Purpose The American Academy of Pediatric Dentistry (AAPD) recognizes that pediatric dentists are uniquely qualified to manage the oral health care needs of children with heritable dental developmental anomalies. These children have multiple, complex problems as their dental conditions affect both form and function and can have significant psychological impact. These conditions may present earl...

Ectodermal dysplasias are a large group of heterogeneous heritable conditions characterized by congenital defects of ectodermal structures and their appendages: hair (hypotrichosis, partial or total alopecia), nails (dystrophic, hypertrophic, abnormally keratinized), teeth (enamel defect or absent) and sweat glands (hypoplastic or aplastic). The ectodermal dysplasias, as a rule, are not pure “o...

Ectodermal dysplasias (EDs)are a heterogenous group of hereditary disorders characterized by certain shared structural and functional abnormalities in tissues derived from the ectoderm [1]. They are characterized by deficient function of at least 2 ectodermal derivatives such as skin, hair, teeth and sweat glands. Although more than 170 different subtypes of ectodermal dysplasia have been ident...

Hypohidrotic ectodermal dysplasia (HED) is a rare genetic disorder caused by mutation in either the ectodysplasin (EDA), A receptor (EDAR), EDAR associated via death domain (EDARADD), or Wnt family member 10A (WNT10A) genes that result impaired development of ectodermal-derived structures. The literature defines two types dysplasia, which are hypohidrotic and hidrotic. X‐linked (XLHED), also kn...

Introduction Ectodermal dysplasia (ED) is a clinically heterogeneous condition characterized by the abnormal development of two or more ectoderm-derived structures. Mutations in ED1 gene, (Xq12-13.1), are the most frequent cause. X-linked Hypohidrotic Ectodermal Dysplasia (XL-HED) is characterized by association of sparse hair, abnormal or missing teeth and variable inability to sweat that may ...

Ectodermal dysplasia is a hereditary disorder that occurs as a consequence of disturbances in the ectoderm of the developing embryo. The triad of nail dystrophy, alopecia or hypotrichosis and palmoplantar hyperkeratosis is usually accompanied by a lack of sweat glands and a partial or complete absence of primary and/or permanent dentition. Two case reports illustrating the prosthetic rehabilita...
