Ectodermal dysplasias are a large, multifarious group of inherited disorders, characterized by a flaw in the tissues derived from the embryonic ectoderm. The incidence of ectodermal dysplasia is rare. Various alterations in the genes coding for proteins like EDA, EDAR, EDARADD are the causes for the manifestations of ectodermal dysplasia. Oligodontia or hypodontia of the deciduous and/ or permanent dentition is the most common intra-oral finding. Ectodermal dysplasia is not only physically devastating to the patients but also emotionally demoralizing. It is essential that they be treated at an early age to improve their quality of life. The following case report aims at describing the condition in a patient with complete anodontia and discusses the genetic component of the disorder. Oral rehabilitation was achieved by using removable prosthesis.
Key words: Ectodermal Dysplasia; EDA; EDAR; EDARADD; Anodontia.
