परिभाषा

Temporomandibular disorder (TMD) is a painful condition in the joint that opens and closes the mouth. These temporomandibular joints are the small joints in front of each ear. They attach the lower jaw (mandible) to the skull. The disorder may affect the jaw joint or the muscles surrounding it.

  • Range of motion of the jaw tests
  • Listening for sounds of popping or clicking in the temporomandibular joints
  • Visual inspection of your teeth, temporomandibular joints, and muscles of your face and head
  • Palpation of the joints and the muscles of the face and head

अन्य परीक्षणों में शामिल हो सकते हैं:

  • X-rays—plain x-rays or panoramic dental x-rays of the jaw and jaw joint
  • Arthrography—jaw movements videotaped with x-rays taken after dye is injected into the joint
  • MRI scan—a test that uses magnetic waves to create detailed images of the joint

उपचार

उपचार में शामिल हो सकते हैं:

जीवनशैली के उपाय

  • Rest the jaw with a soft diet
  • Restrict movement with smaller bites
  • Apply warm packs for pain relief
  • Cognitive behavior therapy may help some learn to avoid clenching and grinding their teeth

दवाएं

The most commonly used medicines include:

  • एसिटामिनोफेन (टाइलेनॉल)
  • नॉन स्टेरिओडल आग रहित दवाई
  • मांसपेशियों को आराम देने वाले
  • Low-dose antidepressants

Some medication may be injected into the jaw such as:

  • Pain relieving medicine (such as cortisone or lidocaine)
  • Botulinum toxin (Botox)—may offer temporary relief if pain or clicking are major symptoms

शारीरिक चिकित्सा

To help reduce pain and allow muscles to relax:

  • Gentle massage or stretching exercises
  • ट्रांसक्यूटेनस इलेक्ट्रिकल नर्व स्टिमुलेशन (TENS)

Stress Reduction

Some may benefit from counseling to learn stress management and relaxation techniques, such as:

  • Biofeedback
  • Cognitive behavioral therapy BE

Dental Procedures

A splint or mouth guard can be made to relax your jaw muscles. This will prevent clenching and grinding of your teeth. The guard is usually worn at night. Correction of bite abnormalities by a dentist or orthodontist is sometimes needed.

Surgical Procedures

Surgical correction is a last resort. Many of the available procedures have not been well-studied for their effectiveness.

रोकथाम

There are no guidelines for preventing TMD. If you have TMD, the following may help prevent symptoms:

  • Ask your dentist if you need a night guard for grinding and clenching of the teeth.
  • Try to limit jaw movements. Learn to relax your jaw. Block a yawn by putting your fist under your chin.
  • Avoid extensive movements of the jaw.
  • Don’t chew gum.
  • Learn relaxation techniques. Develop effective ways to cope with stress.
