A radiographic study of recurrent unicystic ameloblastoma following marsupialization. Report of three cases.
OBJECTIVE
To study the radiographic sequence in the recurrence of unicystic ameloblastoma following marsupialization.


METHODS
Retrospective analysis of three cases of uncystic ameloblastoma.


RESULTS
Six distinct stages were identified in all three cases: bone regeneration starting at the periphery of the cavity; appearance of a diffusely sclerotic band; appearance of scalloping; expansion of scalloping; formation of a multilocular pattern; and enlargement of the cystic lesion.


CONCLUSIONS
The first radiographic sign of recurrence is scalloping of the sclerotic margin of the regenerated bone.
