    Abstract:
    BACKGROUND Hereditary gingival fibromatosis is characterized by slowly progressive enlargement of the gingiva that can present as an isolated condition or present as part of various syndromes. CASE REPORT An 11-year-old female reported with a gingival lesion that caused masticatory problems and poor oral hygiene. Periodontal examination revealed a dense tissue covering 30% of her teeth crowns within both jaws. Panoramic x-ray showed a normal bone height and teeth positioning. The patient did not use any medications, but a similar condition was also present in other family members. The patient was diagnosed with hereditary gingival fibromatosis. Surgery was carried out to remove excess of gingival tissue. Post-surgical healing was uneventful, but four weeks after the first surgery, the condition recurred amounting to 45% of the initial tissue volume presenting in the mandible, and 25% in the maxilla. Two months later, no significant growth was noted in the mandible, while in the maxilla, growth increased to 40% of the preoperative state. Analysis by polarized microscope showed a significant increase of thin fibrotic fibrils that contributed 80% of the total pool of collagen fibrils in the patient's gingiva, but only 25% in healthy gingiva. The patient was receiving outpatient care for follow-up every three months and surgical intervention had not been planned as long as her periodontal health was not be compromised.  CONCLUSIONS It is currently not clear whether the extent of the fibrosis had a mechanistic association with the ratio of gingival tissue re-growth in our case study. Further studies are needed to explain this association and improve the management of this condition.
