What is a common dental characteristic of Vitamin D resistant rickets?

The characteristic associated with Vitamin D resistant rickets is hypocalcified enamel, which often manifests as poor mineralization of the enamel. This condition results from a deficiency in calcium and phosphate, causing the enamel to be less dense and more prone to decay.

Individuals with Vitamin D resistant rickets often have disturbances during their teeth development that lead to defects in enamel formation, which is characterized by inadequate mineralization. This can result in the enamel appearing pitted, hypoplastic, or hypocalcified. Therefore, the presence of hypocalcified enamel aligns with the pathology of Vitamin D resistant rickets.

Understanding that Vitamin D plays a critical role in calcium homeostasis and bone health clarifies why inadequate Vitamin D affects dental structure. The options listed, such as enlarged pulp chambers, spare enamel, and increased dentin thickness, are not typically relevant to the effects of this specific condition. In contrast, hypocalcified enamel is a direct consequence of the mineralization issues that occur in patients with this form of rickets, linking the dental manifestation directly to the systemic metabolic disturbance.
