Abstract
The odontoma is a hamartoma of odontogenic origin and consists of enamel, dentin, cementum and pulp tissue. Two types of odonotma are histologically recognized: complex and compound. Odontoma may be the cause of noneruptoin or impaction of teeth, formation of cyst and resorption of adjacent bone. The recommended treatment for an odontoma is conservative surgical excision. No propensity for recurrence has been noted. Peripheral odontoma is relatively rare lesion and shows the histological characteristics of an intraosseous odontoma. This report described a 3-year-old Korean girl with a firm gingival mass in the posterior mandibular area, which had been gradually enlarging over 18months. Radiographic examination showed a radiopaque mass but no evidence of underlying intraosseous lesion. Excisional biopsy was performed for the mass removal and histopathological examination. The result of histopathological study was identified as hamartous supernumerary tooth germ. Based on the clinical presentation, radiographic and histopathologic findings, we concluded that the final diagnosis was peripheral odontoma. For three years after surgery, there is no clinical sign of recurrence.
