Abstract

|
|
|
Vitamin D-resistant rickets(VDRR) is hereditary disease manifesting marked hypophosphatemia caused by renal tubular loss of phosphate into urine and an associated decrease in the calcium and phosphorous ion product. VDRR is identified by clinical symptoms, such as in the limbs, gait disturbance, dwarfism, familial occurrence, bowlegs, and knock-knees, as well as by laboratory findings. Dental findings are enlarged chambers and extension of the pulp horns into the cusp tips in both the primary and the permanent dentition in contrast to the vitamin D-deficient rickets. The major oral manifestations are multiple spontaneous abscesses in a caries-free dentition. We reported the clinical features and treatment of a 6-year-old boy with vitamin D-resistant rickets referred to the department of pediatric dentistry in Kyung Hee University for multiple spontaneous periapical abscesses and gingival fistula without severe dental caries.
