title: Pathological conditions of the mandible: their effect on the radiographic appearance of the inferior dental (mandibular) canal.
abstract: Whilst the special anatomical features of the mandible may make radiographic comparison of jaw lesions with similar conditions in other bones more difficult, the changes that occur in respect to the mandibular canal and the teeth may in themselves aid diagnosis. Benign cysts and neoplasms generally cause a displacement of the mandibular canal, but its cortical plate remains intact, Severe infections and malignant tumours result in an irregular erosion of bone and loss of the sclerotic outlines of the canal.
