Post radiation maxillary bone osteonecrosis is something that is found more in the lower jaw (mandible) rather than the maxilla (upper jaw) this is because there are many more blood vessels in the upper jaw. [7] The symptoms of this are very similar to the symptoms of medication-related osteonecrosis of the jaw (MRONJ). Patients are in a lot of ...
The symptoms are necrosis of the mandible (lower jawbone) and the maxilla (upper jaw), constant bleeding of the gums, and (usually) after some time, severe distortion due to bone tumors and porosity of the lower jaw. Symptoms also include soreness throughout the body, significant decrease in body weight and loss of teeth.
Although the methods of action are not yet completely understood, it is hypothesized that medication-associated osteonecrosis of the jaw is related to a defect in jaw bone healing and remodelling. The inhibition of osteoclast differentiation and function, precipitated by drug therapy, leads to decreased bone resorption and remodelling.
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.
Localized osteomyelitis tended to be described as either vertical, where a short segment of the body of the mandible from the alveolar crest to the lower border was involved, and alveolar, where a segment of alveolar bone down to the level of the inferior alveolar canal would sequestrate, including the sockets of several teeth.
The second branch provides feeling to the cheek, jaw, top lip, upper teeth and gums, while the third branch provides sensitivity to the lower jaw, teeth and gums. Jackie Galgey at hospital ...
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. [1] Early on, there may be no symptoms. [ 1 ] Gradually joint pain may develop, which may limit the person's ability to move. [ 1 ]
