Localization of anatomic structures before endodontic surgery with tomograms. Report of a case

Tomograms taken before endodontic surgery can demonstrate the location of root apices relative to adjacent anatomic structures. This buccolingual perspective is not depicted on conventional periapical or panoramic radiographs. Accurate length determination from the root apex to the inferior alveolar canal is simplified, and the relationship of root surfaces to the buccal and lingual plates is well visualized on the tomographic images.
