Odontomes associated with primary teeth are rare. This report describes two cases of compound odontome associated with impacted maxillary primary central incisors in patients aged 1 year 8 months and 1 year 2 months, the latter being the youngest to have been reported with the condition. The odontomes were removed under local anaesthesia. Histological examination revealed immature dental tissues in both cases, but no evidence of root formation. Case 1 revealed 'ghost cells' within the enamel epithelium. The impacted incisors erupted following removal of the odontomes; in Case 2 the crown had an unusual ridge on its labial surface, extending from the gingival margin to a few millimetres from the incisal edge.
