Odontomas are defined as hamartomas of odontogenic origin. They are composed of all dental tissues are represented, occurring in a more or less disorderly pattern. Intraosseous (central) odontomas are the odontogenic tumors of greatest incidence. Otherwise, odontomas arising in the extraosseous soft tissue, also known as peripheral odontoma, are extremely uncommon. This article presents a case of peripheral odontoma in a child referred to SNUDH for treatment. A 2-year-old girl was referred to The SNUDH regarding an asymptomatic nodule on the left maxillary buccal gingiva. Clinical examination revealed a 7 mm × 6 mm × 3 mm, sessile mucosal lesion on the buccal gingival between #62 and #63. The lesion was firm on palpation and covered with an intact non-ulcerated mucosa. There was no other mucosal pathology. Under N2O-O2 inhalation sedation, an excisional biopsy of the lesion was performed. The diagnosis was peripheral odontoma. Summary: Odontoma in an extraosseous location represents a challenge for diagnosis. This article reports a case of peripheral odontoma and its clinical presentation, histological evaluation and treatment. A 2-year-old girl reported a firm asymptomatic nodule on left maxillary buccal gingival. The procedures for diagnosis included intraoral examination, excisional biopsy and histological analysis. The diagnosis was peripheral odontoma. Peripheral odontoma is rare and the differential diagnosis with other gingival masses is rather difficult and must include inflammatory and reactive processes. The definitive diagnosis is based on microscopic features.
