Enamel Hypoplasia, Dental

A form of AMELOGENESIS IMPERFECTA characterized by incomplete formation of the dental enamel and transmitted as an X-linked or autosomal dominant trait. It is also associated with vitamin A, C, or D deficiency, infectious disease, prematurity, birth injury, Rh incompatibility, trauma, or local infection. Small grooves, pits, and fissures are seen in mild cases, deep horizontal rows of pits in severe cases, or absence of enamel in extreme cases. (Dorland, 27th ed)
