Prosthetic rehabilitation of a child with X-linked hypohidrotic ectodermal dysplasia: a case report and 12-month follow-up.

The hereditary condition known as ectodermal dysplasia (ED) is characterized by the absence of or a defect in 2 or more ectodermally derived structures such as skin, nails, hair, sweat glands, or teeth. Patients with this disorder usually present with reduced salivary gland function and absence of some or all teeth, which compromises orofacial function and development. In addition, children with ED usually experience difficulty in social interactions because of their appearance.
