Complex odontoma: report of a five-year follow-up case.

Odontomas are odontogenic tumors that usually present as benign lesions. They are easily diagnosed and affect individuals in their first and second decades of life. In most cases, odontomas are asymptomatic and the presence could be suspected due to the delay in tooth eruption or via routine radiographic examinations. Treatment of choice has been surgical removal of the lesion, and prognosis is usually favorable because of its benign characteristics and rare recurrence. The purpose of this study is to report the case of a complex odontoma in a child impacting a permanent molar and preventing its eruption. The lesion was surgically removed, and the eruption of the permanent mandibular left second molar tooth occurred after 5 months. Clinical, radiographic, and histopathological characteristics were studied in this case.
