of age. Multiple denture replacements are often needed as the child grows, and dental implants may be an option in adolescence, once the jaw is fully grown. Nowadays the option of extracting the teeth and substituting them with dental implants is quite common. In other cases, teeth can be crowned. Orthodontic treatment also may be necessary. Because dental treatment is complex, a multi-disciplinary approach is best. Other features People with ED often have certain cranial-facial features which can be distinctive: frontal bossing is common, longer or more pronounced chins are frequent, broader noses are also very common. Sunken cheeks, wrinkled hyper pigmented periorbital skin , thick everted protuberant lips are also seen in ED cases .In some types of ED, abnormal development of parts of the eye can result in dryness of the eye, cataracts, and vision defects. Professional eye care can help minimize the effects of ED on vision. Similarly, abnormalities in the development of the ear may cause hearing problems. Respiratory infections can be more common because the normal protective secretions of the mouth and nose are not present. Precautions must be taken to limit infections.. Genetics ED can be classified by inheritance (autosomal dominant, autosomal recessive and X-linked) or by which structures are involved (hair, teeth, nails and/or sweat glands). There are several different types with distinct genetic causes: Hay–Wells syndrome (Rapp–Hodgkin syndrome) and EEC syndrome are all associated with TP63. Hypohidrotic ectodermal dysplasia can be associated with EDA, EDAR and EDARADD. Margarita Island ectodermal dysplasia is associated with PVRL1. Ectodermal dysplasia with skin fragility is associated with PKP1. Clouston's hidrotic ectodermal dysplasia is associated with GJB6. Naegeli syndrome/Dermatopathia pigmentosa reticulariss is associated with KRT14. Pachyonychia congenita is caused by multiple keratins. Focal dermal hypoplasia is associated with PORCN. Ellis–van Creveld syndrome is associated with EVC. Palmoplantar ectodermal dysplasia refers to several different conditions selectively affecting the hands and feet. Diagnosis In terms of the clinical evaluation, clinical features are the classification method Treatment Management for this condition is symptom specific Society and culture Notable cases Michael Berryman, American actor with hypohidrotic ectodermal dysplasia Levi Hawken, New Zealand skateboarder and artist who became well known in 2011 in New Zealand for the "Nek minnit" viral video on YouTube See also List of cutaneous conditions List of cutaneous conditions caused by mutations in keratins References External links Genodermatoses Syndromes affecting teeth Ectoderm
