Examination of tempro-madibular joints normally consists of.. Single opened mouth view

Examination of tempro-madibular joints normally consists of:

  • A- Single closed mouth view.
  • B- Film with mouth opened and closed.
  • C- Single opened mouth view.
  • D- Films while patient chews gum.

The most accurate answer for the examination of temporomandibular joints (TMJs) is: B. Films with mouth opened and closed.

Here's why the other options are not ideal:

A. Single closed mouth view:

This provides limited information about the joint position and potential problems. It's not sufficient for a comprehensive assessment of the TMJs.

C. Single opened mouth view:

While this offers some information about joint movement, it doesn't capture the full range of motion or potential imbalances.

D. Films while patient chews gum:

This can be a useful additional test in specific situations, but it's not a standard part of the initial TMJ examination. Chewing forces might not accurately replicate all types of TMJ movement and could potentially exaggerate existing issues.

Standard TMJ Examination:

Therefore, standard TMJ examination typically includes:

- Palpation:

Manual examination of the TMJs for tenderness, swelling, or clicking sounds.

- Range of motion testing:

Assessing the patient's ability to open and close their mouth comfortably and smoothly in various directions.

- X-rays:

Taking radiographs with the mouth both closed and open to visualize the TMJ structures, their alignment, and potential abnormalities.

The specific X-ray views used may vary depending on the suspected problem and the dentist's preference. However, capturing both open and closed mouth positions is essential for a complete picture of the TMJ joint dynamics and potential issues.

Remember, proper diagnosis and treatment of TMJ disorders require a comprehensive evaluation, including clinical examination, imaging, and patient history. Consult with a qualified dentist or TMJ specialist if you experience any TMJ-related symptoms like pain, clicking sounds, or difficulty chewing.
