A RADIOGRAPHIC STUDY OF RECURRENT UNICYSTIC AMELOBLASTOMA FOLLOWING MARSUPIALIZATION. REPORT OF THREE CASES

OBJECTIVES To study the radiographic sequence in the recurrence of unicystic ameloblastoma following marsupialization. MATERIALS AND 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. CONCLUSION The first radiographic sign of recurrence is scalloping of the sclerotic margin of the regenerated bone.
