Dentinogenesis Imperfecta Associated with Hypophosphatemic Rickets- A Report of the Rarest Case

Abstract

Rickets is a childhood bone disorder. It is caused due to deficiency of Vitamin D, calcium, and phosphate. Bones become soft and weak and are prone to fracture due to inadequate intake of these nutrients. Rickets result from abnormalities of the growth plate cartilage predominantly affecting longer bones and leading to poor bone growth, defective mineralization, and bony deformities such as bow legs and knock-knees. This case report presents a rare case of a 21-year-old female patient with discoloration and abnormalities of teeth since childhood with hypophosphatemic rickets in early childhood who suffered from subsequent loss of tooth structure and bone deformities. Orthopantomogram revealed bulbous crowns of teeth with cervical constriction, obliterated pulp chambers, and slender roots. X-ray chest revealed decreased costochondral angle suggestive of pigeon chest. Serum calcium and Vitamin D were, but serum phosphorus levels were decreased. The patient was examined by a Physician & Orthopedic Surgeon. On the basis of clinical-radiographic features and serum biochemistry findings, this case was diagnosed as Dentinogenesis Imperfecta associated with Hypophosphatemic Rickets.
