Question 92 · LDEK · Children with systemic diseases and disabilities

In an X-linked vitamin D-resistant rickets one can find:

1) large pulp chambers with horns extending up to the dentino-enamel junction;
2) elongated pulp chambers with root furcations moved towards the apices;
3) delayed apical root closures;
4) small pulp chambers;
5) pulp stones.
The correct answer is:
  1. A. 1,5.
  2. B. 1,3.
  3. C. 2,3.
  4. D. 4,5.
  5. E. 2,5.
Hint

Consider how poorly mineralized dentine in hypophosphatemic rickets affects the size of the pulp space and the timing of root completion.
