Amelogenesis imperfecta and unusual gingival hyperplasia.

BACKGROUND
Amelogenesis imperfecta (AI) is a group of hereditary conditions that primarily involves the defective formation and/or calcification of enamel. The association of AI with gingival enlargement-like lesions has also been reported.


METHODS
This paper reports a case of a hypoplastic AI associated with unusual generalized gingival hyperplasia.


RESULTS
Histological aspect of the gingival growth was characterized by a dense connective tissue with a mild mononuclear inflammatory infiltrate, calcified bodies, and islands of odontogenic epithelium.


CONCLUSION
The present case represents a very interesting demonstration of the fact that, although rare, AI may be associated with generalized gingival enlargement.
