Temporomandibular joint Disorders treatment in Mangalore

The jawbone and the skull are connected by the temporomandibular joint, which acts as a sliding hinge. Temporomandibular joints are located on both sides of the face, just in front of the ears. Temporomandibular joint (TMJ) disorders cause pain in the jaw joint and within the muscles responsible for controlling the jaw movement. It affects the jaw joints along with the surrounding muscles and ligaments. 

Temporomandibular joint (TMJ) disorders are basically a class of degenerative musculoskeletal conditions involving morphological and functional deformities. These conditions may be acute or chronic, and the pain may be mild as well as severe. Research studies have revealed that TMJ disorders have affected 25% of the total population. TMJ disc dislocation accounts for approximately 70% of all cases. Book an appointment at our Dental medicine hospital in Mangalore.

What Causes Temporomandibular Joint (TMJ) Disorders?

TMJ disorders occur due to injuries in the jaw joints, but their most appropriate causes are still not determined. Research studies have recommended some factors, such as combinations of genes, and psychological and life stressors, as the reason for pain persistence to be the cause of TMJ disorders. It is more common in women than in men, so researchers are determining the differences in the anatomy and mechanisms between females and males. Some other causes of TMJ disorders include:

  • Physical injury

  • Arthritis

  • Grinding or cleaning the teeth during sleep

  • Autoimmune diseases

  • Dental surgery

  • Infections

  • Stress

  • Acute trauma

  • Inappropriate chewing

Other causes may include genetic, hormonal, and environmental factors, poor diet, and lack of sleep. To know more about TMJ, consult with our Dental medicine specialist in Mangalore.

How are TMJ Disorders Diagnosed?

Any dysfunction in the TMJ is diagnosed by undergoing dental check-ups. Healthcare providers usually diagnose TMJ disorders by:

  • Observing motion range during the opening and closing of the mouth

  • Pressing on the face and jaw is done to identify the region of discomfort

  • Observe the feeling of the person around the jaw joints as you open and close the mouth.

Some imaging tests are conducted to view the jaw joints and determine the level of damage in the jaw joints. These tests include:

  • Panoramic X-rays

These are the types of dental X-rays that represent a broader overview of the teeth, jawbone, and TMJs.

  • Cone beam computed tomography (CBCT) scans

It aims to capture several images of teeth, jaws, facial bones, and sinuses in the form of 3-D images.

  • MRI scans

It helps to view the soft tissues in and around the jaw joints. The images obtained from MRI scans represent the position of the disk, inflammation, and possible jaw locking. It helps healthcare providers determine the appropriate function and condition of the TMJ disc.

  • Surgical and other procedures

Some surgical approaches include

  • Arthrocentesis

Care for patients with TMJ disorders

  • Practising correct posture to reduce neck and facial pain is key.

  • Placing the tongue on the palate behind the upper front teeth to avoid clenching and grinding in the daytime

  • Learning relaxation techniques to control the muscle tension in the jaw is a must.
