Dentinogenesis Imperfecta is a hereditary condition affecting dentin formation, leading to discolored and weakened teeth. Ectodermal Dysplasia is a genetic disorder affecting multiple ectodermal structures including hair, skin, and teeth. Amelogenesis Imperfecta is a congenital disorder that affects enamel formation on teeth. Among the options provided, regional odontodysplasia is the most fitting description for the condition indicated by 'ghost teeth'.
