Hereditary Gingival Hyperplasia-Case Report

Abstract

This case report is an 11 years old boy with slowly progressive gingival enlargement, supernumerary tooth and dentigerous cyst. The case report addresses oral diagnosis of hereditary gingival hyperplasia (HGF) and management of supernumerary tooth and dentigerous cyst. Gingival tissues surrounding both the maxillary and the mandibular dentition are affected. His mother and distant uncle of his mother also reveal gingival overgrowth. Microscopically, biopsy shows gingival hyperplasia composed of dense proliferative fibrous connective tissue and reactive fibroblasts and giant cells. The overlying epithelium reveals hyperplasia with hyperkeratosis, acanthosis and elongated rete ridges. Surgical removal supernumerary tooth was performed. Marsupialization was done and the size of lesion was. It is recommended that the patients with this condition should be on closely follow up due to the difficulty of oral hygiene maintenance. Due to several ectopic erupting teeth, deep bite and skeletal class II malocclusion with high mandibular angle, the orthopedic treatment proceeded for occlusion guidance. The fall mouth periodontal treatment is also needed. While clinicians disagree on the modalities and timing of treatment for HGF, the clinical condition generally requires repeated periodontal surgical procedures of resection over the patient's lifetime.
