Which of the following accurately describes TMJ dysfunction?

TMJ dysfunction is a complex condition that can be attributed to a variety of factors, making option B the accurate description. It encompasses a broad range of potential causes, which can include muscular issues such as tension or spasm, structural problems of the jaw and teeth alignment, and even psychological factors such as stress that may lead to jaw clenching or grinding. This multifactorial nature of dysfunction emphasizes the need for a comprehensive assessment to identify the underlying causes in each individual case.

The other options present limitations that do not capture the entirety of TMJ dysfunction. For example, while arthritis can contribute to TMJ issues, it is not the sole cause, which invalidates the first option. Additionally, TMJ dysfunction can affect both sides of the jaw, and symptoms may be bilateral rather than unilateral, making the statement that it only affects one side inaccurate. Lastly, neurological factors, including conditions like migraines or trigeminal neuralgia, can indeed relate to TMJ dysfunction, opposing the idea that this condition is devoid of any neurological association.
