Tooth and nail syndrome, an autosomal dominant condition, is characterized by hypodontia and nail dysplasia. Mandibular incisors, second molars and maxillary canines are the most frequently missing teeth. Tooth shape may vary and conical and narrow crowns are common. Nail dysplasia affects fingernails and toenails and is often more severe in childhood. Nails may be spoon-shaped, ridged, slow growing and easily broken. The clinical and radiographic features of a father and son presenting with this rare condition are described.
