Temporomandibular joint dysfunction (TMD, TMJD) is an umbrella term covering pain and dysfunction of the muscles of mastication (the muscles that move the jaw) and the temporomandibular joints (the joints which connect the mandible to the skull).
Headache or facial pain, as in the descriptive former term "neuralgia-inducing" (cavitational osteonecrosis). Fibromyalgia. Chronic fatigue syndrome. Swelling. External swelling is initially due to inflammatory edema with accompanying erythema (redness), heat and tenderness, and then later may be due to sub-periosteal pus accumulation ...
Pain, inflammation of the surrounding soft tissue, secondary infection or drainage may or may not be present. The development of lesions is most frequent after invasive dental procedures, such as extractions, and is also known to occur spontaneously. There may be no symptoms for weeks or months, until lesions with exposed bone appear. [5]
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.
While the exposed, dead bone does not cause symptoms these areas often have mild pain from the inflammation of the surrounding tissues. [15] Clinical signs and symptoms associated with, but not limited to MRONJ, include: Jaw pain and neuropathy [16] Loose teeth [17] Mucosal swelling [17] Erythema; Suppuration [17]
It is classified as a benign fibro-osseous lesion of the jaw, which means it contains both fibrous tissue and bone like structures. The tumor is a slow growing lesion that can cause the maxilla and the mandible to expand causing a shift in the teeth. There is an inflammatory response due to the tumor leading to discomfort and pain of the jaw.
Temporomandibular joint pain is generally due to one of four reasons. Myofascial pain dysfunction syndrome, primarily involving the muscles of mastication. This is the most common cause. Internal derangements, an abnormal relationship of the disc to any of the other components of the joint. Disc displacement is an example of internal derangement.
Jaw cysts affect around 3.5% of the population. 10 They are more common in males than females at a ratio of 1.6:1 and most people get them between their 40s and 60s. The order of the jaw cysts from most common to least common is; radicular cysts , dentigerous cysts , residual cysts and odontogenic keratocysts .
