Hereditary gingival fibromatosis (HGF) is a rare condition characterised by severe gingival hyperplasia, which could result in serious aesthetic and emotional problems and functional impairment. Here the present authors report a case of a 28-year-old female patient with generalised severe gingival enlargement covering almost all of the teeth and diagnosed as HGF. Her family history was of significance, since her father and 3-year-old daughter suffered from the same symptoms. Many studies have agreed that surgical removal should be used in the treatment of HGF, and gingivectomy is the most common method. This study tried both external and internal bevel incisions. The results suggest that the former is better for shaping gingival contour, if the attached gingiva is adequate. Correct physiological contour of the marginal gingiva, good oral hygiene and periodic recall can decrease recurrence risk. Post-surgical follow-up after 26 months demonstrated no recurrence and the patient was satisfied with her appearance.
