amelogenesis

 [ah-mel″o-jen´ĕ-sis]
formation of dental enamel.
amelogenesis imperfec´ta a hereditary disease in which there is imperfect formation of enamel, resulting in brownish coloration and friability of the teeth.

am·e·lo·gen·e·sis im·per·fec·ta

a group of hereditary ectodermal disorders in which the enamel is defective in structure or deficient in quantity. Three major groups are recognized: hypoplastic types, with defective enamel matrix deposition but normal mineralization; hypomineralization types, with normal matrix but defective mineralization; and hypomaturation type, in which the enamel crystallites remain immature. The several types may be inherited as autosomal dominant [MIM*104500, 104510, 104530], recessive [MIM*204650, 204690, 204700] or X-linked [MIM*301100, 301200, 301201].

amelogenesis imperfecta

(ĭm′pər-fĕk′tə)
n.
A hereditary condition in which the dental enamel does not develop properly, often because of insufficient calcification.

Hereditary ectodermal disorders in which dental enamel is defective in structure or deficient in quantity.

amelogenesis imperfecta

A hereditary defect of the mineralization of tooth enamel which is unusually soft and is rapidly worn away.

(amĕ-lō-jenĕ-sis im-pĕr-fektă)
