Compound Odontoma in Canine Region and its Radiological Evidence: Case Reports

Compound odontoma (CpOD) develops tooth germ-like structures but often lacks complete differentiation. Some authors recognize the compound odontoma as supernumerary teeth.

This study aimed to present the analysis of orthodontic problems and radiological findings in three clinical cases of patients with complex odontoma.

The present three clinical cases of patients (two females and a male), aged from 14 to 25 years, had compound odontoma, which was confirmed through their radiological findings. Patients did not report symptoms associated with pain and discomfort in the area or genetic predisposition in the family. Orthodontists examined each clinical case with its individual problems and solutions. The findings were localized in the canine region, in 2 of the cases in the upper jaw and one in the lower. Only one patient with localization of the problem in the lower jaw had no disturbance in the eruption of the teeth in the affected dental arch, while in two patients with localization of the problem in the upper jaw, retention of permanent canines was found. In all three cases of the odontoma, there was one tooth with the reverse direction of the crown root. In one case, a supernumerary tooth near the odontoma was also observed. In all of the presented cases involving compound odontoma, there was one main well-formed and developed tooth, around which the other tooth-like structures were located, usually with a conical shape.

CBCT contributes to establishing an accurate and detailed morphological characterization of the fundamental structures (teeth) in the odontoma.
