Vitamin D-dependent rickets (VDDR) describes a group of genetic disorders that are characterized by early-onset rickets due to the inability to maintain adequate concentrations of active forms of vitamin D or a failure to respond fully to activated vitamin D. The prevalence rate is usually reported to be around 1:20,000. The oral manifestation includes dentin defects, unusually large pulp chambers, and enlarged pulp horns, hypoplastic enamel which is mostly seen in primary teeth than in permanent teeth. The present case report of VDDR in an 8.5-year-old female child highlights the clinical and radiographic features of the oral cavity along with the prosthetic rehabilitation to restore her stomatognathic functions.
