Answer :
Final answer:
TMJ dysfunctions involve injuries, mechanical problems, and degenerative changes, along with disc issues and ligament thickening. The correct option is b) Entrapped, deformed, or torn disc.
Explanation:
Temporomandibular joint (TMJ) dysfunction encompasses a range of conditions affecting the joint connecting the jawbone to the skull. Among the factors listed, an entrapped, deformed, or torn disc within the TMJ is a common cause of dysfunction.
The TMJ disc acts as a cushion between the jawbone and the skull, facilitating smooth movement during activities like chewing and talking. When this disc becomes entrapped, deformed, or torn, it can lead to various symptoms including pain, clicking or popping sounds, limited jaw movement, and muscle stiffness. This dysfunction can result from trauma, such as a direct blow to the jaw or a sudden impact, as well as from chronic habits like teeth grinding or clenching.
