Total anodontia in patient with hypohidrotic ectodermal dysplasia. Report of rare case of Christ-Siemens Touraine syndrome.

Ectodermal dysplasias are a complex group of genetically determined disorders clinically characterized by congenital alterations of the structures derived from the ectoderm. Even though ectodermal dysplasia with partial anodontia is common, this condition with total anodontia is not. We describe features of hypohidrotic ectodermal dysplasia with complete anodontia in a 6-year-old boy. In order to improve esthetics, speech and mastication, the child was provided with upper and lower complete dentures.
