History of the present illness

This is a 58-year-old male who was referred by his dental hygienist for evaluation of an anterior mandible midline bony lesion that had been present for several months. The patient had noticed loosening in his anterior mandibular teeth six months prior. He also reported a recent infection in the area that had been treated with antibiotics. At presentation, the area was swollen but not infected and the anterior mandibular teeth demonstrated 3+ mobility. Periapical radiographs demonstrated an ill-defined radiolucency with displaced teeth (Figures 1 & 2). The teeth were otherwise vital.

Figure 1 This radiograph was taken in first clinical presentation. Note the ill-defined radiolucency involving multiple teeth in the anterior mandible.
