which type of dentin dysplasia is associated with thistle tube shaped pulps and pulp stones?

The option referring to Type II: Coronal Dentin Dysplasia is associated with thistle tube-shaped pulps and pulp stones due to its specific clinical and radiographic features. This condition affects the coronal dentin, resulting in an abnormal shape of the dental pulp chamber. The thistle tube shape is a characteristic appearance seen in the pulp chambers of the affected teeth, which stands in contrast to other forms of dentin dysplasia.

Pulp stones, which are calcifications within the pulp tissue, are also commonly found in conjunction with this type of dysplasia. This combination is crucial for accurately identifying Type II: Coronal Dentin Dysplasia and differentiating it from other forms, like Type I, where the focus is primarily on root or radicular aspects, and Type III, which presents mixed characteristics. This helps in understanding the unique pathological changes and clinical manifestations associated with the condition.
