The following Case Challenge is provided in conjunction with the American Academy of Oral and Maxillofacial Pathology.

This case challenge presents a patient with a bone lesion that appeared following the extraction of a mandibular molar.

A 28-year old male patient presented for his routine dental health visit which included the bitewing radiograph shown. The radiograph was taken as a follow-up nine months after the extraction of the mandibular second molar by the oral surgeon. The patient had no discomfort and was unaware of any dental problem.

After you have finished reviewing the available diagnostic information, make the diagnosis.
