Orthopantomogram showed poor development of the upper and lower dento-alveoli with multiple unerupted permanent teeth. The roots of the retained primary teeth were partially resorbed, and the pulp chambers of upper and lower right primary teeth were obliterated. The permanent teeth had bulbous crown and short roots. The lower right first molar and all second and third permanent molars were impacted. Others unerupted permanent teeth positioned cervically to their retained primary predecessors.
