History of the present illness

This is a 53-year-old Asian female who presented with an expansile and well-demarcated radiolucency involving teeth #s 28 &30 (Figures 1 & 2) of 18 months' duration. The panoramic radiograph indicates a partially corticated and otherwise well-defined unilocular radiolucency with a second, more radiolucent destruction in the superior area between teeth #s 29 & 30. The latter area corresponded to buccal and lingual bone perforation. Teeth #s 28-30 were vital. Clinically, the lesion is described to be around 3.5-4 cm in size.

Figure 1 This is a panoramic radiograph taken at first clinical presentation. Note the partially corticated unilocular radiolucency in some areas and well-defined radiolucency in other areas all involving teeth #s 28-30. Also note the more radiolucent small round lesion superior and between teeth #s 29 & 30 indicating bone perforation.
