A case of adenoameloblastic odontoma in the maxillary anterior region was reported. The patient, a 19 year-old woman, complained of occlusal pain at 2.
In the first medical examination, swelling was admitted at 1-3 labial and palatal gingiva region.Radiograph showed a clearly demarcated radiolucent lesion at 2 In pulp test, 2 was non-vital, and 13 were vital.
We performed enucleation and apicoectomy of 23.The tumor had a well defined fibrous capsule, so we easily removed the tumor.The tumor, presented globulary, was measured in a region of about 16 mm which included hard tissues.
Microscopically, this tumor was encapsulated with thin fibrous tissues.The calcified tissues and odontogenic epithelia could be observed in the tumor.The calcified tissues were analogous to odontoma which contained regular and irregular dentinal tubules. The odontogenic epithelia revealed various patterns, i.e.sheet-like, adenomatoid and follicular struc tures.The adenomatoid structures were composed of cuboid cells, and the pscudoluminal region was occupied by fine fibrous materials.The present case was pathologically diagnosed as adenoameloblastic odontoma.6 months have passed, and there have been no symptoms of recurrence.
