Temporomandibular joint disease

Introduction to temporomandibular joint disease Temporomandibular arthritis, a condition of the joint between the jaw and the ear, is also a common source of pain. Put your fingers in front of the ear canal on both sides and open your mouth to hear a crack-like sound. The symptoms of temporomandibular arthritis are very common. This includes local joint pain, ear pain, headache, noise, and pain during chewing, as well as pain associated with various muscles. The degree of opening the mouth is limited, and sometimes it is difficult to swallow food. basic knowledge The proportion of illness: 0.052% Susceptible people: no special people Mode of infection: non-infectious Complications: malnutrition, sleep apnea syndrome, tinnitus

Causes of temporomandibular joint disease

Physical and chemical factors (30%):

Some scholars believe that mechanical damage, biochemistry and enzyme interaction can lead to the occurrence of osteoarthrosis.

Disease factor (30%):

Local factors of osteoarthritis are the main causes, such as the joint continues to withstand abnormal pressure, bite hard objects, unilateral chewing, disease, clenched teeth, trauma, car accident, first external force of the lower jaw, etc. Arthropathy occurs.

Pathological factors (25%):

Epidemiological investigations have found that the incidence of osteoarthrosis accounts for a large proportion in the elderly. This may be due to the aging, the biochemical components, enzymes and morphology of joint tissues are changed, and the resistance to damage is reduced.

Physiological factors (15%):

Disorders of occlusion, malocclusion, and occlusion can also lead to osteoarthrosis. The movement of the temporomandibular joint disc and the perforation of the articular disc are related to osteoarthrosis, but osteoarthrosis can also cause displacement of the articular disc and perforation of the disc.

Temporomandibular joint disease prevention

The disease is often caused by a combination of factors, and mental and psychological disorders, relationship disorders, bad oral habits, therefore, the key to prevent this disease is to regulate the pace and order of life, reasonable diet, keep the mouth clean, exercise. It is especially important to have regular oral examinations and early treatment of abnormalities. For those who are ineffective in active treatment, they should be highly alert to malignant tumors in the mouth and ears.

Temporomandibular joint disease complications Complications malnutrition sleep apnea syndrome tinnitus

Difficulties in opening caused by this disease, such as long course of disease, can cause malnutrition; the occurrence of joint stiffness in young children will affect the development of the mandible, severe deformity may be associated with sleep apnea syndrome. Joint pain, ankle pain, tinnitus, dizziness.

Temporomandibular joint disease symptoms Common symptoms Jaw joint pain, mouth and jaw

Osteoarthrosis is more common in adults around the age of 45. There is no significant difference in the incidence of male and female, the course of disease is prolonged, and there are acute and chronic disorders. Joint pain can occur during the polar phase, which is associated with degenerative wood and synovitis. Joint pain is aggravated during opening, closing, and chewing, and joint pain occurs in some patients when jaw movement stops. There is pain in the masticatory muscles, but many patients have no joint and masticatory muscle pain, only joint murmurs. Patients with hyperosteogeny, osteophytes, and perforation or rupture of the articular disc can smell joints, frictional sounds, and broken sounds.

Examination of temporomandibular joint disease

Articular X-ray films showed degenerative changes in joint space stenosis, condyles, joint sockets, and joint nodules. Arthrography or magnetic resonance showed changes in disc displacement, disc perforation, and rupture.

Diagnosis and diagnosis of temporomandibular joint disease

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

The temporomandibular joint disorder syndrome, temporomandibular joint ankylosis, and temporomandibular joint dislocation were identified.
