Odontoma is considered to be the most common odontogenic tumor of the oral cavity. Most odontoma
are discovered during routine radiographic investigations and can cause disturbances in the teeth eruption.
Here we report two cases, where the odontoma are the main etiological factor for tooth impaction. The aim
of this study is to determine the necessity of the removal of the odontoma as a main etiological factor for
tooth impaction in order to induce successful tooth eruption. In the first case, a radiography examination
using orthopantomogram showed radio-opaque lesions mesial to the impacted right mandibular canine. The
lesion was surgically removed under local anesthesia. After mucoperiosteal flap was raised, superficial bone
was removed followed by the removal of the calcified structures. The flap was approximated and sutured. In
the second case, a radiography examination using CBCT revealed presence of radio-opaque lesions next to
the unerupted left maxillary canine. Surgery was performed under local anesthesia. After the primary canine
was removed, the odontomas were removed in order to establish eruption path for the canine. The results of
this study show that using the appropriate surgical protocols that eliminate odontogenic lesions can establish
adequate environment for teeth to erupt. Diagnosis of odontoma at an early age and its surgical excision may
prevent eruption disturbances. A careful follow-up of the case, implementing preventive and interceptive
orthodontics, if necessary, prevents future malocclusion.
