[Tooth disorders in ectodermal dysplasias]

Recently, the molecular bases of the most frequent ectodermal dysplasias have been identified; they involve genes responsible for the epithelial morphogenesis, and the regulation of cell survival and proliferation. Teeth alterations with characteristic features are often observed in X-linked anhidrotic ectodermic dysplasia and in autosomic recessive anhidrotic ectoderma, rarely in hidrotic ectodermal dysplasia.
