case_images: A 78-year-old patient was first observed in December 2008 at the Complex Operative Unit of Oral Surgery at the Department of Odontostomatological and Maxillofacial Sciences of the "Sapienza" University of Rome due to a small, symptomless, localized swelling at the right inferior alveolar process, between the canine and the first premolar which appeared spaced several millimeters each other (Figure 1).
case_images: Orthopantomography at first visit showed a homogeneous, radiolucent, oval-shaped, unilocular area, which appeared quite well-delimited by a peripheral radiopaque and slightly scalloped border.

case_images: The orthopantomography showed a homogeneous, radiolucent, oval-shaped, unilocular area, well-delimited by a peripheral radiopaque and slightly scalloped border, involving the roots of the canine and the first premolar and vertically oriented, from the top of the alveolar process up to about 1 cm below the apices of the neighboring teeth (Figure 2).
case_images: Orthopantomography 1 year after initial treatment: a radiolucent area was detected in the middle of the mineralizing bone tissue.
