Huge erupted complex odontoma in maxilla

Abstract Objective Odontoma is the most common odontogenic origin benign tumor considered to be hamartoma. It is characterized by its slow-growth and non-aggressive behavior. Those erupting to oral cavity are called “erupted odontomas” are rarely seen. Methods Here we report a rare case of a large erupted complex odontoma in maxilla, presenting clinical and radiographic features and treatment. Results Most odontomas are asymptomatic, but those erupting to oral cavity may cause severe infection. Bone loss and teeth impaction will greatly influence patients’ function. Conclusions Routine X-ray examination is necessary in mixed dentition period. Once odontoma is diagnosed, early surgical removal is the best choice.
