Clinical Presentation

Overview of TMJ Arthritis

Arthritis of the temporomandibular joint involves inflammation of the joint that connects the jawbone to the skull. This condition can arise from various causes, including osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis. The clinical presentation may vary based on the underlying cause and the severity of the condition.

Common Signs and Symptoms

Patients with TMJ arthritis typically present with a range of signs and symptoms, including:

• Pain: The most common symptom, often described as a dull ache or sharp pain in the jaw, which may radiate to the ear, neck, or head. Pain can be exacerbated by jaw movement, such as chewing or speaking[1].
• Swelling: Inflammation may lead to visible swelling around the TMJ area, which can be assessed during a physical examination[2].
• Limited Range of Motion: Patients may experience difficulty opening their mouths fully (trismus) or may have a restricted range of motion due to pain or mechanical issues within the joint[3].
• Clicking or Popping Sounds: Noises during jaw movement, such as clicking, popping, or grinding, may indicate joint dysfunction or displacement of the articular disc[4].
• Headaches: Tension-type headaches or migraines can occur secondary to TMJ dysfunction and pain[5].
• Ear Symptoms: Patients may report ear pain, a feeling of fullness in the ear, or tinnitus, which can be related to TMJ issues[6].

Patient Characteristics

Demographics
