Temporomandibular joint disorder
Temporomandibular Joint Disorder
Temporomandiburlar joint disorder (pronounced tem-puh-roh-man-dib-yuh-lar), often abbreviated as TMJ disorder or simply TMJ, is a condition affecting the temporomandibular joint, which connects the jaw to the skull. The term "temporomandibular" is derived from "temporal," referring to the temporal bone of the skull, and "mandibular," referring to the mandible or lower jawbone.
Symptoms
Symptoms of TMJ disorder can vary widely but often include pain or discomfort in the jaw, difficulty chewing, and a clicking or popping sound when the jaw is moved. Other symptoms may include ear pain, headaches, and facial pain.
Causes
The exact cause of TMJ disorder is often difficult to determine. It may be due to a combination of factors, such as genetics, arthritis, or jaw injury. Some people who have jaw pain also tend to clench or grind their teeth, although many people habitually clench or grind their teeth and never develop TMJ disorders.
Diagnosis
Diagnosis of TMJ disorder typically involves a physical examination of the jaw and face, a review of the patient's medical history, and possibly imaging tests such as X-rays, CT scans, or MRI scans.
Treatment
Treatment for TMJ disorder can range from self-care practices and physical therapy to injections, dental splints, or surgery. The specific treatment approach depends on the severity of the symptoms and the underlying cause of the disorder.
