Radiograph shows:
Clinical  Features: The teeth affected by odontodysplasia exhibit either a delay or a total failure in eruption. Their shape is markedly altered,  being generally very irregular in appearance, often with evidence of defective mineralization.
Radiographic  Features: The radiographs are uniquely characteristic, showing a marked reduction in radiodensity so that the teeth assume a ‘ghost’ appearance. Both the enamel and dentin appear very thin and the pulp chamber is exceedingly large. The enamel layer often is not evident.
Key Concept
The unusually large pulp, thin enamel and dentin are evident.
