Amelogenesis Imperfecta, Type Iiia; Ai3a

Description

Hypocalcified amelogenesis imperfecta is characterized by enamel of normal thickness on newly erupted and unerupted and unresolved teeth. The enamel is soft and may be lost soon after eruption leaving the crown composed only of dentin. The enamel has a cheesy consistency and can be scraped from the dentin. An anterior open bite has been recorded in over 60% of the cases observed. The hypocalcification type is the most frequent type of enamel dysplasia, occurring in about 1 in 20,000 individuals (Witkop and Sauk, 1976). Large masses of supragingival calculus become deposited on the teeth, and this is frequently associated with severe gingivitis or periodontitis (Winter and Brook, 1975).
