Introduction[edit | edit source]

Figure 1. Temporomandibular joint.

The temporomandibular joint (TMJ) is considered one of the most complex joints in the body. It plays a significant role in dental occlusion and the neuromuscular system.[1]

It has been classified as both a compound joint and a double joint. Compound joints typically consist of three or more bones, but the TMJ only has two bones. Instead of a third bone, an articular disc sits between the mandibular fossa and the condyle (Figure 1).[1]

The anatomy, biomechanics and physiology of the TMJ are discussed in detail here and here.

Causes of Facial Pain[edit | edit source]

Temporomandibular disorders (TMDs) are the most common non-dental cause of facial pain. Other acute causes of facial pain are:[2]

  • Dental and oral causes
  • Maxillary sinusitis
  • Salivary gland disorders
  • Neuropathic pain (trigeminal nerve region), such as:
    • Trigeminal post-herpetic neuralgia
    • Post-traumatic trigeminal pain / trigeminal neuropathic pain / atypical odontalgia
    • Burning mouth syndrome
    • Trigeminal neuralgia and its variants etc
  • Vascular causes
    • Giant cell arteritis should be considered in individuals aged over 50 years who present with temporal pain that mimics TMD
