This is a 39-year-old Asian female who presented with an expansile and well-demarcated radiolucency involving teeth #s 30 & 32 (Figure 1). The panoramic radiograph demonstrates a large and well-defined unilocular radiolucency with a second more radiolucent destruction in the area apical to tooth #30 indicating perforation of the lingual, buccal or both plates. Tooth #30 was non-vital and both teeth #s 30 & 31 show evidence of root resorption. The past medical history is negative for any significant disease or risk factors.
Figure 1 This is a panoramic radiograph taken at first clinical presentation. Note the large, well-defined unilocular radiolucency involving area of teeth #s 30-32. Also note the more radiolucent small round lesion apical to tooth #30 indicating bone perforation.
