Hereditary gingival fibromatosis (HGF) is rare in clinical practice, and the long-term results of the combined orthodontic-periodontal treatment of HGF are rarely reported.
This study reports for the first time the results of seven years of follow-up in a seven-year-old girl with HGF. The diagnosis was confirmed by clinical signs, family history and histopathological examination. First, periodontal scaling and oral hygiene reinforcement were performed regularly in the mixed dentition stage. Next, gingivoplasty was performed on the permanent dentition. Two months after the surgery, treatment with fixed orthodontic appliances was conducted. The teeth were polished on a monthly basis, and oral hygiene was reinforced to control gingival enlargement. Gingival hypertrophy recurred slightly, and gingivectomies were performed in the months following the start of orthodontic treatment. Follow-up was performed for 24 months with orthodontic retention, and gingival enlargement remained stable after the combined treatment.
The risk of gingival hyperplasia recurrence during and after orthodontic treatment is high, but satisfying long-term outcomes can be achieved with gingivectomy, malocclusion correction, and regular follow-up maintenance.
遗传性牙龈纤维瘤病（Hereditary gingival fibromatosis，HGF）在临床实践中较为罕见，且 HGF 的正畸-牙周联合治疗的长期效果鲜有报道。
本研究首次报道了一例 HGF 七岁女童七年随访的结果。通过临床体征、家族史和组织病理学检查确诊。首先，在混合牙列期定期进行牙周洁治和口腔卫生强化。接着，在恒牙列期进行牙龈成形术。术后两个月，开始固定正畸治疗。每月对牙齿进行抛光，强化口腔卫生以控制牙龈增生。牙龈增生略有复发，在正畸治疗开始后的几个月内进行了牙龈切除术。正畸保持 24 个月后进行随访，联合治疗后牙龈增大保持稳定。
正畸治疗期间和之后，牙龈增生复发的风险较高，但通过牙龈切除术、错颌矫正和定期随访维持，可以获得满意的长期效果。
