Clinical and Radiographic Findings

The lesion was discovered on a routine panoramic radiograph to evaluate the patient’s third molars.  At presentation there was no evidence of swelling or pain.  The panoramic radiograph showed a large radiolucency with a scalloped border squeezing between teeth #s 30 & 31.  Mesially, this large radiolucency appeared as if it was connected to the crown of tooth #32.  The cross-sectional images, however, demonstrated a very thin line of separation between the follicle of tooth #32 and the large radiolucency mesial.
