Odontomas are hamartomatous developmental malformations of the dental tissues. Usually asymptomatic, their presence is often revealed on routine radiographs. The study aimed to establish the efficacy of this conventional approach in treating odontomas, analysing clinical outcome, follow-up, and histomorphological profile. In this case report the patient, aged 8 years, had a complex odontoma localised on the front upper jaw. She was treated following the conventional surgical procedure. Post-operative course and healing were uneventful. Orthodontic treatment was necessary to realign the teeth. At the 12-month follow-up there was no recurrence or failure. Healing was excellent. Variations in normal tooth eruption are a common finding, but significant deviations from established norms should alert the clinician to further investigate the patient’s health and development.
