CPC Case #4
Provided By: Yi-Ling Lin DDS, DMSc - 2010-05-12
Clinical History
A 25-year-old Caucasian woman was referred to an oral surgeon by her general dentist for evaluation of a unilocular radiolucency between teeth #26 and #27. The patient had no clinical symptoms and the teeth were stable and vital. However, the lesion had eroded a small area of cortical bone in the facial papilla region. Although no radio-opacity was noted in the radiograph, during the surgery, the surgeon described the content of the lesion as mixtures of soft and solid materials.
