Abstract

<p>Gingival fibromatosis (GF) is a rare disease characterized by gingival hyperplasia that occurs in early childhood and progresses slowly. We report a case of canine impaction and embedded supernumerary teeth occurring bilaterally in the maxilla with GF.</p><p>The patient was a boy of six years and six months with delayed eruption of his permanent teeth. As oral findings, the crowns of the maxillary teeth were slightly erupted from the gingiva, which was enlarged remarkably. Because of similar oral findings in his brother, this GF was diagnosed as a hereditary disease.</p><p>Bilateral canine impaction and embedded supernumerary teeth in the maxilla were confirmed by panoramic radiography at age eight years and eight months. GF was treated by gingivectomy under general anesthesia and the impacted canines by fenestration at age nine years and eight months. The embedded supernumerary teeth were extracted under general anesthesia when the boy was ten years and six months. Because of periodic oral management that has contributed to good plaque control, gingival hyperplasia has not recurred after treatment.</p><p>In the future, the patient plans to undergo orthodontic treatment. Therefore, long-term observation and continued oral hygiene management are important to prevent the recurrence of GF.</p>
