Description

We presented two cases of gingival fibromatosis, one with hereditary gingival fibromatosis (HGF) and another with idiopathic gingival fibromatosis (IGF). The Case 1 patient was a boy (2 years 10 months old) with gingival hypertrophy. His father and grandmother also had similar conditions in their childhood. An intraoral examination showed that nearly all teeth were covered with enlarged gingiva, while histopathological findings demonstrated thickening of the epithelium. Under the epithelium, cell components were sparse and collagen fibrils were dense, with slight cellular infiltration. Our diagnosis was hereditary gingival fibromatosis. The Case 2 patient was a girl (10 years 0 months old) with gingival enlargement. Her medical history was irrelevant and family history was negative. Gingival hyperplasia was observed over the maxilla and mandible, which covered half to two-thirds of the crown of each tooth. The histological characteristics were nearly the same as in Case 1. Our diagnosis was idiopathic gingival fibromatosis. We performed a gingivectomy several times in both cases as well as periodic oral hygiene consultations because of the recurrence of gingival hyperplasia. With improvement of oral hygiene technique, good results were seen in both cases. Our experience reconfirmed the importance of plaque control for treating gingival fibromatosis.
