We report a case of a compound odontoma in the lower left canine and premolar regions complicated by impacted lower left canine and first premolar. The patient was a 12 year 10 month old girl, complaining of prolonged retention of deciduous canine and first premolar, and also crowding of maxillary anterior teeth. She had no subjective symptoms, however slight elevation was found on the lower left canine and premolar region of alveolar process. Based on X-ray findings, a cherry-sized compound odontoma was discovered close to the apex of the lower left primary canine and first premolar. It consisted of a great many tooth-like pieces. The border was distinguished clearly. The lower left canine was impacted horizontally in the medial portion of the mandibular bone, and the lower left first premolar was located adjacent to the apex of the lower left second premolar. The odontoma was removed and also the lower left canine was extracted under local anesthesia. After the removal of the odontoma, the lower right first premolar and both upper first premolars were extracted in order to dissolve the teeth to denture base discrepancy, and then orthodontic treatment was performed. The lower left first premolar migrated medialy and erupted 2 years 2 months after the operation. This tooth was aligned and good permanent occlusion was obtained.
