[Gingival "thickening" in malformation syndromes. I].

The etiology of generalized gingival enlargement is very heterogeneous. Pregnancy, drugs, systemic diseases, poor oral hygiene, and nutritional impairment can lead to gingival enlargement. This defect can also be presented in several malformation syndromes. Gingival fibromatosis, that may exist as an isolated abnormality or as part of a syndrome, is another condition with gingival enlargement. In this paper, the malformation syndromes with gingival hypertrophy and those with gingival fibromatosis are listed in tables.
