A case of follicular dental cyst associated with odontoma

Follicular dental cyst associated with odontoma is relatively rare. We encountered an 84-year-male with a follicular dental cyst associated with odontoma in the right mandible. The cyst included the crown of an impacted tooth (2).The odontoma was classified as compound odontoma. The cyst and odontoma were removed under local anesthesia. The postoperative course was uneventful. In the infrared spectroanalysis, it was suggested that calcification of the odontoma was less than that of the impacted tooth.
