Which symptom is NOT typically associated with a TMJ dislocation?

• A. Inability to close the mouth
• B. Severe jaw pain
• C. Clicking sound when moving the jaw
• D. Swelling of the jaw

Answer: (C)

A clicking sound when moving the jaw is typically associated with TMJ disorders, particularly in cases of internal derangement or other forms of TMJ dysfunction, rather than a dislocation. Dislocations often manifest with more acute symptoms, such as an inability to close the mouth, which indicates that the jaw is locked open or in an abnormal position. Severe jaw pain is common due to the strain on the muscles and ligaments around the joint from the dislocation. Swelling of the jaw can also occur in response to trauma or inflammation associated with their condition. Thus, while clicking may occur in chronic TMJ dysfunction or other issues, it is not a defining symptom of TMJ dislocation specifically.
