History of the present illness
This is a healthy 13-year old African American male who first presented for an initial orthodontic examination. Radiographs revealed a large radiopaque and radiolucent lesion associated with an impacted tooth 32. It was approximately 3 x 3 x 4 cm in size. The lesion displaced the 3rd molar posteriorly and up the ramus. Clinical examination of the area showed a normal range of the mandibular motion with no evidence of bony expansion. The overlying and surrounding oral mucosa was unremarkable.
