Their tendency to grow in size may also contribute to periodontal disease as a result of food build up in the area of the lesion. [ 11 ] Radiographically, buccal exostoses can be identified as round, well-defined structures which superimpose the roots of the teeth, normally in the premolar and molar region.
Necrotic bone does not undergo resorption; therefore, it appears relatively more opaque. Attempts at repair of ischaemic-damaged bone will usual occur in 2 phases. First, when dead bone abuts live marrow, capillaries and undifferentiated mesenchymal cells grow into the dead marrow spaces, while macrophages degrade dead cellular and fat debris ...
Exposed and necrotic bone or a fistula that probes to bone in patients with pain, infection, and one or more of the following: exposed and necrotic bone extending beyond the region of alveolar bone,(i.e., inferior border and ramus in the mandible, maxillary sinus and zygoma in the maxilla) resulting in pathologic fracture, extra-oral fistula ...
OM may occur by direct inoculation of pathogens into the bone (through surgery or injury), by spread of an adjacent area of infection or by seeding of the infection from a non adjacent site via the blood supply (hematogenous spread). Unlike OM of the long bones, hematogenous OM in the bones of the jaws is rare. OM of the jaws is mainly caused ...
A jaw abnormality is a disorder in the formation, shape and/or size of the jaw. In general abnormalities arise within the jaw when there is a disturbance or fault in the fusion of the mandibular processes. The mandible in particular has the most differential typical growth anomalies than any other bone in the human skeleton.
An intact prehistoric mastodon jaw was discovered in the backyard of a Hudson Valley house after the homeowner initially saw a pair of teeth poking up by a plant, according to state officials.
Phossy jaw, formally known as phosphorus necrosis of the jaw, was an occupational disease affecting those who worked with white phosphorus (also known as yellow phosphorus) without proper safeguards. It is also likely to occur as the result of use of chemical weapons that contain white phosphorus.
Abnormal tooth position, such as tooth crowding, giving inadequate cover of one or more teeth by the jaw bone. [1] Piercings in the lip or tongue that wear away the gum by rubbing against it. [8] [9] Intentional gingival retraction. For example, the adult tooth may not grow out of the gum, and to remedy this, a procedure called an exposure is done.
