Oral Rehabilitation of a Child with Hypohidrotic Ectodermal Dysplasia

Hypohidrotic ectodermal dysplasia (HED) is a genetic condition characterized by abnormal development of two or more structures of the ectoderm, such as skin, hair, nails, teeth, or sweat glands. The most common dental anomalies are oligodontia and anodontia but taurodontism has also been described. These patients present a decrease of alveolar bone volume and alveolar ridge tapering due to congenitally missing teeth. The purpose of this report is to describe the case of a six-year-old girl diagnosed with HED who presented with conical teeth, taurodontic molars, and multiple agenesis that decreased the patient's self-esteem and social interactions. The proposed treatment was to accomplish an oral rehabilitation that was functional, provided the patient with the ability for correct mastication, good esthetics, and comfort, using restorations and devices that did not interfere with the child's orofacial growth and development.
