Anterior lingual mandibular bone concavity. Report of a case.

A lingual mandibular bone concavity in the central incisor region is described. The radiographic appearance of the concavity in this area is an uncommon finding. A review of the literature is presented along with the report of this case. An exact diagnosis of this lesion can be made only by surgical intervention and histologic examination. However, the axial occlusal radiographic view is thought to be helpful in diagnosing this lesion clinically.
