Radicular (type 1) dentin dysplasia.
Radicular dentin dysplasia is a peculiar anomaly in which abnormal dentin resembling the plici-dentin found in certain fish and reptiles obliterates the pulp chamber. The almost complete absence of roots leads to the early loss of teeth and predisposes to paradontal infection and the formation of cysts.
