RESUMO
Hereditary Gingival Fibromatosis [HGF] also referred to as idiopathic gingival hyperplasia is a rare type of slow growing gingival enlargement with great clinical and genetic heterogeneity inherited usually as Mendelian autosomal dominant fashion. Occurring as an isolated trait [HGF] and/or as a component of a syndrome, the affected gingival is characterized by firms, asymptomatic, non-hemorrhagic enlarged [hyperplastic] tissue with characteristic pale pink colour, covering most of the anatomic crown, involving usually all the quadrants. There is no definitive treatment present but post pubertal surgical intervention and good oral hygiene maintenance can improve the compromised esthetics and function of the patient. This paper presents a case report of a 15 year old male suffering from hereditary gingival fibromatosis with a positive family history. Periodontal management including gingivectomy [external bevel] was being undertaken after biopsy
